After watching a video demonstration and copying plans into their notebooks, Mr. Michler’s STEM Science students brainstormed the best ways to use plastic cups and paper clips to create cradles for wire axles that could spin easily when connected to direct current.
This related video shows a similar process using other simple materials:
Mr. Michler traveled between tables to answer questions and demonstrate strategies for the best results. He explained that his students are studying energy transformations. This lab shows how stored chemical reactions can be transformed into electrical energy and then into kinetic energy.
I overheard one student admonish his table-mates: “No! Don’t do anything yet. We need cooperation before we decide what to do first.”
