Hold a Hill
Source Institutions
In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.
Coastal Erosion: Where's the Beach?
Source Institutions
Learners use beach profile data from a local beach or online data from Ocean City, Maryland to investigate coastal erosion and sediment transport.

Vanishing Craters
Source Institutions
In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

The Ability of Permeability
Source Institutions
In this activity (page 11 of the PDF), learners investigate how quickly water moves through various materials. They measure and compare the permeability of gravel, sand, and soil.

Exploring Earth: Land Cover
Source Institutions
This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

Seas in Motion
Source Institutions
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.

The Carbon Cycle: How It Works
Source Institutions
In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

How Boulders Are Born
Source Institutions
In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

Dinosaur Breath
Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Regolith Formation
Source Institutions
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.

Stream Table
Source Institutions
In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

Earth and Mars
Source Institutions
Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land

Ice on Mars
Source Institutions
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.

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

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

Trail Impact Study
Source Institutions
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.

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

Weathering and Erosion
Source Institutions
In this activity (page 13 of the PDF), learners discover how weathering and erosion change the Earth’s surface.

The Crayon Rock Cycle
Source Institutions
In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

Beach Buckets
Source Institutions
In this activity, learners explore a bucket of sand and beach objects.
