EARTH SYSTEMS: SOIL & SOIL DYNAMICS, continued
Worm Farm
All the materials for maintaining healthy worms are included: an insulated eight-quart container with built-in ventilation plugs,
11⁄2 pounds of worm bedding and 4 ounces of worm food. Bedding will support 100 nightcrawlers per pound or roughly twice
as many smaller worms. Worms can be
kept for several months. Includes complete instructions.
AB1414 I Complete Farm I $19.75
AB1415 I Worm Bedding I $4.15/1.5 lb pkg.
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, decompo- sition, 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. FB2209 I Compost Kit I $92.95

Introduce students to how soil is formed,
the bridge between the living and non-living worlds. 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 working in pairs.

Chemical and Mechanical Weathering of Rock—
Student Laboratory Kit
In this wide-ranging student lab kit, students will experiment and observe how mechani- cal weathering, geological changes, glacial changes, ice expansion, chemical weathering, 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 on rocks.

Be a Mineral Detective—
Copper Mining—
Student Laboratory Kit
Student Laboratory Kit
Students must identify eight mineral unknowns by name by gathering evidence through tests of observation, light interac- tion, streak, mineral hardness, cleavage, smell, ice and solubility. Includes student laboratory sheets, teacher notes, 15 sets of mineral testing chips, a large teacher display set, 15 poster-size data tables and all special- ized materials. Complete for 30 students working in pairs.
AP5949 I $86.45
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.
