Weather Science β˜οΈπŸŒ§πŸ’§

I hope everyone has been enjoying science as much as I have these past couple of months! I have received some feedback and have decided to include, in this blog, a detailed process of our experiments for those little scientist out there that would like to recreate the process at home, with a little help.

“Cloud in a Jar”

  1. Glass jar with lid
  2. Measuring cup
  3. Hot water
  4. Hairspray (we called this our magic dust particle spray)
  5. Ice cubes 

Heat water up in measuring cup (you will want approximately 1/2 the glass jar filled with hot water). Pour water into glass jar.

Immediately spray hairspray into glass jar. This give the water a surface to condense onto, similar to the dust and debris found in the air.

Invert the lid of the jar in order to hold the ice and place on top of the jar. You will see the cloud begin to form within the jar. You may “let the cloud out” and try this multiple times without having to reheat the water.

Make it Rain” 

  1. Large glass or plastic container
  2. Shaving cream
  3. Eye dropper
  4. Blue food coloring & water solution to represent rain.

Now that we are aware of what makes up a cloud we are now able to think about why/how it rains.  
As a visible cloud gathers more and more tiny droplets of water it becomes heavier and heavier with the water droplets.

Fill your glass or plastic container 2/3 full with water.

Place shaving cream on top to represent a cloud.

Use eye dropper, (filled with blue food coloring solution) to fill the cloud with excess water, making it heavier and heavier until it “rains”.

We also watched this video that emphasized the concept:

What is a cloud?
