Meteorology: How Clouds Form Rudo Kashiri NES Education Specialist Langley Research Center
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
Where to find the lesson http://www.nasa.gov/audience/foreducators/topnav/ materials/listbytype/meteorology_guide.html Chapter 12: How Clouds Form - Understanding Principles of Precipitation
Poll Question What type of cloud is illustrated below? A. Cirrus B. Cumulus C. Stratus D. Nimbus

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 warnings To reverse the cloud formation, re-stopper and pump air into the bottle. The 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 http://www.stevespanglerscience.com/experiment/cloud-in-a-bottleexperiment
Further investigation What effect does water temperatures 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.
