In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

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.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

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.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
