draw example

400

Describe what happens to the motion of molecules as water changes state.

particles increase their motion as they become a gas, they decrease as they become a liquid and then a solid

400

What is a mixture?

different types of molecules not bonded together

400

How do we get synthetic resources?

from natural resources that are chemically modified

400

Draw what particles look like in a solid, liquid and a gas

solid-close together

liquid-medium distance 

gas-far apart

400

How might you know that a chemical change took place?

the substance is different

the substance has been burned

the particles have been changed

gas bubbles occur

500

A water bottle was left in your car on a cold day. When you return to the car, you notice that the bottle has changed shapes. Why did that happen?

The air particles in the bottle moved closer together because they were cold. This made the sides of the bottle go in.
