Presented by: Rudo Kashiri
Agenda
Featured lesson: How clouds form
NASA Connection
S’COOL Project: Extension Activity
NASA Explorer Schools
How Clouds Form
Grade level: 5 - 9
Subject Area: Earth Science
National Science Standards: Structure of Earth system Transfer of energy
Structured inquiry activity Objective:
Introduce the basics of cloud formation
Chapter 12: How Clouds Form - Understanding Principles of Precipitation

Alto – mid-level
Contrails - streaks
Name the Combinations(Write answer in the chat)
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
observe inside the bottle?
Just water What change did you
observe inside the bottle?
Water and smoke What change did you
observe inside the bottle?
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
Matches
Water
Foot pump
Safety goggles
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.

Now Guess the Cloud Cover
Be ready with an answer in 5 seconds!
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
