In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this chemistry demonstration, acid rain is simulated in a petri dish.

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 edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

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 (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.
