Problem
I. Water can move among three phases - solid, liquid, and gas.
i. How does the movement of water molecules change when water goes from solid ice to liquid?
ii. How does the movement of water molecules change when water goes from liquid to gas?
II. What two characteristics of Earth allow liquid water to exist?
III. Draw a diagram of the water cycle. Be sure to label the following steps: precipitation, condensation, evaporation, transpiration, and surface runoff.
IV. What steps of the water cycle cause rainy weather conditions? Use the terms evaporation, condensation, saturation, and precipitation in your explanation.
V. Recreate the water cycle in the comfort of your own home: Fill a glass with warm water. Fill a second glass with cold water, and add a few ice cubes.
i. What does the outside of the glass with ice cubes feel like?
ii. What caused this change?
iii. Why didn't the same thing happen to the glass filled with warm water?
