This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

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 use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

Learners investigate how the temperature of water affects its density.
