what is an independent variable

• the variable that doesn't change

• the variable that does change

What does mass measure?

• the milliliters in a beaker

• the centimeters on a meter stick

• how much matter there is

• how much space matter takes up

in a solid if temperature increases what happens to particles?

• there is no change

• Particles slow down

• particles speed up

• particles start to move
