        CAUTION: DO NOT AIM AT EYES

Materials: IR hand held infrared heat detector, stop watch, regular room thermometer, calculators and graph paper.
 Room Air temperature= _____ F/ Celsius. Outside Air temperature= _______ F/ C.       Ground temperature= ____ F/ C .

 

Objective(s): Students will use the IR hand held infrared heat detector to investigate various colored papers and objects.

 

Data sampling: Students will collect IR temperatures from the following car colors and perform an analysis of the results.

Record the results of both lab partners.      Analysis questions:

  1. Compare and contrast color results with your lab partner. How do they compare?
  2. How does your results compare to other lab groups?
  3. Rank the colors by temperature from highest to lowest?
  4. Can you postulate why there are differences in color temperatures?

   5. Predict the loss of heat rates for the colors?
Graph the results of the colors for two parameters of interest.
