Activity 2

For this activity we only had to read about 1.5 pages about dew and its affects on clouds. I learned that if the percentage of dew is above 65% then it attacts the clouds because the wind blows the clouds that way. The higher the amount of dew the more it rains in that area. There is more dew in areas that are close to a body of water, like a river, lake, or ocean.

Activity 1

In class today, we had three bowls and each one contained a different item. One had dirt, another had water, and the last had snow. The point of this activity was to see how different conditions affected each of the items. After putting a thermometer-like instrument into the bowls we shone a lamp on each of the bowls to see how the temperature changed after 10 minutes. The snow's temperture did not change but the temperature of the water and dirt rose. The water's temperature rose much quicker than the dirt's temperature. Then we let the bowls cool off for 10 minutes. The water's temperature fell quickly, the dirt's temperature fell much slower, and the snow's temperature did not change. From this activity it shows that snow does not absorb heat but it does reflect light.
