Grades 4-8: Battle of Bulbs

LED bulbs provide the most efficient source of light, far more efficient than incandescent or even fluorescent bulbs. However, incandescent bulbs are used most often in homes due to the higher initial cost of purchang LED or Fluorescent bulbs. In this activity, our middle school science club will use an "Energy Bike" to generate electricity and compare the three types of bulbs using their muscle power.
