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 work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!
