Oct, 2017 - As Heritage’s 7th graders explored, not only the hydrologic cycle, but also humans’ effect on it.
Students measured 100 milligrams of gravel, prior to determining how much water it would absorb. In addition to testing gravel, Raeschelle McDonall worked with team members to calculate soil’s porosity. In this picture, Heaven Goodman, Forrest Smart, and Damir Bass are practicing the science skill of accurately reading graduated cylinders. Heaven Goodman prepares for the Porosity Lab by measuring liquids into a graduated cylinder. Latayviah Greer helps others determine the porosity of soil, so the class can determine which soil would be best for an aquifer, which would be best for farming, and which would allow contaminants to cycle through earth’s waters. By using the STEM Lab’s Moisture detector, Latayviah Greer is able to determine the porosity of soil. After completing the lab, Amaya Dennis created graphs to communicate her data before synthesizing results. To achieve mastery, Maya Jordan and Dezzarae Kyles collaborated as they analyzed their results.
