  2. Water In the Air • When the water cycle is discussed students can connect that water evaporates into the air. • Increasing the forward fraction shows that more water goes into the air on a hot day. • The air can become saturated at a certain temperature. • Then if the air is cooled, the forward fraction decreases and … • … WATER comes out of the air as … RAIN.

  3. Increase and Decrease Fraction Increase and decrease the fraction and see what happens (evaporation and then rain).

  4. Make a Cloud in a Bottle • To further explore the connections to weather, we have links from the Home Page to show how to make a cloud in a bottle. • Again this is saturation related which means it has to do with forward and backward processes (where now the fraction is changed by pressure, not by heat).
