Objectives:
1. Students will become
exposed to the Digital Atlas of Idaho.
2. Students will understand why condensation occurs.
Materials:
| Pitcher of very cold water | Tray of ice cubes |
Procedure:
Use the climatology section
of the Digital Atlas of Idaho. To get there: Click on Atlas Home, Climatology,
then on Cloud Imaging.
This site of the digital atlas would serve as an excellent review before doing
this demonstration for the class. These pages will describe cloud formation,
condensation, evaporation, and relative humidity. These concepts are very important
for students to understand when talking about cloud formation.
Have
discussion on:
(see link above)
1. Cloud formation
2. Condensation
3. Evaporation
4. Relationship of relative humidity with temperature
Fill the pitcher with cold water and ice cubes. Place the pitcher of ice water in a warm room. Observe what happens on the outside of the pitcher.
Questions
for discussion:
1. Where does this water come from?
2. Would covering the pitcher prove that the droplets on the
outside did not come from within the container?
3. Why do cold water pipes drip in the summer?
4. Would the amount of moisture that accumulates depend upon
the amount of humidity on a particular day?
5. What happens when one blows hot air on a cold windowpane?
6. What do you think this condensation process has to do with
rain?
