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.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.
