Landon B. Gennetten, Lauren Cooper, Malinda Schaefer Zarske, Denise W. Carlson, TeachEngineering from Integrated Teaching and Learning Program

Student teams design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy. In this activity, students gain a better understanding of the three different types of heat transfer, each of which plays a role in the solar water heater design. Once the model devices are constructed, students perform efficiency calculations and compare designs.

Activity takes six to eight 45-minute class periods. Additional materials necessary.

Teaching Tips

  • Educator would ideally also draw connections to students' lives and personal energy use.
  • Educators may want to omit specific heat calculations particularly for non-physics students.
  • The metal storage tank would be more efficient if made of plastic; gluing to metal is more difficult.
  • The copper rods in Plan B need a more thorough explanation (Copper rods increase heating surface area).
  • Time needed for this activity might not be commensurate with the intended learning for this activity - educator might assign the construction as a term project.

About the Science

  • A really strong, well-organized activity, most suited for physics students (heat transfer concept and math level), but can be taught in other classes if supported adequately.
  • Good background information provided for educator.

About the Pedagogy

  • Offers both performance assessment (building and testing of solar heater) and good discussion questions.
  • Excellent illustrations help students through the building process.
  • Good activity for kinesthetic learners as it requires designing, building, and testing.

Technical Details/Ease of Use

  • Sophisticated design requires purchase of a fairly significant amount of copper tubing to construct the water heater.
