This year, Hubs made a New Years Resolution to do a STEM experiment every month with the kids. For the first quarter, we are focusing on a variety of Earth Science. I saw a pin of kiddos making clouds in a jar and thought this would be a good jumping off point so we gathered up some materials and Hubs got down to teaching them about clouds and how rain works.
To get started, you’ll need some glass jars, some shaving cream, water, and liquid food dye. Hubs started by pouring water 3/4 the way in a class and then topped it with shaving cream. We talked about how clouds “float” in our atmosphere and how they are able to do that. Then, they kids picked out some food dye and started seeding their clouds.
How much more “water” would be needed until rain started to fall? Let’s see!
We had 2 techniques: slow and steady and all in.
Piglet seeded his cloud quickly and his cup starting raining almost immediately. Blueberry went a little slower and her cloud didn’t even start to rain. We talked about how more humid places have more water in the air and thus rain more. Colorado is like Blueberry’s cloud and has a hard time raining.
We also talked about the atmosphere and how it has different layers and how humidity or wind can affect the amount of rain that falls.
Since Blueberry’s wasn’t raining, we decided to make a “front” come in and she stuck her fingers into the cup. Once the cloud was agitated, rain started to fall!
Overall, the kids had a lot of fun. They knew more about clouds than we expected and I am excited for next month’s activity!
