Superhero Science Trivia

1. The correct answer was GravityGravity is a force that pulls objects together. It's what makes the Earth orbit the Sun and the Moon orbit

the Earth -- it even pulls you a little closer to your computer, but so weakly that you can't feel it! The

gravitational force between us and the Earth is what keeps us on the ground.

2. The correct answer was ArachnidA spider might be hairy, but that doesn't make it

a mammal! It's an arachnid, not an insect; theeasiest way to tell is that it has eight legs, not six.

3. The correct answer was A steel paper clip

Magnetic fields are very powerful, but they work best on certain types of things. Iron

responds very strongly to magnetism, and since steel contains a lot of iron, thosepaper clips will be easy for Magneto to control!

4. The correct answer was Light bounces off of Violet and into their eyes.This is why you see better when there's a lot of light around! Light (from the sun, a light

bulb or a fire) hits objects and people and bounces into your eyes, allowing your brain to

figure out what you're looking at.

5. The correct answer was Bats and submarinesWhen the sounds made by a sonar system hit something and bounce back, the bat (or

submarine) will hear them. They can tell from the echo how far away something is, how bigit is and even (sometimes) what shape it is!

6. The correct answer was LightAlbert Einstein's Theory of Relativity says that nothing can move faster than the speed oflight in a vacuum (like space). Luckily, this still leaves room for the Flash to move very,

very fast: the speed of light is 186,000 miles (or 300,000 kilometers) per second!

Sometimes, the Flash is shown running even faster than light, but even comic book writers


4/178

can't get the science right all the time.

7. The correct answer was EvolutionEvolution slowly changes a species as individuals with helpful mutations have more

children than "normal" individuals without those mutations. It's always happening -- even

today -- but usually over such a long time that we don't notice it.

8. The correct answer was yYou might think of radioactivity as coming from a nuclear bomb or power plant, but even

bombs and power plants use radioactive elements (like uranium) from nature. A radioactive

element will decay into a lighter element, giving off energy.

9. The correct answer was ExoskeletonMany animals, including insects, spiders and lobsters, keep the hardest parts of their bodyon the outside in an exoskeleton. People have endoskeletons (skeletons inside the body) --

and, of course, Iron Man has both!

10.The correct answer was The Milky WayA galaxy is a group of between ten million and a trillion stars, traveling together through the

universe. Our solar system (the Sun, Earth, and the other planets) is only a very tiny part of

our galaxy, the Milky Way -- and there are countless other galaxies in the universe. The

Andromeda Galaxy is the closest to us out of all these other galaxies.

4.In order for particle physicists to know their way through the atom they have tolearn lists of elementary and subatomic particles. Which of the following elementary

particles is commonly associated with light? Say cheese...

Electron


6/178

Photon

Neutrino

Light isn't a particle, surely!

5.In the nucleus of an elemental atom you have one or more protons. All protonshave a positive charge so it would make sense to think that protons within a nucleusrepel each other, but they don't. What is the name of the force that keeps protons

together in the nucleus? You may need big muscles to answer this question!

Weak force

Strong force

Neutralising force

May the force be with you

6.Particles within the nucleus known as protons and neutrons are made up of evensmaller parts. These smaller parts are held together in the nucleus due to the

presence of which of the following? I hope you don't get "stuck" on this question!

Photons

Gravity

7.Atoms are everywhere and they are also the source of radioactivity. The threemost well-known types of radiation are alpha, beta and gamma but from what

language do these letters come?

GreekJapanese

Polish

Swahili


7/178

8.Electrons are a very important part of the atom and are studied heavily in thescience of chemistry. The movement of electrons is responsible for the wonderful

colours of transition metals. On what very famous chemical table can you find the

transition metals?

Periodic table

Octave table

Grouped table

Pool table!

9.The science of physics often aims to simplify things and to unify them into onegreat concept. Which of the following is one example of this where the aim is to

combine the two fascinating fields of general relativity and quantum mechanics? I

have often wondered how long a piece of this is!

String theory

Wool theory

Yarn theory

Space theory

10.As physicists tried harder and harder to find more and more parts of the atomthey ended up with long lists of what they considered "elementary particles". Whatname was given to these numerous "elementary particles" that is now known as the

Standard Model? My oh my! Is that a lion, a tiger and a bear I see?

Sea of particles

Particle mall

Particle zoo

Particle city

Understanding Particles Physics for Kids

1. The correct answer was High energy physicsA great example of a place that scientists collided particles was at CERN. CERN is a French

abbreviation for a nuclear research centre that was founded on the border of France and Switzerland.In their research, they supply large amounts of energy (high energy) to particles so that they move

really fast and bump into each other! They do this to find out what smaller parts are in the atom.

2. The correct answer was Empty spaceNow this really is hard to get to grips with. If an atom is made up of mostly empty space

and we are made of atoms, does that mean we are mostly empty space? Indeed it does and

isn't that just mind-boggling?! Everything you can see that you think is a solid material,such as a wooden desk, is mostly made of empty space.

3. The correct answer was QuarksOK so maybe quack and quark don't sound that similar but it is the best I can do! Quarks

are elementary particles and lots of them together make up protons and neutrons. There are

many varieties of quark and they are rather weirdly called 'flavours'. So if you ever go to aquark milkshake bar you could order one of six flavours, which are: up, down, top,

bottom, charm and strange. I recommend a mix of charm and top, yum!

4. The correct answer was Photon

The photon is a fantastic elementary particle and the road to discovering what a photon

actually is led to many arguments and heated debates amongst physicists! Here we go into

the wacky world of small-scale physics because a photon isn't just a particle and it isn'tjust a wave but it is both. Nonsense you cry! Unbelievably this is true and there are

experiments to prove that light sometimes behaves as a particle and that it sometimes

behaves as a wave.

5. The correct answer was Strong forceNearly everybody when they first learn about protons fails to ask the teacher that if all

protons in a nucleus are positively charged then how does the nucleus keep it shape. The

answer is because there is a strong force present! This is sometimes also known as the

strong interaction or the nuclear force.

Neutrons are also found in the nucleus and along with protons are known as nucleons. These

nucleons are kept together in the nucleus by the magnificent nuclear force.


9/178

6. The correct answer was Gluons

Gluons (just think about glue) are what help to keep quarks, the parts that make up protons

and neutrons, together. They do this by what is known as the color force: again some

physicists were having a bit of fun and decided to call it that despite there being no colorsinvolved at all!

7. The correct answer was GreekThe letters of the Greek language can be found all over the science world. Alpha, beta and

gamma are the first three letters of the Greek alphabet and they each lend themselves toname a specific type of radiation. Radioactivity is both very useful, for example in

medicine, and very dangerous. An example of this is the fact that radiation can cause

cancer but it can also help cure it!

8. The correct answer was Periodic tableThe transition metals are a great way to learn about the nature of electrons. When you first

study the transition metals you learn about orbitals and that electrons can be found

anywhere within these orbitals. This is in contrast to what you first get taught, that electrons"orbit" around the nucleus.

The periodic table contains all the elements that have been discovered and places them in

groups (vertical) and periods (horizontal).

9. The correct answer was String theoryThe aim is to one day have a 'Theory of Everything'. The basic idea behind string theory isthat all types of matter and all forms of energy may be made up of "strings". "Strings" are

a useful way of thinking about these building blocks but it is suggested that the "strings"

are just one-dimensional, meaning the "strings" just have a length. Part of string theory

also suggests that there are many more dimensions than the three (length, width, height)we are used to. It must be stressed however that for the most part, string theory is just an

idea that still needs to be proven.

10.The correct answer was Particle zooThe physicists actually ended up with parts of the atom on their lists that weren't

elementary. The problem of huge quantities of "elementary particles" was solved upon thediscovery of the quark. They realized that most of these "elementary particles" were various

combinations of the six types of quark.

16/178

Geologists

1. One rock is hollow inside, with purple amethyst crystals growing

inside it. What is this called?

The correct answer was Geode

Some of the biggest geodes are 26 feet wide, with crystals three feet long!

2. I have three rocks in front of me. The basalt is hard, dense,

and black. The obsidian is black and glassy. The third rock is

pumice, which is light, frothy, and full of little holes. What

made these three rocks?

The correct answer was A Volcano

Volcanoes spew out melted rock, called lava. The lava can hardeninto different types of rock, depending on how fast it cools. Obsidian

came from lava that cooled very quickly. The basalt came from lavathat cooled more slowly. Pumice comes from lava which is full ofgas, which makes all the holes!

3. The rock where I live is white and chalky. Sometimes it

has fossils of ancient sea shells. What kind of rock is this?

The correct answer was Limestone

Nowadays, limestone forms in tropical places, like the Bahamas.

Limestone dissolves easily in water (over millions of years, of

course). This can make caves.

4. What kind of rock forms when limestone is baked at high

pressure and temperature? Sometimes it is used for carving

sculptures.

The correct answer was Marble

Marble can also be used in buildings. It comes in many differentcolors. Some of the most famous marble quarries are in Italy.

5. What do you call a rock made up of lots of little sand

grains?


17/178

The correct answer was Sandstone

Each sand grain is a tiny piece broken off another rock. Sometimes

you can tell what kind of rock a sandstone came from by looking at

the grains.

6. I have a rock which has big scratches on it, all going the

same direction. I collected it from a place where there was a

great big crack in the rock. Could an earthquake have caused

these scratches?

The correct answer was Yes

Earthquakes happen when rock in the ground breaks and slides pastitself. Earthquakes can make the ground shake and knock down

buildings. They also leave these neat scratches on the break, so we

can tell there was an earthquake there! We call the scratches"slikensides" and we call the break a "fault.".

7. I have a rock that has three kinds of crystals: pink, white,

and black. The pink crystals are the mineral feldspar. The

white crystals are the mineral quartz. The black crystals are

the mineral mica. What kind of rock is this?

The correct answer was Granite

Granite forms deep underground when large pools of magma, or meltedrock, cool.

8. One of the prettiest rocks I have is light grey and

shiny. It also has big red garnet crystals in it. What

is this rock called?

The correct answer was Schist

Schist forms when shale or mudstone is put under high

temperatures and enormous stress, like you would findunder the Himalayas. The heat and pressure causes new

minerals to form, like garnets.


18/178

9. Whenever you go rock hunting, it's a good idea to do some things to make

sure you don't hurt yourself, and you don't annoy other people. Which of these

should you do?

The correct answer was All of these

It's no fun if you get hurt looking for rocks! I'm a grown-up and I get to use a rock

hammer, but I always make sure I wear my safety goggles!

10. There are people who study rocks for a living! I'm one of them. What are

these people called?

The correct answer was Geologists

Geologists can study lots of different things about the earth. A lot of geologists

look for oil, which we use to make fuel like gasoline. Some geologists study

volcanoes and earthquakes, to protect people from them. Some geologists, like

me, study what happens when you make rocks really, really hot and then

smush them! Cool!

Chemistry for Kids

1. One of the most recognisable parts of chemistry is the very helpful periodic table. This table helps

to group certain elements together. One way they do this is by putting things into periods, but what isthe other classification?

The correct answer wasGroups

When the periodic table was set up, it was organised so that a period of elements moved across the

table from left to right and a group moved from top to bottom. If you study chemistry to a moderately

advanced level, you will be taught the reasons for this. A Russian man named Mendeleev devised thetable.

2. Neutralisation is the posh name that chemists give to the reaction between an acid and

a(n) what?

The correct answer wasAlkali

This is one of the first general chemical equations you will learn as a chemistry student!Acid + Alkali (or base) --> Salt + Water. For all you eager young scientists, an acid has a

pH of less than 7 (7 is the pH of neutral compounds) whilst an alkali has a pH greater

than 7.

3. Which of these animals is also the word given to show the chemical amount of asubstance?

The correct answer wasMole

The mole is one the seven SI units used in science. The other six are: the metre, the

kilogram, the second, the ampere, the kelvin and the candela. If you are confused, it would

be an interesting research topic for you! Why couldn't they use the name of an animal thatsounds nicer than the word mole?

4. There are three main states of matter. Solid and gas are two of these, but what is the

third?

The correct answer wasLiquid

Vapour is another word for gas. Solids, liquids and gases are not just important in

chemistry, they are important in all aspects of science. Evaporation is when a substancegoes from being a liquid to a gas. Condensation is when a substance goes from being a gas

to a liquid. There are two further states of matter which you may or may not later learn

about during your education. They are plasma and Einstein-Bose condensate. Just some

extra knowledge for all you budding young scientists!

5. What is the name given to the chemical process in which a substance goes from being

in a solid state straight to being a gas?

The correct answer wasSublimation

Sublimation is where the liquid phase is skipped and a solid substance can be changedstraight into a gas. It can also work in the reverse direction - from a gas straight into a


22/178

solid. A common example of sublimation in action is when dry ice "melts" - it goesstraight from being in a solid state to being vaporous.

6. Which of the following is not part of an atom?

The correct answer wasBlazon

Protons and neutrons are both found in what is called the nucleus (centre) of an atomwhilst whizzing around it are the much smaller electrons. Everything, from you to the

planet Jupiter, is made up of these tiny particles called atoms!

For those interested, a blazon is actually a coat of arms.

7. Elements are substance which are made up of only one type of atom. Which of the

following is NOT an element?

The correct answer wasCarbonate

Elements can be metals or non-metals. Hydrogen is a non-metal and is the simplest of allknown elements. Gold and silver are both precious metals. Carbonate (CO3=) is not an

element because it has both carbon and oxygen atoms in it, which makes it a compound.

8. Even though chemistry can be great fun, it can also be very dangerous. Which of these

should you always wear to protect your eyes in the chemistry lab?

The correct answer was Safety goggles

Goggles (also known as safety glasses) are essential! When you get to college anduniversity level, lab coats become essential as well. In school you should always be very

careful using chemicals and always listen to your chemistry teacher's instructions!

Remember, no one is invincible. Chemicals can be dangerous, so wearing goggles couldsave your eyesight!

9. You are doing an experiment with a substance called hydrochloric acid (HCl) when you

accidentally spill some of it on to your hand. What should you do?The correct answer wasTell a teacher and wash your hands immediately.

If you spill some acid on your hand, don't just wipe it off with your sleeve because that

could damage your clothing and if you do nothing it could cause you harm (acids cause

burns!). Now, technically throwing alkali on it will neutralise the substance but alkali canalso be dangerous to have on your skin, since they can burn your skin too. You MUST tell

your teacher and rinse your hand straight away under running water. Generally, for

younger people the concentrations of the chemicals are very weak and won't be toodangerous, but be prepared just to be on the safe side.

10. OK, you walk into a chemistry lab and your teacher says,'sorry about the smell ofhydrogen sulphide'. What would the smell be similar to?

The correct answer wasRotten eggsThe chemical formula for hydrogen sulphide is H2S. This substance is responsible for a lot

of the foul smells that come out of the chemistry lab. Though, sometimes you can have the

most wonderful of smells. Esters smell like perfume and are also used in yummy peardrops!

we breathe contains lots of different gases such as nitrogen. Less than aquarter of the air around us is oxygen, but that's all we need!

4. What happens if you melt something?

The correct answer wasIt changes from a solid to a liquid

When you melt something, it changes from a solid into a liquid. You can

look at this by watching an ice cube melt. If you put an ice cube on the

sink, it will slowly change from a solid little block of ice into a puddleof water as it melts.

5. Which of these living things does NOT have a backbone?

The correct answer wasEarthworm

An earthworm is one of a number of animals that don't have backbones(spines). Animals without backbones are called invertebrates.


26/178

6. If the moon is full, what shape is it in the sky?

The correct answer wasCircle

When the moon is full, it looks like a circle in the sky. The moon shines

and looks bright at night because light from the sun is bouncing off itssurface.

7. If I dissolve some sugar in water, what have I made?

The correct answer wasA solution

When you dissolve something in something else, it is called making asolution. A cup of tea is a solution too, but I need some tea-leaves to

make that as well as sugar!

8. Planet Earth is the ______ planet from the Sun.

The correct answer wasthird

The Earth is almost 150 million kilometres from the sun! This is just the

right distance - any closer, and it would be too hot for us; any furtheraway, and it would be too cold

9. Which of these is the hottest?

The correct answer wasThe Sun

The surface of the sun is very, very hot - about 6000 degrees Centigrade

(almost 11000 F)! A campfire and heaters are much cooler incomparison. A campfire's temperature is about 200 degrees Centigrade

(400 F).

FUN SCIENCE FOR KIDS

1. What is the chemical formula for water?

The correct answer wasH2O

H2O is the formula for water. This means that it contains 2 hydrogen (H) atomsjoined to one oxygen (O) atom. When atoms are joined together they make a

molecule..

2. What does a caterpillar change into?

The correct answer wasbutterfly

A caterpillar is one of the stages in the life cycle of a butterfly. The

caterpillar eats lots of food then makes a case for itself called a chrysalisand comes out as a beautiful butterfly.

3. What are clouds made of?

The correct answer waswater

Clouds are made of water. When a cloud gets too full of water, it rains.

If it's really cold, the rainwater freezes and this is when we get snow.

4. How many colours are there in a rainbow?

The correct answer was7

There are seven colours in a rainbow: red, orange, yellow, green, blue,

indigo and violet. It's easy to remember the right order by taking the first

letter of each colour and using them to spell ROY G. BIV.

5. If an animal is a carnivore, what does it do?

The correct answer wasit eats meat

Carnivores are animals that eat meat. A tiger is an example of a carnivore.


30/178

6. What does a tadpole turn into?

The correct answer wasfrog

A tadpole is one of the stages in the life cycle of a frog. Frogs belong toa class of animals called amphibians. This means that they can live in

the water or on land.

7. What is the name of the force that holds everything to the

earth?

The correct answer wasgravity

Gravity is what holds us to the earth so we don't all float off into space!

The moon has a lower gravity than earth. If you were to stand on the

moon, you'd be able to jump into the air much more easily since therewould be less force holding you to the ground.

8. If an animal is a herbivore, what does it do?

The correct answer wasit eats plants

Herbivores are animals that only eat plants. A cow is an example of a

herbivore.

9. Which of the following travels the fastest?

The correct answer was light

Light travels at almost 300 million metres (about 950 million feet) everysecond! Sound is the next fastest, travelling almost 350 metres (around

1130 feet) every second. Whew! There are some planes that travel faster

than the speed of sound, but nothing goes faster than light!

10. What do you call a scientist who studies the stars?

The correct answer wasastronomerA chemist is a scientist who studies molecules and the way they behave.

A biologist is a scientist who studies living things. A geologist is a

scientist who studies the earth.

1. Out of all the planets in our Solar System, which one has the most satellites (also

known as moons)?

Your Answer:[No Answer]

The correct answer was Jupiter

According to the latest figures (January 2006), Jupiter has an amazing 63 moons! Saturn is second with

47, and Uranus is third with 27. Mars has two moons - Phobos and Demos.

63% of players have answered correctly.

2. Which element combines with sulphur and oxygen to make sulphuric acid?


The correct answer was Hydrogen

The formula for sulphuric acid is H2S04, which means there are 2 hydrogen, 1 sulphur, and

4 oxygen atoms in the sulphuric acid molecule. Sulphuric acid is the acid used in car

batteries.



34/178

3. In electronics, what does the acronym LED mean?

The correct answer was Light Emitting Diode

An LED is a special type of diode that emits light when a voltage is applied across its little

connections. They are used extensively as "pilot lights", and indicator lights, in a whole

range of electronic equipment and tools.


4. Conjoined twins used to be named after a famous set of twins; what name

used to be given to twins that were joined at birth?

The correct answer was Siamese twins

The name "Siamese twins" is attributed to Chang and Eng Bunker, who lived from 1811 to1874. Conjoined twins, to give them their more technical name, are born with their bodies

physically linked, and have intrigued and amazed people for centuries. There are only a few

who have survived unseparated into adulthood. Some have described their experience, but it

must be impossible to imagine what it is like to have such an intimately shared existence,joined to another human being 24 hours a day.


5. If a metal or alloy is termed non-ferrous, what essential property does ithave?


The correct answer was Does not contain iron

The ONLY property that determines if a metal or alloy is non-ferrous is the fact that it does

NOT contain iron. Both ferrous and non-ferrous metals can be magnetic or non-magnetic,some resist corrosion and others don't.


6. Theoretically, if an engineer built an infinitely long bridge, perfectly flat,

perfectly level, and perfectly straight - what would it appear to do?


35/178


The correct answer was It would slope up from the ground

When a very long bridge is constructed, it is NOT built perfectly flat. It actually has to have

a very slight curve downwards - to account for the curvature of the earth! Theoretically, if

an infinitely long bridge was built perfectly level and straight, it would rise up eventuallyinto outer space!


7. Which of these metals melts at the lowest temperature?


The correct answer was Lead

Lead melts at 327C, aluminium melts at 660.25C. The melting point of copper is a littlehigher than gold.

Lead has numerous uses in industry; it used to be used for domestic water pipes until it wasrealised that it is poisonous!


8. What is added to glass to give it an intense deep blue colour?


The correct answer was Cobalt oxide

Blue glass is manufactured by the addition of cobalt oxide. Many different colours of glass

can be made by adding different metals and/or oxides. Red glasses are made with gold,copper, or selenium oxides, and one part of nickel oxide in 50,000 produces a tint that may

range from yellow to purple, depending on the base glass.


9. In the physical sense, what is the definition of a perfect vacuum?


The correct answer was A space containing absolutely nothing


36/178

A perfect vacuum exists ONLY when a space contains absolutely nothing at all. If a spacecontains so much as ONE atom, it is NOT a perfect vacuum. Even in outer space where

there is no air, a total vacuum is not as common as you may think, because even outer space

contains dust.


10. At around what age do our bones actually stop "growing", and therefore atwhat age do we start to degenerate into old age?


The correct answer was 28

Our skeletal bones are not totally "set" or ossified until we reach the age of around 28, so

until that time we are actually still growing. Scientists are able to tell the age of a skeleton

from the amount of ossification in the bones. Most of the cells in our body are replaced

when old ones die, so in one sense we never stop growing. Metabolic changes start to occurthough at around age 28, and our bodies actually start to "slow down", so unfortunately we

start to "grow old".

1.OK, first of all, we're off to the chemistry lab! We learn all about the propertiesof elements and compounds. Our teacher asks us what two elements common table


37/178

salt is made out of. What ARE they?

Sodium and Hydrogen

Sodium and Chlorine

What ARE they?

Hydrogen gas and carbon dioxide

Methane gas and nitrogenWater and a salt

Water and ethanol

6.So, we're about to go to our biology class, but wait, we forgot our physics books!So, going back to our physics classroom, Mr. Jimmy asks us what stored energy is

commonly called. What IS it?

Potential energy

Kinetic energy

Chemical energy

Radiant energy

7.So, we arrive at Mrs. Diane's biology class and learn loads of stuff! She asks us

what measurement unit microbiologists use when they want to measure something

really small (like a bacterial cell!). What IS it?

Millimeter

Meter

Centimeter

Micrometre

8.Next class is environmental science! We learn all about greenhouse gases and theincreasing danger they can do to the enviornment. The teacher asks us what is NOT

a greenhouse gas. What IS it?

Carbon dioxide


39/178

Nitrogen

Methane

Ozone

9.OK! Next we must go back to our botany class! Our teacher asks us which class ofmetaphytan plants contain flowers. What class IS it?

Gymnospermae

Angiospermae

Tracheophyta

They all have flowers!

10.It's the last class of the day! We learn all about the human body. We learn aboutthe organs and their functions. Mrs. Waters asks us what system our brain is in.

What IS it?

Nervous system

Digestive system

Circulatory system

Respiratory system

1. OK, first of all, we're off to the chemistry lab! We learn all about the properties of

elements and compounds. Our teacher asks us what two elements common table salt is

made out of. What ARE they?


The correct answer was Sodium and Chlorine

Table salt (sodium chloride) is made out of the elements sodium and chlorine. It is made up of oneatom of each. Its chemical formula is NaCl. A little salt is needed for all human beings, but too much

salt can lead to problems, like high-blood pressure.


40/178


2. Next, we're going to observe the microscopic world! We find all sorts of

interesting infomation. After being lectured about all the the different functions

of the organelles of the cell, our teacher asks us what organelle is known as the

'brain' of the cell. What IS it?


The correct answer was Nucleus

The nucleus controls all the reactions within the cell. The chloroplast is the organelle in

plant cells where photosynthesis (where radiant energy from the sun is converted to

chemical energy) takes place. It contains pigments known as chlorophyll. Chloroplasts areonly found in plant cells. The mitochondria is where respiration occurs. All cells (not just

plant cells) contain mitochondria. All cells also have a cell-membrane. This selectively

allows some materials to pass, and not others, such as starches.


3. Next, we go on to our botany class. We learn all about plants and the

amazing photsynthetic processes they undergo! After the lectures, our teacher

asks us what gas plants contribute to the earth's atmosphere. What IS it?


The correct answer was Oxygen

Plants keep the oxygen content stable by photosynthesis. They release oxygen gas into the

atmosphere as a by-product of photosynthesis. Denitrifying bacteria contribute to the vast

amount of atmospheric nitrogen in the atmosphere (78% of the earth's atmostphere isnitrogen). Carbon dioxide is needed for photosynthesis, but isn't released into the

atmosphere by photosynthetic processes.


4. Right before lunch, we're off to physics. Mr. Jimmy, our physics teacher asks

us what the main particles of an atom are. What ARE they?



41/178

The correct answer was Neutron, electron, and proton

The proton has a postive charge, the neutron has no charge, and the electron has a negativecharge. The electrons are on the outer orbit of a atom. A covalent bond exists when

electrons are shared between atoms. This is the most common form of chemical bonding.

All matter is made out of atoms. Chemical elements contain only one type of atom. All thechemicals in a cell are made out of atoms, so atoms must be VERY, VERY tiny indeed!


5. After lunch, we must go back to chemistry class. Our teacher asks us what

products are, as a general rule, the result of an acid and a base reacting together.

What ARE they?


The correct answer was Water and a salt

Whenever an acid and base combine, they almost always produce water and a salt.

However, water and carbon dioxide are occasionally produced. You have probably heard of

the volcano experiment! Well, when you mix baking soda (a base) and vinegar (an acid)together, the end products are water and carbon dioxide. However, it is mostly water and a

salt (such as sodium chloride) that are produced in this type of reaction.


6. So, we're about to go to our biology class, but wait, we forgot our physics

books! So, going back to our physics classroom, Mr. Jimmy asks us what stored

energy is commonly called. What IS it?


The correct answer was Potential energy

Potential energy is stored energy. Kinetic energy is moving energy. Radiant energy is the

energy the sun gives off! Chemical energy is the energy created by a chemical reaction.


7. So, we arrive at Mrs. Diane's biology class and learn loads of stuff! She asks

us what measurement unit microbiologists use when they want to measure


42/178

something really small (like a bacterial cell!). What IS it?


The correct answer was Micrometre

To get a micrometre, you multiply the amount of millimeters by a 1000. So, if the answer in

millimeters was 3, it would be 3000 in micrometres! A micrometer is one millionth of ameter - very, very small!


8. Next class is environmental science! We learn all about greenhouse gases and

the increasing danger they can do to the enviornment. The teacher asks us what

is NOT a greenhouse gas. What IS it?


The correct answer was Nitrogen

Nitrogen is NOT a greenhouse gas, however nitrous oxide is. Greenhouse gases contribute

to global warming. Deforestation is a big contributer to the greenhouse effect.


9. OK! Next we must go back to our botany class! Our teacher asks us which

class of metaphytan plants contain flowers. What class IS it?


The correct answer was Angiospermae

All plants in the class Angiospermae contain flowers! These flowers attract insects andother small organisms to carry their seeds. In this mutualistic relationship, the plants get

their seeds distrubuted within the area leading to diversity. In return, the animals get fed

with the fruit that the plants contain. Gymnosperms do not contain flowers. Both

gymnosperms and angiosperms belong to the phylum Tracheophyta. Because it is not aclass, but instead a phylum, that is not the right answer!


10. It's the last class of the day! We learn all about the human body. We learn


43/178

about the organs and their functions. Mrs. Waters asks us what system our brain

is in. What IS it?


The correct answer was Nervous system

The nervous system contains the brain. The circulatory system contains the heart. Thedigestive system contains the small and large intenstines. The respiratory system containsthe lungs and all the organs that help us breathe! We need all these organ systems to

survive! I really hope you enjoyed my quiz! I hope you learned LOADS of new infomation!

True

False

10.Black holes can be formed when a star collapses under its own gravity.

True

False

1. Life didn't start on Earth as soon as it was formed. Why?


The correct answer was Conditions weren't good enough

Nothing lived on Earth for the first billion years of the planet's existence. The conditions were not rightfor life. There were no plants or animals of any kind. At the time, Earth was a dangerous place wherelife could not survive.


2. What's moving the continents?


The correct answer was Magma underneath the Earth's crust

The continents move about one and a half inches a year - about the length of your pinkie.


46/178

Millions of years in the future, Earth will look very different from today.


3. Where did life on Earth first begin?


The correct answer was In the ocean

Life on Earth began about 3.5 billion years ago. It was born into a world that looked very

different to today. The atmosphere was filled with poisonous gases, the sky was pink, and

the sea was rusty red.


4. Earth has one moon, named Luna. Luna changes phases because it istravelling around the Earth. Which of the following is one of the shapes the

moon appears to us as?


The correct answer was Crescent

First it looks like a banana (thin crescent), then a sideways laugh (wider crescent, for some

areas), then a circle, then it does this all all over again but backwards!


5. Is the Earth flat?


The correct answer was No

The Earth is not flat. Early explorers thought it was though! They thought if they sailed toofar, they would fall off the edge. It was up until Galileo Galilei found this out. He also foundout that the Earth wasn't at the center of the universe.



47/178

6. What is one of the characteristics of life?


The correct answer was Responding to your Environment

Some other characteristics of life are: waste production (metabolism), growth, and

reproduction. Wondering why I chose response to environment? Living things flinch, getscared, or get hurt. When you touch a cactus and get pricked, you are responding by pulling

your hand away. Non-living things won't do this. Have you ever jumped when you got

scared? That is your body responding to the "scary" thing.


7. What were the very first fish?


The correct answer was Jawless fish

Instead of jaws to open and close their mouths the very first fish sucked food into their

mouths. They are called jawless fish. They looked like they had just sucked on a lemon!


8. What is the name of the ocean between North America and Europe?


The correct answer was Atlantic Ocean

The Atlantic Ocean can be bitterly cold...but think about the Arctic Ocean! Did you know

the luxury ship Titanic sank in the Atlantic Ocean in 1912?


9. Dinosaurs were the first life form to appear on land.


The correct answer was False


48/178

About 440 million years ago, the first life appeared in the ocean. It was simple plant life,similar to today's mosses. Then, about 400 million years ago, the first land animals - worms,

spiders, scorpions and insects - evolved as they moved onto land, then came the dinosaurs.


10. Black holes can be formed when a star collapses under its own gravity.


The correct answer was True

A black hole is a star that has been incredibly compressed to the point where it collapsesunder its own gravity. The atoms get squeezed together, so it's a bit like taking snow and

squishing it until it turns into hard ice. One teaspoon of a black hole would weigh about 10

tonnes, and gravity is so strong that light cannot escape. That's why they're black.

The correct answer was Nitrogen

Too easy? These use the first letter of the element. Nitrogen (N) is a gas that makes up about 78% of


51/178


52/178

common names. You may want to look at a Periodic Table of the Elements for

these. What heavy grey metal has the symbol Pb?


The correct answer was Lead

Lead takes its name from plumbum, a Latin word. Plumbers are called that because theyused to work with lead pipes. Cobalt is Co, chromium is Cr and copper is Cu (also from aLatin word - cuprum).


6. What is the symbol for sodium?


The correct answer was Na

Sodium takes its name from the Latin natrium. It explodes if placed in water, so is usually

stored in kerosene. Combine sodium (Na) with chlorine (Cl) and you get the compound

sodium chloride (NaCl) or table salt. S is sulphur, which shows why it can't also be sodium.


7. What is the symbol for silver?


The correct answer was Ag

Another Latin one - argentum. Argentina was named for this because silver was mined

there. S is sulphur and Si is silicon.


8. Which of these is not an element?


The correct answer was Carbon Monoxide


53/178

Carbon monoxide is a compound with formula CO, made up of carbon (C) and oxygen (O),both elements. Platinum is an element with symbol Pt. Carbon monoxide is a poisonous gas

produced in car exhausts.


9. What metallic element has the symbol Au?


The correct answer was Gold

Gold has the symbol Au from the Latin aurum, meaning gold. Iron is Fe from Latin ferrum,nickel is simply Ni, and zinc is Zn.


10. My personal favourite element has the symbol Hg. What is it?


The correct answer was Mercury

Mercury takes its symbol from the Latin hydrargyrum or quicksilver. Like the fast planet

Mercury and the Roman winged messenger of the gods, it is 'quick', and impossible to pickup if you spill it. (Careful, it's also poisonous!)

Hydrogen, the lightest element, is H. Helium (2nd lightest) is He and hafnium is Hf.

10.According to Einstein, time travel into the future is possible.

True

False

1. Which of the following is the biggest?



56/178

The correct answer was Atom

Protons, neutrons and electrons are the main particles found in atoms. Protons and neutrons are muchbigger than electrons - they are more than 1,800 times heavier.


2. Which of the following has the highest viscosity?


The correct answer was Syrup

Viscosity is a measure of how a liquid flows. When you pour water into a glass quickly, it

flows easily and fills the glass quickly. If you try the same thing with syrup, it flows muchmore slowly. Syrup is a thicker liquid than water and has a higher viscosity.


3. About how much of the Earth does water cover?


The correct answer was three quarters

Water covers nearly three-quarters of our planet. Water is vital to the survival of life onEarth. It is unlike most other substances because on Earth it exists in all three states of

matter (solid, liquid and gas) all at once.


4. What is the force called that water gives you which helps you float?


The correct answer was Upthrust

When a ship goes into the water, it floats, but did you ever wonder that how does such a

heavy ship float? When the ship goes into the water it displaces a lot of water, so it gets a lot

of upthrust helping it to float.


57/178


5. One thing that can't travel through a vacuum is sound.


The correct answer wast

Sound is carried by waves made by vibrating molecules. In a vacuum, there are no

molecules and therefore no sound.


6. What language did the word electricity come from?


The correct answer was Greek

The word "electricity" comes from the Greek word for amber -

"elektron". If rubbed with wool or fur, amber becomes electrically charged and can attract

light objects.


7. Complete the following sentence: ______ electricity causes lightning strikesand makes some clothes crackle as we take them off.


The correct answer was Static

Electricity does not always move; however, static electricity causes lightning strikes and

makes some clothes crackle as we take them off. Objects can develop a positive or negative

charge when they rub against each other.


8. Complete the following sentence: On Earth, the main source of light is

_____.


58/178


The correct answer was The Sun

On Earth, the main source of light is the Sun. Nuclear reactions at the core of the Sun create

energy in the form of light and heat. A few organisms, such as fireflies and glow-worms,

produce natural light in their bodies through a chemical reaction called bioluminescence.

1. When an electrical charge jumps from one place to another, what is it called?


The correct answer was spark

When you rub certain materials together, it can cause a buildup of electrical charges on their surfaces.

Opposite charges attract and similar charges repel. Either of these charges can move to something witha neutral charge. Sparks occur in the extreme case of electrons being attracted to an object with a

positive charge.


2. Meat, milk, and eggs are important for providing what in our diet?


The correct answer was protein

Other protein sources are fish, cheese and tofu. Protein supplements like whey protein areanother way to supply the protein you need.


3. Of the following, what is the correct order of development?


The correct answer was fertilized egg, embryo, fetus

An organism in the early stages of growth goes through these stages. In higher forms it

moves into fetal stages but in lower forms it ends in the larval form of life.

4. What is the name of the liquid food that bees get from plants?


The correct answer was nectar

Bees don't collect honey. Nectar and other sweet deposits from plants are made into honey.

It is modified and stored in the honeycomb by honey bees.Bees collect pollen as well and carry it back to the hive where it is used as a protein source

during brood-rearing.


5. Which of these is NOT a crystalline solid?


The correct answer was glass

A crystal is a solid in which the atoms, molecules, or ions are packed in a regularly ordered,repeating pattern in all three spatial dimensions. Technically, glass is inorganic, created by

fusion and cooled to a solid condition without crystallizing.


6. The elliptical (oval-shaped) orbit of Pluto sometimes brings it even closer to

the sun than what other planet?


The correct answer was Neptune

Each revolution brings Pluto closer to the sun than Neptune for about a 20 year period but

for most of its orbit, Pluto is further away from the sun than Neptune. Pluto is now definedas a dwarf planet of the Solar System.

It's different for every magnet

Clockwise

From north to south

10.Where are the field lines most concentrated around a bar magnet?

At the centre.

At both poles.


69/178

At the South Pole.

At the North Pole.

1. When talking about magnets, what word is the opposite of attract?


The correct answer was Repel

Magnets can attract and repel depending on the position of the magnetic poles. Remember, like poles

repel and opposite poles attract.


2. If you hang a magnet so it is free to swing and turn, what have you created?


The correct answer was Compass

Chinese sailors did this a long time ago to invent the compass. The north pole of the magnet

is the part of the magnet that points towards the north pole of the Earth.

A flux capacitor is the thing in the 'Back to the Future' movies that is used to time travel.


3. If I bring a North and South Pole together which word or phrase best

describes what happens?


The correct answer was Attraction

The magnet repels when two like poles are brought together. It attracts when two opposite

poles come together. Maglev trains (magnetically levitated trains) use magnetic repulsion to"float" above the track.


4. Which pole of a magnet in a compass points north?


70/178


The correct answer was North Pole

Therefore, the North Pole on Earth is actually a magnetic South Pole and the South Pole is a

magnetic North Pole. Remember that opposite poles attract each other.


5. What advantage does an electromagnet have over a permanent magnet?


The correct answer was An electromagnet can be switched off.

This turning off of an electromagnet is used in junk/scrap metal yards throughout the world.

After the cranes pick up metal they can then turn the electro-magnet off and drop the metalwhere it is needed.


6. How can an electromagnet be made stronger?


The correct answer was All of these answers are correct.

A wire with an electric current running through it has a small magnetic force, and thecoiling of the wire increases this magnetic force. The iron core may become a permanent

magnet when the electricity is turned off, depending on how hard the iron is. 'Soft' iron loses

its magnetism very quickly when the current is turned off.


7. Which of these devices uses a magnet or electromagnet to make it work?


The correct answer was An electric bell

When the circuit is complete, the electromagnet is turned on; however this electromagnet

pulls the contacts apart and breaks the complete circuit. A spring then pulls the contacts


71/178

back together and the circuit is complete again.


8. Which of these metals are attracted to a magnet?


The correct answer was All of these.

These are three basic metals that are attracted to a magnet; remember that their alloys are

also attracted e.g., steel is an alloy of iron and is therefore attracted. There are also some

new ceramic materials that exhibit magnetic properties.


9. In which direction do the field lines go around a magnet?


The correct answer was From north to south

This can be shown using small plotting compasses. Place them around your magnet and

they will give you an outline of the field lines around the magnet. If you're using an electro-

magnet, reversing the current will make the field lines go in the opposite direction.


10. Where are the field lines most concentrated around a bar magnet?


The correct answer was At both poles.

Sprinkle some iron filings around a magnet and they take the shape of the magnetic field.

You will notice there are more field lines at the poles.

10.What is the gas found in a fart that produces the smelliest of farts?

Hydrogen

Nitrogen

Carbon dioxide

Hydrogen sulphide

1. From which of the following do we get aluminium?


The correct answer was Bauxite

Bauxite is the main ore of aluminium, and is where we get over 99% of metallic aluminium. Bauxite isa mixture of similar minerals that contain hydrated aluminium oxides. These minerals are gibbsite,

diaspore, and boehmite. Because it is a mixture of minerals, bauxite is a rock, not a mineral.


2. Sugar contains more calories per gram than fat.


The correct answer was f

All proteins and all carbohydrates (sugar is a carbohydrate) have 4 calories per gram, and allfats have 9 calories per gram, but not all foods have the same number of calories per unit of

volume. A cup of chopped cucumber would contain around 14 calories, but a cup of raisins

would contain about 520 calories - they are both carbohydrates, but raisins have a muchgreater calorie DENSITY.
