Purpose: The Earth-Water Absorption and Radiation Laboratory was established to
evaluate how different Earth surface materials absorb heat and to show how the angle
of sunlight affects the planet and surface temperature. It took about an hour to complete
the lab. The main topic of the laboratory was "What affects the absorption of sunlight on
the ground and surface?"
Procedure: 1: Evaluate the materials and absorption rates. 2. Open the lab 3. Notice
how the radiation angle affects heat 4. Soil Absorption 5. Continue to the next part of the
lab. 6. Get Sea breeze and wind direction information.

Conclusion: All in all, my theory was correct. The air warmed more than I expected,
although some materials did not warm as much as I thought. It was also interesting how
different factors can change the smoke and its direction.
