When You're Hot, You're Hot
WHY? question_guy
The surface temperature will vary throughout the day at each of the reading sites due to different factors. Radiant energy is the strongest when thermometers are placed directly in the sun and on a surface that absorbs radiant energy. Thermometers in the shade do not receive the radiant energy and the energy is not absorbed as great as in the direct sun on an absorbent surface. Two thermometers in the sun but on different absorbent surfaces will have different readings.
ASSESSMENT: Can the student communicate what they observed?
