Students will enjoy putting their learning to work in this engaging lab. Using springs or rubber bands, students measure and record data as they try to get a bucket to touch the floor by adding weights. Then they use their data and its graph to make predictions and write equations that will help them predict the outcomes. This simple and inexpensive lab will help your students learn graphing, t-tables, measurement, linear functions, and the physics of tension forces. This can be used as a stand-alone STEM activity or integrated into a unit on physics and functions.
