Two photos show middle school students working together in a science classroom during a hands-on lab. Students gather around lab tables measuring, pouring, and observing materials in containers filled with small rocks or gravel, modeling an aquifer while using textbooks and data sheets to guide their work.

Science students study how to sustain fresh water as a renewable resource. 7th graders observed how the rate of use and the rate of replenishing water affect our aquifers.
