Core Sampling
Simulate soil sample assemblages. Individuals create soil layers in a cup. They then use straws to collect core samples from these layers. What information can they glean from the core samples, I wonder?
DiscoverE
Solar-Heated Water
Heat up some interest in solar energy. Young engineers create a water heater that runs on solar power (simulated by a lamp). Using thermometers, they determine the change in temperature before and after the water goes through the heater.
