Basic Cloud Formation

Materials

Large clear plastic soda bottle with screw-on cap

Squeeze bottle with long plastic hose

5 different color pens

Dark-colored construction paper

Wooden matches

Safety glasses

Create a Cloud in a Bottle

No water What change did you

Air pressure influences the formation of clouds in the atmosphere.

Valve stem

Drill

3/8-inch drill bit

2-liter clear plastic bottle with cap or stopper

Foot pump

Safety goggles

Let’s Pause for Questions.

Tips and WarningsThe use of safety goggles is strongly recommended.

Over pressurization of the bottle may cause it to rupture or explode.

Another version of Cloud in a Bottle, using rubbing alcohol and NO matches.

Further Investigation

What effect does water temperature have on the cloud formation?

Does the size and type of particle make a difference in cloud formation? (smoke from a candle, chalk dust, talcum powder, etc.)

Using a slide projector or strong flashlight, shine some bright light through the bottle and view the bottle from various angles. The scattering and diffraction may cause different colors to emerge, and these colors can change.

Question: True or False

Contrails are CLOUDS

√ True

X False

1. Determine the satellite’s overpass time

2. Observe and record the cloud properties at your location:

cloud type and level cloud cover visual opacity

3. Upload your results to NASA

4. Compare results with satellite-retrieved properties
