| What
does water vapor look like? Where does rain come from?
What
you need:
Two pitchers or glasses, ice, water
| What
to do: |
| 1. |
Fill
one pitcher or glass with water and ice, the other with
only water. |
| 2. |
Have
the students look at the pitchers/glasses immediately
after they are filled and note what is on the outside
surface. Write down their description. |
| 3. |
After
15 minutes, have them look again at the surfaces.
What has changed? Where did the water on the surface
of the ice-filled container come from?
If they say it leaked from inside the pitcher, point
to the ice-less container. Shouldn't it also show leakage?
|
| 4. |
Talk
about hot water coming from a faucet or shower making
water vapor, or how your breath makes a cloud on a very
cold day. |
