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

In this laboratory activity, learners use a simple procedure to bait oomycetes from water and/ or soil and then examine these fungus-like organisms with the microscope to see how they look.

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

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.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

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.
