List the three states of matter and provide examples for each.
Solid, Liquid and Gas
Examples will vary
What does expansion and contraction mean?
Expansion - to spread out, take up more space
Contraction - to close together, to take up less space

A ___________ contains particles that are arranged in an order and have structure.
Solid
Matter that cannot be separated by physical separation techniques.
Pure substance
Why might you see roads buckle after a very hot summer day?
The pavement will expand when it is hot causing the road to crack open.
List two things heat does to the particles.
1. Gives them energy
2. Makes them move faster
This city is the capital of Japan
Tokyo
A fixed shape
What do we call matter that can be separated by physical separation techniques. Give an example of this.
Mixture.
Examples: salad, smoothie, a cake, salt water
Using the idea of expansion and contraction, explain how an hot air balloon works.
As the air is heated inside the balloon, the air particles will expand and move at faster rates. The particles will have more spaces between them and become more spread out. This will allow the hot air to take up more space on the top of the balloon while colder air sink to the bottom.
What is the name of the energy that heat gives particles?
Kinetic energy
Newton is famous for this law of motion.
The law of gravity

4. Deposition
5. Condensation
6. Evapouration
List a device used to measure temperature. Describe how it works.
Thermometer - liquid in the glass will expand when the temperature increases and will move up the glass tube to show current temperature.
She wrote the famous Harry Potter books.

Describe the particles in a solid vs a liquid vs a gas.
Solid - compact, held tightly together, strong bonds
Liquid - particles flow over each other
Gas - particles are spread far apart
