Environmental Literacy and Inquiry Working Group, Lehigh University

In this activity, which comes at the beginning of a 40-day sequence of activities in an energy module, students observe the transfer of solar energy to different appliances with a solar cell and investigate the effect of using different solar sources to supply energy to appliances.

1 or 2 90-minute lab periods, depending on students' familiarity with building circuits. Solar Energy Kits: Wires/ photovoltaic cells/ light bulbs/ music box/ fan / etc.

Teaching Tips

  • Students should have previous experience wiring circuits and be familiar with the differences between series and parallel circuits before completing this activity.
  • Could be used in technical schools that focus on engineering or could be used informal education.

About the Science

About the Pedagogy

  • Students investigate solar energy with a combination of watching video clips and building their own photovoltaic cell to power several small appliances.
  • Assessment requires a log in, so is protected against students going online to look up answers.
  • Does not offer a lot of inquiry, as it is 'cookbook style.'

Technical Details/Ease of Use

  • Photovoltaic Cells video clip seemed to end early as if the entire clip wasn't loaded all the way.
  • Pictures of wiring in instructor and student handouts may help students who have not had much experience with creating different types of circuits.
  • Lab kits must be purchased (wires/ photovoltaic cells/ light bulbs/ music box/ fan / etc.), which may be a major limitation for some schools.
