Why Lesson Planet?
Seventh graders explore about energy transformations and trace them in a simple closed system. They build energy "chains" of their own design. Pupils complete a hands-on project where they attach the "links" in a "chain" connecting a battery (chemical energy), wires (electrical energy), and a small motor (mechanical energy), and then add additional "links" of their choices. Students complete a flowchart tracing the energy transformations in the finished project.
