States of Matter
What are the three states of matter?
Solid, Liquid, Gas.
What happens to water when it freezes?
It turns into a solid (ice).
What is an example of matter that is a gas?
Air, oxygen, carbon dioxide.
What do we call the process of turning water into steam (liquid to gas)?
Evaporation.
What is an example of a liquid?
Water, juice, milk.
If you heat up a liquid, what does it turn into?
It turns into a gas (like steam from boiling water).
What is an example of a solid that can be found in the classroom?
A pencil, book, desk.
What is an example of a change in matter that happens when you cook macaroni and cheese?
- Evaporation when boiling the macaroni.
- Melting of the cheese.
Which state of matter has a definite (constant/unchanging) shape and volume?
Solid.
________ is a change from gas to liquid.
Condensation.
What is a common example of a liquid in the classroom?
Water, juice, coffee, tea.
If you leave a chocolate bar outside in the sun, what change happens to it?

In which state of matter are particles spaced out the most from each other?
Gas.
What do we call it when a solid changes to a liquid?
Melting.
Can you see gas? Why or why not?
No, gas is invisible because its particles are spread out and move quickly.
When you add heat to a piece of ice, what type of change happens?
The ice melts (physical change).
What happens to the particles of a solid when it turns into a liquid?
The particles begin to move more freely and spread apart.
What happens to water when it evaporates?
It turns from a liquid into a gas.
What happens to the matter in a piece of ice when it melts on a warm day?
The solid ice turns into a liquid water.
Name the three stages of the water cycle.
Evaporation ---> Condensation ---> Precipitation
You are holding a ball in your hand.
What state of matter is the ball?
What state is the air inside the ball?
