Exploring Groundwater— Activity-Stations Kit
Explore important concepts related to groundwater! Three “mini-lab” activities, each focusing on a specific groundwater-related principle or topic, are included: Permeability and Porosity, Groundwater Simulation Model and Permeable Reactive Barriers.

Porosity and Drainage Rate of Soil—Student Laboratory Kit
Do all types of soil hold the same amount of water? How much more water can one soil hold than another? Students perform three easy-to-follow lab activities to determine how pore size, soil texture, compaction and surface runoff are affected.

Soil Test Kit—Rapitest®
Quickly assess soil pH and the relative amount of three key elements—nitrogen, phosphorus and potassium (potash). Tests are as simple as dropping capsule contents into a sample and comparing the resulting color to a standard. The instructions detail how to conduct the tests, when to conduct the tests, preferred pH ranges for hundreds of plants and how to select and apply the proper fertilizers.

Exploring the World of Soil Protozoa—Student Laboratory Kit
The organisms that inhabit the soil are responsible for all of the ecological cycles that make life possible for plants and animals. In this kit, students gain valuable insight on protozoans—the “lions and tigers” of the soil—as they explore soil samples and quantify the number of these organisms. Comes complete for 30 students working in pairs.

This unique tube is used to demonstrate the process of sedi-
ment deposition in bodies of water and simulate rock formation. Students use this gadget to predict the order in which different sediments settle, observe and classify the types of sediments, iden- tify and explain how rocks are formed from sediments and observe how organic matter becomes trapped in sedimentary layers to form fossils.
