In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this activity (p.7-8 of PDF), learners examine fossil formation.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

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.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

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.

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

In this earth science activity, learners conduct a series of short experiments to explore how rocks change.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

In this activity, learners explore a bucket of sand and beach objects.
