Explain the concept learned when groups made up their own experiment with freezing.
Volume of when water is frozen. It stays the same from a liquid to a solid.

Why did the Kleenex not get wet when you put it in the top of a cup and then put the cup in water?
Gases got trapped in the cup as the cup was put into the water.

What materials did you have to use in the experiment showing that all solids have volume? (6 possible answers have to get 4)
Graduated cylinder, cork, nail, marble, water, pipette

Explain what the molecules in each state of matter look like and what they do.
Think back to the role play activity. Solids - form patterns and little vibrations Liquids - begin to flow, but are still connected Gases - go everywhere

Explain the concepts: Melting Point & Freezing Point Give 1 example.
They are the same thing for water. Other substances they may be different.

Explain the mass/volume for each: solid, liquid, and gas
Solid: definite shape & volume Liquid: volume & no definite shape - flows Gas: mass & volume & no definite shape
500
Explain the concept to be understood that dealt with the candle, jar, and water.
Oxygen is not the only gas in air. The candle burnt out because it needed oxygen to burn and all the oxygen was used up.
