  1. 1. Chapter 7 Lesson 4 How do clouds form?
  2. 2. Make a cloud demonstration <ul><li>Demonstrate cloud formation with a large, wide-mouthed jar, a match, a cup of very warm water, a rubber band, and a plastic bag. </li></ul><ul><li>Pour the water into the jar. </li></ul><ul><li>Drop a lit match into the jar, then quickly cover it with the plastic bag. </li></ul><ul><li>Secure the bag on the lid with a rubber band. </li></ul><ul><li>Push the bag into the jar, and pull it out again. A cloud will form. </li></ul><ul><li>Ask: How did the match help form a cloud? Why do you need to secure the plastic bag onto the jar? </li></ul>
  3. 3. Clouds are made of: <ul><li>water vapor or ice crystals - depends on temp. & air pressure </li></ul>
  4. 4. Activity- How many drops of water can a cloud hold? I predict that the cotton ball will hold _____ drops of water before it overflows. Result: The cotton ball held ___ drops before it overflowed.

  6. 6. Types of clouds Cloud Where it forms Description cirrus > 6,000m above ground High altitude, thin, wispy & white cumulonimbus thunderhead Base-1,000m above ground Top-12,000m above ground Vertical cause thunderstorms cumulus Base-2,000 -7,000 m above ground Mid-altitude, puffy stratus <2,000m above ground Low altitude Dark, cover sky fog Ground level Forms b/c air cools
