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.

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

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 will model the mechanical weathering and erosion of rocks in a stream or river.

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

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 explore a bucket of sand and beach objects.

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
