Keeping Damp in a Drought

In this maker challenge, students utilize the engineering design process as they design a way for mint plants to keep a constant moisture level for 72 hours. The mint plants must be kept moist since they are young and just starting to establish growth. Before students receive the mint plants, they must prove that they can keep the moisture level constant. Students employ the engineering design process and conduct research on different materials used to hold in moisture, evaluate proposed solutions, build and test prototypes, revise and improve their designs, and report their findings to the rest of the class.
