Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this activity, learners examine the culture and history of the tomb site.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

Learners investigate how the temperature of water affects its density.
