This is the amount of matter in something.
What is mass?
This is the energy a moving object has.
What is kinetic energy?
Which state of matter has a volume and a shape that stay the same?
What is a solid?
This is a change the does not change the type of matter it is.
What is a physical change?
This is another word for burning.
What is combustion?
This is anything that takes up space.
What is matter?
This is the energy of position, or the energy of condition.
What is potential energy?
Which state of matter has no definite shape or volume?
What is a gas?
This type of change creates a new kind of matter.
What is a chemical change?
Most of the world's energy comes from here.
What is the sun?
This is how much space something takes up.
What is its volume?
Plants need this type of energy to grow.
What is solar energy?
Which state of matter has a volume that stays the same, but a shape that changes?
What is a liquid?
These are things found in nature that living things use.

Balance?
If two boxes are the same volume but different masses, which one will have the higher density?
The box with more mass is denser, and the one with less mass is less dense.
This is how you can change potential energy to kinetic energy.
Let something fall from a high place, or stretch something and let it go.
List 5 ways to save energy resources
Turn off lights when you are out of the room
Don't use A/C or set it to 27
Take public transportation like buses and trains instead of cars
