Sense of Your Investigation
- What could
you conclude? Does color make a difference in the amount of the sun's
energy that something absorbs?
- If so,
which colors seem to store more heat energy?
- How would
you use your findings to help explain how the monarch's wings and thorax
are adapted to survive in cool temperatures?
