After building the new vehicles by following the technical design, the students' got to test the amount of weight needed to put their vehicles in motion! We used bookend, string, two paperclips, our vehicles, and washers. Students started with one washer, and then they gradually added more. I walked around to gather predictions and observations. They recorded their findings in their science journals. After they recorded their findings, they were able to experiment with adding more weight. Some students' even thought about Newton's second law when they tried adding weight to their vehicle because that resulted them in needing more weight to move it!
