In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this activity, learners will experiment to find how long it takes to compost paper. They will create their own compost container and test different variables.

In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.

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 plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

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 activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.

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

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.
