Task 2: Comprehension task.

Read the following passage and then answer the following questions.

Science is an exciting subject, where you can do

experiments and work in a laboratory. But what is

science? What will you learn in science lessons?

Science is two things at once.

1. Science is doing experiments. Experiments

are a way of finding answers to problems.

You will also learn a lot from doing your

own experiments.

2. Science is knowledge. It can include what

your teacher tells you, what you learn in

books or magazines, or the Internet.

People whose career is studying science are called

scientists. Science and scientists are everywhere. It

can be commonly found in a laboratory, hospital,

research facility, national park, naval ship, building

site and beauty salon.

Many scientists study one part of science. We say

that they specialise in that part. Such a person

may become specialised in that part. Such a

person may become a specialist in that field. Areas

of special study have special names.

Biology is the study of living things. A person who

specialises in this study is called a biologist.

Chemistry is the study of chemicals and how to

change them, and is studied by a chemist.

Physics is the study of energy, matter and

movement and is studied by a physicist.

Geology is the study of rocks and the earth, and is

studied by a geologist.

Ecology is the study of how plants and animals

interact together in the environment, and is

studied by an ecologist.

Astronomy is the study of planets, stars and the

universe, and is investigated by an astronomer.

Some scientists only study one aspect of their

chosen science. For example, a biologist could

become a specialist in the study or birds, whales,

reptiles, plants, microbes.

Some people pretend that they are scientists.

These studies are called pseudo-science. Pseudo

(‘soo-doe’) means false. A common example of a

pseudo-science is astrology, the prediction of your

future by looking at the positions of stars and

planets.

Australia has a long tradition of producing

extremely talented scientists such as Adrienne

Clarke, Andy Thomas and Howard Florey. Many of

our scientists have been awarded the Nobel Prize,

the highest science honour in the world.

b) What was he trying to do?

___________________________________________________________________________________

c) What did he do wrong?

___________________________________________________________________________________

d) How should Sean have checked the test tube safely?

___________________________________________________________________________________

In Science we must ensure we think about any risks to safety before completing an experiment. This allows

us to possibly modify our Method or use things like Personal Protective Equipment (PPE) to minimise or

prevent harm. When we write our practical report we list the safety risks and the prevention measures in a

table like the one below:

Risk Prevention measure

Chemicals spilling on body or lab Wear correct PPE including lab coat, leather top shoes and safety glasses. Follow the instructions of the teacher.

Bunsen burner causing damage to body Wear hair tied back, use correct technique and follow instructions of the teacher. Never leave a lit Bunsen burner unattended.

Task 3: Drawing scientifically

Scientists have a quick and simple way to draw observations. Using scientific drawings means you don’t

have to be an artist to be a good scientist and you have more time to do the experiments.

The procedure for drawing scientifically is as follows:

1. Look at the specimen carefully and examine the significant features that will be included in the drawing.

2. DRAW ONLY WHAT YOU SEE!! Do not include what you think you should see 3. Draw clearly and neatly. Always use distinct, single lines when drawing. 4. Always use a sharp pencil. 5. Draw the equipment in 2D. 6. Do not show any detail, just a simple outline with no shading. 7. Draw lines with a ruler. 8. Print labels neatly and connect them to the diagram with a line or arrow. 9. Spell labels correctly 10.Diagrams should be between 4 and 8cm high. 11.No more than two drawings should be on a single page.

Some examples are shown below:

Task 2: Observations

Read the following information and complete the questions

In science, we need to make a lot of careful observations. Observations are what we can say about things

we see, hear, smell, taste and touch. We can also use measuring equipment to help us with observations.

How would you describe a platypus to someone who had never seen one before? Some observations could

be:

It has a bill like a duck and webbed feet.

Its fur feels smooth

It tastes like kangaroo

It sniffs like a dog

The one we measured was 32 cm long.

When a platypus was first sent to Europe, the scientists

who saw it thought the people in Australia were trying to

play a trick on them.

They believed the people in Australia had sown a duck’s

beak on a beaver. They didn’t take the time to make good observations.

Some statements that are not observations are:

It has a duck’s bill sown on to it.

It is a type of dog

It must be a marsupial

It probably is able to swim.

1. Why didn’t English scientists believe that the Platypus was a real animal?

_____________________________________________________________________________

_____________________________________________________________________________

2. Why are the statements ‘it probably is able to swim’ and ‘it is a type of dog’ not observations about

the platypus?

_____________________________________________________________________________

_____________________________________________________________________________


Task 3: Observation

Riddle of the face on Mars Is there really a face carved on the surface of the planet Mars? Or is it just a group of shadows made by mountains and valleys? The answer to this question was only found after many careful observations were made. These observations were made using telescopes and cameras on board surveyors and probes. We can make observations using our sense of sight, hearing, touch, taste and smell. If there were a face on Mars, how did it get there? This observation leads to many inferences. An inference is a possible explanation for what is observed. Perhaps the face was carved by a lost Martian civilisation. Maybe it is just an optical illusion. Or maybe it is a rock formation which has formed naturally.


A. Cloning around A geneticist tried to clone a giant yabbie. The two yabbies which grew are pictured below. They are not identical as the geneticist first thought. Look carefully at the two yabbies and list as many differences as you can.

B. When we make observations we need to describe what we see, hear, feel, taste or smell in a clear

and complete way so the person reading the observations can make an accurate picture in their mind.

Compare these two sets of observations made of the same object Observation 1: It is small, long and thin with a pointed end. It is red, brown and grey. The object is hard and soft. It feels rough and smooth.


Observation 2: The object is 15cm long and 0.5cm wide. It is shaped like a cylinder but has a pointy end. It is made of two types of materials. The outside material is light brown and it has a red coating over it. The inside material is dark grey. The outer material is harder than the grey inner material. The outer material feels dry and rough. The inner material feels smooth and greasy. What do you think the object is? ___________________________________________________________ Which observation is better? _______________ Why? __________________________________________ _______________________________________________________________________________________

Week Eight

Task 1: Observations and inferences We often try to explain what we observe. Whatever you think after you make an observation is called an inference. An inference is one possible explanation for what you have observed. For example: You go to water your favourite plant. OBSERVATION- some leaves have holes in them or parts missing INFERENCE- an insect has been eating it It is very important that you can tell the difference between an observation and an inference. Look at the diagrams on the following page. Write an observation and an inference for each diagram in the table.

Task 2: Inferences When people make the same observation they can explain it in different ways. It is possible to make many inferences from the same observation.

Dead fish are found floating in the stream near Elderslie High School. Three inferences are listed in the table below.

1. Write down two inferences of your own in the table which could explain the dead fish. 2. For each inference write an observation in the table which would support or help prove it correct. 3. For each inference write an observation in the table which could disprove it.

The first one has been done for you as an example.

Inference Observations to support inference Observations to disprove inference

1. Fish have been dumped into the stream by a local resident angry over the location of a new rubbish tip.

The dead fish were not the type of fish normally found in the stream.

Many other water creatures were found dead or dying along the stream.


2. The fish were poisoned by pesticide sprays drifting into the stream from the nearby apple orchard.

3. The fish died when the water temperature increased due to the waste water released by the factories.

Task 3: Making logical inferences Read each of the passages and write answers to the questions which follow in the space provided. A. Five students went to sick bay in the afternoon all with stomach cramps. Each student had purchased their lunch from the school canteen. The school nurse asked each one to write down what they had eaten that day.

- Student 1 had eaten toast with butter, a meat pie, an apple, a custard slice and a flavoured milk. - Student 2 had eaten weetbix with milk, an orange, a salad roll and a custard slice. - Student 3 had eaten custard slice and a can of Fanta. - Student 4 had eaten a chicken sandwich, a custard slice and an orange juice. - Student 5 had eaten scrambled eggs with toast, a banana, a chocolate muesli bar, a sausage

roll, a custard slice and a milkshake.

Task 1: Measuring- optical illusions

Optical illusions are drawings designed to trick your eyes. In this task you will make measurements in order to make more accurate observations.

1. Examine diagrams (i) to (v) carefully 2. Make a measurement to find the correct answer to each question 3. Explain how your sense of sight may have been tricked

Diagram Question Measurement Explanation

Which telegraph pole, A or B, is longer?

Which line, A or B, is longer?

Which circle, A or B, is wider?


Is the hat taller than it is wide?

Which line, A or B, is longer?

Task 2: Measurement You may need to use additional resources, such as an adult, internet or textbook, to complete the following task.

1. All measurements are made up of two parts: i. a number ii. a unit

Each quantity is given a base unit which can be written as a symbol. Complete the missing information in the table.

Quantity Base unit Symbol

Length Metre m

Mass kg

Task 3: Averaging Measurement No matter how much care we take when we are making measurements, it is still possible to get a range of values for something. For example: a beaker was weighed three times and its mass recorded as 78.9g, 79.3g and 78.8g. We cannot say that any of these measurements are better than another. The best measurement to use will be an average of the three results. Step 1: Find the total of all the measurements: 78.9 + 79.3 78.8 Total 237.0 Step 2: Divide the total by the number of measurements: Total = 237.0 = 79.0g Average = number of measurements 3 The average mass of the beaker is 79.0g. The more measurements that are made of a quantity, the better or more reliable the average will be.


1. For each of the following, determine what is being measured (eg mass, length, time, temperature), and then calculate the average. a. 6cm, 7cm, 12cm

___________________________________________________________________________ b. 10g, 15g, 16g, 17g

___________________________________________________________________________

c. 60s, 55s, 35s, 70s ___________________________________________________________________________

2. What is the unit for measuring: a. Mass? _____________________

b. Time? _____________________

c. Temperature? ______________

3. It is easy to change one metric unit into another. However, you must be able to multiply and divide by the numbers 10, 100 and 1000. Complete the missing spaces for converting measurements. The first one has been done for you.

Number Unit Equals Number Unit

1 kilogram = 1000 grams

1 centrigram = 0.01

gram = 0.001 kilograms

1 milligram = grams

1000 = 1 000 000 kilograms

1000 micrograms = gram

100 = 1 gram
