But the weather had changed! It had rained, so that led us to think about where the rain comes from?
Chloe: “The clouds – it falls out the clouds.”
The rain made puddles, and came from the clouds but how did it get into the clouds?
“The ice is very cold.”
The water is hot.
Our cloud is forming!
We carefully lifted the bowl away.
The cloud came out!
It felt cold and wet!
We couldn’t catch it! It was too light.
So a cloud is made of water that has evaporated (turned into a gas)from a source of water like a puddle or river or sea.Then it has gotten cold again and condensed (turned back into tiny wee water droplets) sticking onto miniscule bits of dirty air.
You can make a cloud too!
All you need is:
Warm water.
A large jar.
A bowl large enough to close over the jar when placed on top.
Some ice cubes.
Hairspray to dirty the air.
Spray the hairspray a few times into the jar and immediately close the jar by placing the bowl of ice on top. And just wait!
We started with the morning campus children thinking about the weather.
We went outside to see the weather.
We recorded clouds with the camera.
Look clouds!
Some clouds are dark.
Recording our questions, ideas and predictions in the log book.
We are learning to use the scientific method!
We made a cloud using dirty air, warm water, and ice.
Our cloud!
So we discovered you need warm water, cold, and dirty air for tiny water droplets to hold on to in order to make a cloud. It took a long time but Isaac kept watch the whole time. When the cloud appeared he called everyone over.
The cloud was tiny and hard to see when we lifted the bowl off. But it was there!
