WHY?
|
|
- 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?
|
 |
|
|
Student is able to communicate that the warmest sites with
dark surfaces receive the most sunlight and the coolest locations
with light surfaces receive less sunlight. Radiant energy is
absorbed into darker surfaces.
|
|
Student is able to communicate that the dark surfaces become
hotter and the lighter areas are not as hot. The sun produces heat
energy.
|
|
Student is able to communicate that asphalt get hotter that the
grassy area.
|
|
Student is able to communicate that it is hot in the sun and
cool in the shade.
