Glass Hardness Plates
The perfect-size plate for mineral testing! Determine the hardness of minerals using these durable glass plates. If the mineral scratches the plate, it has a hardness factor greater than 5.5 on Moh’s hardness scale. Ideal 1" × 2" × 1⁄4" size for field or lab test- ing. Sold in packages of 10 plates.
Common Uses of Rocks and Minerals—Student Laboratory Kit
Many items we use every day are mined from the Earth, including limestone in building homes, feldspar in soaps and fluorite in toothpaste. Students will perform 10 hands-on activ- ities to determine the properties of various rocks and minerals and identify their common uses. An excellent introduction to the common uses and properties of rocks and minerals! Complete for 30 students working in pairs.

Rock Cycle Adventure— Super Value Kit
This random, interactive exercise shows the dynamic nature of the rock cycle, how rocks are formed and the forces driving the process. Rolls of a specially designed die at each “rock cycle station” determine next steps like weathering, melting or remain- ing in place. After traveling through the rock cycle, students compare experiences. Includes complete teacher notes, student worksheets and materials for 30 students working individually. All materials are reusable.
