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 create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.
