pH of Soil—Super Value Laboratory Kit
Students determine the pH values of local soil, the causes of different pH levels and more with this easy-to-follow procedure. Students use a pH indicator solution, collected soil samples and sampling cups to accurately measure the pH of their soil samples. Includes detailed instructions and background information. Super Value Kit is complete for 5 classes of 30 students working in pairs for more than 500 tests!

Groundwater Simulation Model— Guided-Inquiry Kit
In this guided-inquiry activity, students inves- tigate groundwater-related concepts before designing and building their own simulated groundwater models. Construct and explore aquifers, restrictive barriers, pollution sources, aerated zones and saturated zones. Complete with detailed background section, teacher notes and tips and enough materials for 30 students working in pairs.

Soil pH Meter
A simple, easy-to-use meter for measuring the pH of soil quickly determines whether soil is suitable for particular plants or if the pH needs to be adjusted. Included foldout guide offers soil pH preferences of more than 400 plants, detailed instructions for accurate measurements and techniques and materi- als for adjusting soil pH. Includes meter, 4" probe and probe cable. Requires no batter- ies or external power.

Water Cycle Adventure— Super Value Kit
This interactive exercise helps students understand the complexity of the seemingly simple water cycle of evaporation, conden- sation and precipitation. Rolling a specially designed die at each “water cycle station” determines next steps and increases student awareness about hydrologic processes. After traveling through the water cycle, students compare experiences. Super Value Kit is complete for 30 students working individu- ally. All materials are reusable.

Groundwater Exploration Activity Model
This durable acrylic model teaches students about groundwater sources, its storage
and flow beneath Earth’s surface and how it impacts life on Earth. Dyes represent contam- inants to show pollution and how it directly affects the environment. Includes everything for the simulation of groundwater principles as well as an electric pump for continuous water recharging and a large reservoir. Sturdy design includes 7” base for added stability. Size: 20" L × 5" W × 121⁄2" H.
