Solids, Gases and Air
It is anything that takes up space and has weight, like you, me, and the desk you are sitting at!
Matter
This is the special temperature when solid ice warms up and turns into liquid water.
Melting point
A giant, slow-moving river of ice found high up in the mountains, like the ones you can visit in Jasper and Banff!
Glacier
Tearing a piece of paper, cutting your hair, or melting an ice cube are all examples of this type of change, because you aren't making anything brand new.
Physical Change
This state of matter keeps its own shape. A rock, a pencil, and an ice cube are examples of this.
Solid
This is the temperature when liquid water gets so cold it turns into solid ice.
Freezing Point
This tricky weather falls from the sky as a liquid, but turns into slippery ice the second it hits the cold ground.
Freezing Rain
Baking a cake or burning campfire wood is this type of change, because you make something completely new that you can't turn back!
Chemical Change
This state of matter does not have its own shape, but it expands to fill up the whole container it is in, just like inside a balloon.
Gas
This is the temperature when liquid water gets super hot and bubbles turn into steam (a gas).
Boiling Point
Glaciers are made when thousands of years of this fluffy white stuff gets squished down really hard.
Snow
Mixing baking soda and vinegar together makes fizzy gas bubbles. Because gas is created, it is a clue that this type of change happened.
Chemical Change
Even though it is invisible, it is a gas that is all around us, and we breathe it in every day to live!
Air
If you check a thermometer in Alberta during the winter, water turns to ice at exactly this many degrees Celsius.
Zero Degrees
Freezing rain can make these outdoor paths very dangerous for recess, so teachers might tell you to walk like a penguin!
Sidewalks, roads or playgrounds.
This cool science idea tells us that everything in the universe is made of tiny, invisible building blocks that are always wiggling and moving.
Particle Theory
Air is actually made up of a mixture of these, including oxygen and nitrogen.
Gases
If you are cooking pasta, the water on the stove reaches its boiling point at this many degrees Celsius.
100 Degrees
When a glacier slowly moves over a mountain, it scrapes and breaks the rocks. Because it is just changing the rock's shape and size, it is this type of change.
Physical Change
According to Particle Theory, the tiny particles in this state of matter are packed super tightly together and just vibrate in place.
