Hello parents, teachers and students!
Are you looking for something fun to do at home that has a little bit of science behind it?
Learn how to make a cloud-in-a-jar at home with Meteorologist Sarah Spivey and her awesome assistant, David Sears!
Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it.
HERE’S WHAT YOU’LL NEED
- A mason jar with the lid
- Hot water
DO THE EXPERIMENT
- Pour hot water into the mason jar. Use adult supervision and avoid touching the bottom of the jar once the hot water is in the jar
- Quickly spritz some hairspray into the jar
- Quickly cover the jar with the lid
- Place a few ice cubes on top of the lid
- Watch as a cloud forms inside of the jar
- After a little while, lift up the lid and watch the “cloud” escape from the jar
HOW IT WORKS
This is a perfect example of how clouds form in our atmosphere. The hot water produces steam or water vapor in the jar. Then the cold ice causes the water vapor to condensate onto the microscopic hairspray particles.
SCIENCE WITH SARAH
If you’d like Sarah and David to come to your school and conduct a science experiment live on KSAT, email email@example.com.
