Over the last few weeks, the 1st and 4th graders have worked together on a STEM (science, technology, engineering, and math) project. They were given the task of building an object that could float, but first learned some key terms, including gravity, surface area, density, and buoyancy. Equipped with these facts, they paired up and started designing their floating device. Each team included a 4th grader and a 1st grader.
Last Thursday, they put their plans into action! Using donations of recyclable items from home, the teams implemented their designs. Once they were satisfied with the product, they put it to the test. If the object could float, they added small critters to see how much weight it could bear. If it didn't float, they returned to their station, made adjustments, and tried it again.
