Students should add different amount of water to each square. The important thing here is that the same textured soil samples will have different water contents. Place the soil samples in the same area so that they are exposed to the same amount of direct sunlight or a heat lamp. Record temperature at each depth at five-minute intervals. Or, to encourage inquiry science, require students to construct their own ways to record, keep track of, and display their data.
Students summarize the results from their lab in one concise paragraph.
Use data to support your answer. State the dependent variable. Students must identify soil saturation based on graph. Students design an experiment demonstrating texture of soil and its effect on soil temperature. Please send an e-mail to Patti Harrison .
