The 3 phases of matter.
What is solid, liquid, and gas?
100
This is a change in chemical composition.
What is a chemical change?
100

A measure of how much matter is contained in a substance.

What is mass?

100

distance/time = ?

Speed

200
The neutrally charge part of an atom.
What is a neutron?
200

A substance in this phase will always have the same shape and volume.

What is a solid?

200
This is a change that does not result in the formation of a new substance.
What is a physical change?
200

A measure of how much space an object occupies.

What is a volume?

200

Change in speed/change in time =

acceleration

300
The positively charged part of an atom.
What is a proton?
300

A substance in this phase will have variable volume.

What is a gas?

300
Rust is an example of this kind of change.
What is a chemical change?
300

A measure of how much mass is contained per unit of volume.

What is density?

300

This value must always be grater than or equal to distance.

What is displacement

400
The only subatomic particle located outside of the nucleus.
What is an electron?
400
A substance in this phase takes the shape of it's container, but always takes up the same amount of space.
What is a liquid?
400

Ice melting into liquid water is an example of this

What is physical change

400

Aspect of an experiment that the researcher defines and implements. 

What is the independent variable?

400

What is the average speed of a bicyclist who traveled 20km in 2hours? (50 extra points if you can answer in m/s round to nearest 10th)

10km/h. (2.8m/s)

500
If we say that atoms typically have a neutral charge, the number protons _____ the number of electrons.
What is equal to?
500

Gas fills a container to a specific __________ based on its mass and the volume of the container. This can also force a substance to change state (it is NOT heat).  

What is pressure?

500
This is the kind of change a phase change is considered to be.
What is a physical change?
500

The field of science concerned with the motion of objects.

What is a kinematics?

500

If a car was going 25m/s and needed to slow down to 15m/s in 5 seconds to avoid a crash what was its acceleration.

-2m/s
