PIRA Code(s): 4A30.20 Set up time:2 minutes Operation: Try putting the ring around the ball. At room temperature the ring is slightly larger than the ball. Heat the ball over a Bunsen burner and it will no longer fit through the ring. Physics and Science Concepts: Thermodynamics, Thermal Properties of Matter, Thermal Expansion Safety: Use caution when using a Bunsen burner. The Bunsen burner is not included in the experiment.
PIRA Code(s): 8A10.10 Set up time:none Operation: Plug in the model. Flip the right switch to have the planets move and the left switch to turn the light bulb on which represents the earth. Physics and Science Concepts: Planetary Astronomy, Solar System Safety: Do not touch the light bulb, it may get hot.
