EARTH SYSTEMS: SOIL & SOIL DYNAMICS, continued
Exploring the World of Soil
Sedimentator
This unique tube is used to demonstrate the process of sediment 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.
AP5121 I $17.35
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 will gain valuable insight on protozoans—the “lions and tigers” of the soil—as they explore soil samples and quan- tify the number of these organisms. Comes complete for 30 students working in pairs. FB1785 I $55.05
Soil Ecology Lab Manual
Through 18 labs, students learn how envi- ronmental factors like the nitrogen cycle, pH, plants, precipitation and UV radiation affect soil as well as how to perform serial dilutions, extract protozoa and count bacteria and yeast colonies. Students discover how the ecology of soil influences multicellular organ- isms on Earth.

Investigating Plate Tectonics
Volcanic activity, earthquakes, flooding— relate dynamic forces such as these to the origin of continents, ocean basins, mountain ranges, and the processes of plate tecton- ics and sea floor spreading! This detailed chart features actual specimens of rocks and minerals securely mounted on the chart, allowing students to see and trace the action of the rock cycle.
AP5199 I $65.45
Modeling Faults—Student Activity Kit
In this hands-on activity kit, students create multicolored and multilayered landform models that simulate normal, reverse and strike-slip faults to explore the properties of types of faults. A unique and inexpensive way for students to investigate the movements of each type of fault. Includes detailed procedures, student handouts and Teacher Notes. Complete for 30 students working in pairs.
