Como Afecta El Sol En Las Tierras

Hypothesis
• How does the sun affect temperature?
– It has no effect Or – The more exposure to the sun, the higher the temperature

Experiment Set Up
• Experiment Explanation • We placed three containers, one with black sand and two with gray sand and white sand. • Wemeasured the temperature of each every 5 minutes. We did it 5 times and wrote the results in this chart. • We also had a ‘control group’ with similar samples under a shadow.

The black sand did not present an increase in temperature under shadow, but increased its temperature under the sun. It was difficult to compare with the Gray Sand and white sand because theblack sand retained too much water, causing its temperature as the other sand.

The temperature of the Gray Sand increasesfaster than the temperature of the Light Sand, because they do not hold water.
