Bell activity: What is temperature?
How does your body sense temperature?
Feel it through your skin
How accurate is this? -- cold, warm, and hot water demonstration
Temperature - average kinetic energy of the particles in something
KE depends on mass and speed
Faster moving particles = higher temperature
Slower particles = lower temperature
Larger particles = higher temperature
Smaller particles = lower temperature
Thermal Energy - the TOTAL kinetic energy of the particles in something
depends on particle speeds
depends on number of particles
A boiling pot of water has a higher temperature than the ocean
The ocean has more thermal energy than the boiling pot of water because there are MANY more particles in the ocean
Oobleck Activity
Design a ship to travel to planet Oobleck, collect a sample, and return to Earth without getting stuck
Due Monday after break; we will present these in class
