Chemical and Mechanical Weathering of Rock— Student Laboratory Kit
In this wide-ranging lab kit, students experiment and observe how mechanical weathering, geological changes, glacial changes, ice expansion, chemical weather- ing, oxidation and organic processes affect rocks. Students observe which types of rocks are most affected by these processes and identify which chemicals and weathering processes have the greatest impact.

How Soil Is Formed—Student Laboratory Kit
Introduce students to how soil is formed, the bridge between the living and nonliv- ing world. Students will perform hands-on experiments to gain an understanding of the chemical, physical and organic processes involved in rock and soil formation. They
will investigate the results of erosion, glacial changes, ice expansion, chemical processes and more. Complete for 30 students work- ing in pairs.

Worm Composting Kit
Start an agricultural revolution with the equipment and instructions in this kit. Your students will team up with the redworm to discover concepts of recycling, decomposition, worm life cycles, soil ecology and organic farming. The cycle begins when they prepare the bin, introduce the worms and add the first food scraps. It is complete when they grow plants in the rich, organic soil.
Copper Mining—Student Laboratory Kit
Engage students in a real-world mining activity and build a complete environmental science lesson plan around it. In this unique lab, students extract and analyze copper from rock and mineral samples. In the process, they dig into the history, chemistry and environmental impact of metal mining in North America.
