We learned about clouds this week in weather. The kids learned that the three most important things needed to be present to form a cloud are moisture, cooling air and condensation nuclei. With the use of a rubber glove, matches, jar, water, lamp, and a rubber band, they were able to see water vapor form as the water heated under the lamp. When the jar was swirled, water molecules were able to be moved into the air.
Students took turns putting their hand inside the glove, which increased the air pressure. The air became more dense as the molecules crowded together. This also caused the air to heat up as molecules collided with each other more often.
