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 data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
