Draw out how particles look in all three states of matter (for double points: act out as a group)
Solid: group should stand close together. Liquid: linked arms, but able to move. Gas: should be moving around bouncing around, not connected

TRIPLE POINTS! What is the difference between the particles in a liquid, gas, and solid? (hint, think back the video and the doors the particle visited)
Solid: they are tightly compacted and do not move. Liquid: they are still connected, but not as compacted and move as a team. Gas: the particles are separate and move freely.

Double points!!! In what way can we physically change a piece of paper? In what way can we chemically change a piece of paper?
1. crumpling, tearing, cutting... 2. burning the paper

condensation is caused by a decrease of temperature, Evaporation is caused by an increase of temperature

Act out how particles look in all three states of matter as they change from a: 1. solid to a liquid 2. a liquid to a gas, 3. a gas to a liquid 4. a liquid to a solid.
1. should start out a solid group and then connect and move. 2. should separate and begin to move around freely 3. should begin to come back together to be connected, but still moving 4. should stand still as one solid group.
