Purpose: To provide an activity for a Science Fair Project investigating how the angle of the Sun's rays affects temperature change during the year.
Objective: Upon completion of the investigation, the student will be able to explain why the temperatures ranges are different at different latitudes and why they vary at the same latitudes during a year.
Materials: Light Source, Solar Panel, Motor and/or Voltmeter,
Procedure:
-
1. Place your light source at approximately a 15° angle to the solar panel and measure the energy produced.
-
2. Place your light source at approximately a 45° angle to the solar panel and measure the energy produced.
-
3. Place your light source at approximately a 90° angle to the solar panel and measure the energy produced.
Observation:
(table available in print form)
Conclusion: The light source perpendicular to the solar cell produces the most energy.
