In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this activity, learners will pretend to be archaeologist using this chilling experience.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

Historically, sea floor mapping (bathymetry) was done by soundings.

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

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).

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