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

How clouds form  Grade level:  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 Where to find the lesson aterials/listbytype/Meteorology_Guide.html

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

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

Let’s Pause for Questions.

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

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?

Let’s Pause for Questions.

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  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 periment/cloud-in-a-bottle-experiment

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.

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

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

S’COOL CERES Project

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

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

Cloud cover

Now guess the cloud cover Be ready with an answer in 5 seconds!

Let’s Pause for Questions.

Question: True or False Contrails are CLOUDS A. True B. 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 S’COOL involves four steps
