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 (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

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

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

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.

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

In this multi-station lab, learners conduct a series of experiments to explore the processes and effects of weathering and erosion.

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

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

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

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 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.

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

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

In this activity, learners will learn how igneous rock, metamorphic rock, and sedimentary rock are formed as part of the rock cycle and that the same forces that produce/change rocks also produce/chan

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