Clouds are made of:

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.
Make a cloud demonstration• Demonstrate cloud formation with a large,
wide-mouthed jar, a match, a cup of water, a rubber band, and a plastic bag.
• Pour the water into the jar. • Drop a lit match into the jar, then quickly
cover it with the plastic bag. • Secure the bag on the lid with a rubber band. • Push the bag into the jar, and pull it out
again. A cloud will form. • Ask: How did the match help form a
cloud? Why do you need to secure the plastic bag onto the jar?
