WEATHER EVENTS “I wonder how much snow will fall this winter”

“I had to stay inside all day because of the storm!”

“Nice weather we’re having!”

Weather affects us every day. Weather is different all over the world - some countries have

hot climates, some have cold climate, and some are in between. Weather affects the decisions

we make, where we live, and what we can do. Weather is made up of many different things,

including wind direction, wind force, temperature, sunshine, visibility, cloud and precipitation.

There’s so much to explore when we look at the weather.

EXTREME WEATHER

Extreme or severe weather is simply really bad weather or weather on a larger, more serious

scale.

For example:

Instead of a few snowflakes falling, there is a snowstorm and snowdrifts

can be many meters deep.

Extreme forms of a windy day include gales, cyclones and

tornadoes.

Heavy rain may last much longer than a few hours or even days and

result in flooding of rivers, roads and homes. Extreme weather events

may not happen very often. When they do they can cause destruction of

buildings, vehicles, roads and homes, costing many billions of dollars.

People’s lives are also at risk from some unexpected weather events. Modern technology

allows predictions to be made so people know when and where a cyclone is going to hit land.

However, some storms, including tornadoes, still cannot be forecast accurately.

LANGUAGE ACTIVITIES

EXTREME WEATHER WORDS

Present the following words to your child and ask them to tell you words which describe each

weather event. Suggested answers are in the brackets. Word lists could be written to

describe each event. They could also be illustrated by your child.

Thunderstorm( rain, clouds, lightning, thunder, wind)

Tornado (clouds, strong wind, rain, hail)

Hurricane or cyclone (strong wind, heavy rain)

Blizzard (heavy snow, ice, cold temperatures)

Dust storm (strong winds, arid conditions)

Flood (heavy rainfall)

Hail storm (cold or warm temperatures, rain, ice)

Ice storm (freezing rain)

FORCES OF NATURE MAZE WORKSHEET

Directions: Guide the rain to the tornado.

WIND

WIND EXPLORATION

In this activity, kids can feed their curiosity by

exploring wind - both the kind they make by

blowing through a straw and the naturally occurring

wind that moves a pinwheel!

What you’ll need:

2 or more large, wide tubs to hold material

for wind observations (something similar to a large dish tub would be ideal)

Fill one tub with water

Fill one tub with sand, bird seed or similar substance

Straws

Crayons or colored pencils to color in the the pinwheels

Safety scissors to cut out the pinwheels

Pencils with erasers

Drawing pins to secure the pinwheels to the pencils

WIND ACTIVITY

Hand kids straws and have the children blow through the straws on to their hands

Ask them what that feels like

Can they make the force of the “wind” stronger by blowing harder?

Have the children blow through the straws into the tubs to see how the force of the wind

affects the different materials.

Float an object on the water and have them blow on

the object.

How does the wind affect the object?

Talk to them about the role the wind plays in the environment.

Why do they think wind is important?

You may want to give them hints to think about things like Dandelions and clouds to discuss how the wind is

important for things like seeds and the weather

PINWHEEL ACTIVITY

How to Make a Pinwheel

You will need:

Several pieces of scrapbook or strong paper cut into

10cm squares

Drawing Pins

Pencils with eraser tops

Scissors

Directions

Encourage your child to color the pinwheel before folding or cutting.

First, fold a piece of paper diagonally. Keep your paper folded in a triangle. Fold it

again, into a smaller triangle.

Now unfold the paper, so it looks like a square. Your paper will have crease lines in an

“X” shape.

Cut about 3/4 the way up towards the center of the paper on each fold line.

Bring each corner with a hole in it towards the center of the paper. You will start to

see the pinwheel shape taking form.

Once you’ve gathered all of the corners to the center, put the pin through the center to

hold them down.

Finally, press the pin into the eraser on top of the pencil to attach your pinwheel to its

handle.

Is the pinwheel spinning? What’s making it spin?

Can you make the pinwheels spin faster or slower?

CYCLONES

What is a cyclone? A cyclone is a huge storm! Hurricanes, cyclones, and typhoons are all the same weather

phenomenon; we just use different names for these storms in different places. It can be up to

1000 kilometres across and have strong winds spiraling inward and upward at speeds of 120 to

300 kph.

Each cyclone usually lasts for over a week, moving 15-30 kilometres per hour over the open

ocean. Cyclones gather heat and energy through contact with warm ocean waters. Evaporation

from the seawater increases their power.

Cyclones rotate in clockwise direction in the

Southern Hemisphere and an anti-clockwise

direction around an "eye" in the Northern

Hemisphere.

The center of the storm or "eye" is the

calmest part. It has only light winds and fair

weather. When they come onto land, the

heavy rain, strong winds and large waves can

damage buildings, trees and cars.

How Do Cyclones Get Their Names?

Short, distinctive names for cyclones in written and spoken communications are quicker and

less likely to be mistaken, unlike the older more cumbersome latitude-longitude identification

methods.

In Australia, the name of a new tropical cyclone is usually selected from a list of names. If a

named cyclone moves into the Australian region from another country's zone of responsibility,

the name assigned by that other country will be retained. The names are normally chosen in

sequence, when the list is exhausted, the Bureau of Meteorology returns to the start of the list.

When a significant cyclone affects Australia (like TC Tracy in 1974 or TC Larry in 2006), the

name is "retired" and replaced in the list with a name of similar initial and gender.

THUNDERSTORMS

What is a thunderstorm?

A thunderstorm is a storm with lightning and thunder.

It is produced by a cumulonimbus cloud, usually producing

gusty winds, heavy rain and sometimes hail.

What causes a thunderstorm?

The basic ingredients used to make a thunderstorm are

moisture, unstable air and lift. You need moisture to form clouds and rain. You need unstable

air that is relatively warm and can rise rapidly. Finally, you need lift. This can form from fronts,

sea breezes or mountains.

When are thunderstorms most likely to occur?

Thunderstorms can occur year-round and at all hours.

They are most likely to happen in the spring and summer months and

during the afternoon and evening hours.

How many thunderstorms are there every day?

It is estimated that there are around 1,800 thunderstorms that occur across our planet every

day.

MAKING THUNDER!

Materials:

Brown paper lunch bag

Process:

Blow into the brown paper lunch bag and fill it up with air.

Twist the open end and close with your hand.

Quickly hit the bag with your free hand.

Explanation:

Hitting the bag causes the air inside the bag to compress so quickly that the pressure breaks the bag. The air rushes out and pushes the air outside away from the bag. The air continues to

move forward in a wave. When the moving air reaches your ear, you hear a sound.

Thunder is produced in a similar way. As lightning strikes, energy is given off that heat the air

through which it passes. This heated air quickly expands producing energetic waves of air

resulting in a sound called thunder.

MAKE A THUNDERSTORM

Materials:

clear, plastic container (size of shoebox)

red food coloring

ice cubes made with blue food coloring

Process:

Fill the plastic container two-thirds full with lukewarm water

Let the water sit for one minute.

Place a blue ice cube at one end of the plastic container.

Add three drops of red food coloring to the water at the other end of the plastic

container.

Watch what happens.

Explanation:

The blue and cold water sinks while the red and warm water rises. This happens because of

convection. The blue water represents the cold air mass and the red water represents the

warm, unstable air mass. A thunderstorm is caused by unstable air and convection plays an

important part. A body of warm air is forced to rise by an approaching cold front therefore

thunderstorm’s form.

LIGHTNING

Lightning is a bright flash of electricity produced by a

thunderstorm.

What causes lightning?

Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice

(frozen raindrops) bump into each other as they move around in the air. All of those collisions

create an electric charge. After a while, the whole cloud fills up with electrical charges. The

positive charges or protons form at the top of the cloud and the negative charges or electrons

form at the bottom of the cloud. Since opposites attract, that causes a positive charge to build

up on the ground beneath the cloud. The ground’s electrical charge concentrates around

anything that sticks up, such as mountains, people, or single trees. The charge coming up from

these points eventually connects with a charge reaching down from the clouds and - zap -

lightning strikes!

Have you ever rubbed your feet across carpet and then touched a metal door handle? If so,

then you know that you can get shocked! Lightning works in the same way.

MAKE LIGHTNING IN YOUR MOUTH

Materials:

Peppermint lifesavers

dark room

mirror

Process:

Go to a really dark room and stand in front of the mirror. Wait a few minutes until

your eyes get accustomed to the darkness.

Put a Peppermint lifesaver in your mouth.

While keeping your mouth open, break the lifesaver up with your teeth and look for

sparks. If you do it right, you should see bluish flashes of light.

Explanation: Why does this happen? When you break the lifesaver apart, you’re breaking apart sugars inside

the lolly. The sugars release little electrical charges in the air. These charges attract the

oppositely charged nitrogen in the air. When the two meet, they react in a tiny spark that you

can see.

RAIN AND FLOODS

How does rain form?

Water droplets form from warm air. As the warm air rises in the sky it cools.

Water vapor (invisible water in the air) always exists in our air. Warm air

holds quite a bit of water. For example, in the summer it is usually very

humid. When enough of these droplets collect together, we see them as

clouds. If the clouds are big enough and have enough water droplets, the

droplets bang together and form even bigger drops. When the drops get

heavy, they fall because of gravity, and you see and feel rain.

What causes rain?

When clouds develop or rain occurs, something is making the air rise. Several things can

make this happen. Mountains, low-pressure areas, cold fronts, and even the jet stream.

How big are raindrops?

Raindrops are much smaller than we think!

They are actually smaller than a centimeter. Raindrops range from 0.0254 centimeter to 0.635

centimeter in diameter.

How fast do raindrops fall?

Not including wind-driven rain, raindrops fall between 11 and 29 kilometres per hour in still air.

The range in speed depends on the the size of the raindrop. Air friction breaks up raindrops

when they exceed 29 kilometres per hour.

What is a flood?

A flood results from days of heavy rain and/or melting snows, when rivers rise and go over

their banks.

What is a flash flood?

A flash flood is sudden flooding that occurs when floodwaters rise rapidly with no warning

within several hours of an intense rain. They often occur after intense rainfall from slow

moving thunderstorms. In narrow canyons and valleys, floodwaters flow faster than on flatter

ground and can be quite destructive.

MAKE A RAIN GAGUE

Materials:

clear jar

ruler

Process:

Put a jar outside in an open area before it starts raining.

After it stops raining, measure how many inches of rain are in the jar with your ruler.

You can also use a jar to see how much water is in snow. Put an inch of snow in a jar,

then bring it inside and let it melt. Heavy wet snow will have a lot more water in it than

dry fluffy snow.

Explanation:

You’ve just created your own rain gauge and can measure how much you received from the

storm!

SUCK AN EGG INTO A BOTTLE

What does an egg in a bottle have to do with the weather??? Pressure! Weather forecasters

measure air pressure with a barometer. Barometers are used to measure the current air

pressure at a particular location.

Materials:

glass bottle with a long, narrow neck (an apple cider jug works well)

boiled egg

matches

Process:

Put the empty bottle on a table.

Peel the boiled egg.

Light a match and drop it into the bottle. Repeat about three or four times.

Quickly put the egg over the mouth of the bottle.

Explanation:

What happens? The lit match heats the air inside the bottle. When air is heated it expands and

takes up more room. As the heated air expands, some of it escapes out of the bottle. When

the matches go out, the air inside the bottle cools and contracts, which takes up less room.

This creates a lower pressure inside the bottle than outside the bottle. The greater pressure

outside the bottle forces the egg to get sucked into the bottle.

To get the egg back out of the bottle, tilt the bottle and blow air into it. Make sure you get out

of the way, because the egg will shoot out!

Explore how differing pressure systems affect the weather.

MAKE IT RAIN

Materials:

glass mayonnaise or canning jar

plate

hot water

ice cubes

index cards

Process:

Pour about 5cms of very hot water into the glass jar.

Cover the jar with the plate and wait a few minutes before you start the next step.

Put the ice cubes on the plate.

Explanation:

What happens? The cold plate causes the moisture in the warm air, which is inside the jar to condense and form water droplets. This is the same thing that happens in the atmosphere.

Warm, moist air rises and meets colder air high in the atmosphere. The water vapor

condenses and forms precipitation that falls to the ground.
