Great control over temp, mass, number of particles.
2) Heater/Freezer Velocity graphs
Great display of how speed (velocity) of a particle changes as its temperature changes. Also, look at the averages temperatures!
The more collisions particle have, the harder they push on a surface. A balloon blows up because the air inside is having more colissions than the air outside!
4) Solar Ovens
Pressure vs. temperature.
Graphic, no text. Good visual for
nuclear chain reaction
n=restart
s=stop
chemical reaction over time. Concentration of 2 chemicals that change (and change color) over time. Not most intuitive but ok.
1001 things to do with Liquid Nitrogen (LN2)
Many of these I will NOT do! Some fun science ideas though.
Why marshmellows get big in a microwave!
