Indoors: Do an alphabet scavenger hunt. Find something that starts with an A like an apple. Then look for a B like a book. See how many letters you can get.
Make a Cloud in a Jar Spring is known for its rain, which comes from clouds. But how does a cloud come into being in the first place?
Clouds are formed when liquid water on earth turns into a gas called water vapor (this is called evaporation). The gas rises high into the air where the temperature is cooler than on earth. The water vapor then collects into tiny droplets of water (this is called condensation) and forms a cloud by attaching to particles in the air such as dust. In this fun project, you will make your own cloud using hairspray for the water vapor to attach to.
Here’s what you’ll need:
Glass jar with a lid
Hot water (have an adult help) – you need enough to fill about 1/3 or 1/4 of the jar
Hair spray (or deodorant spray)
And here’s what to do:
Remove the lid, turn it upside down and place ice cubes in it. Keep it handy.
Have an adult get hot water and pour it into the jar. Swirl it around to warm up the air in the glass.
Quickly place the lid with the ice cubes in it on top of the jar.
Wait 30 seconds.
Take the lid off, spray hairspray into the jar, and then quickly put the lid (with the ice in it) back on.
Watch the cloud forming.
When you see a lot of condensation form, you can remove the lid and let the cloud go into the air.
What happened in this experiment?
In this experiment, the hot water you added to the jar caused the air inside to heat up. This caused some of the water to evaporate and turn into water vapor. When you put the ice in the lid on the top, you cooled the warm air and caused the water vapor to to condense onto the hairspray particles – which formed a cloud.
