1. LIVE INTERACTIVE LEARNING @ YOUR DESKTOP December 1, 2011 NES: Meteorology: How Clouds Form Presented by: Rudo Kashiri

2. Meteorology: How Clouds Form Rudo Kashiri NES Education Specialist NASA Langley Research Center

3. Agenda  Featured lesson: How clouds form  NASA Connection  S’COOL Project: Extension Activity  NASA Explorer Schools

4. 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

5. Chapter 12: How Clouds Form - Understanding Principles of Precipitation Where to find the lesson http://www.nasa.gov/audience/foreducators/topnav/m aterials/listbytype/Meteorology_Guide.html

6. Poll question A. Cirrus B. Cumulus C. Stratus D. Nimbus What type of cloud is illustrated below?

7. Cumulus – lumpy Cirrus – wispy Stratus – layered Nimbus – raining Alto – mid-level Contrails - streaks Name the combinations (Write answer in the chat)

8. Let’s Pause for Questions.

9. How do clouds form? A. Evaporation B. Condensation C. Rain D. Radiation

10. 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

12. 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?

14. Let’s Pause for Questions.

15. 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

16. Tips and warnings  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/ex periment/cloud-in-a-bottle-experiment

17. 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.

19. Why does NASA study clouds? (Type your responses in the chat)

20. The name of this science experiment is CERES NASA has a science project

22. S’COOL CERES Project

23. Students Observed Satellite View of Clouds What else did the students report seeing? Mountains with snow & ice

24. Welcome to S’COOL  Real-world science experiment  Cloud science and satellite data in the classroom  CERES contribution to our understanding of climate  Weather instruments  Inquiry-based learning  Resource materials for teachers  Global Cloud Observation Day, January 13
