• Ms. Mim's 6th grade science classes have been studying the two types of energy, Potential and Kinetic. This popsicle stick chain-reaction activity is a great way for the students to work with potential and kinetic energy. The reaction comes from potential (or stored) energy in the over/under weaving and kinetic (or motion) energy in the release. When the students have their chain ready they can feel the potential energy in the sticks and see the kinetic energy in their release.
