In this chemistry demonstration, acid rain is simulated in a petri dish.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this activity, learners explore rocketry and the principals of space flight.

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

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
