If you haven’t seen our amazing new resource, Water Cycle Unit Study: Why does it rain?, then you’re absolutely in the right place for your next project! I told you about all the rain we’ve been having lately, and how my five-year-old is always asking, “Are the raindrops finished yet?“
Hopefully, this Water Cycle Study may help our little homeschoolers have a little more understanding of why it rains and how important this cycle is for our ecosystem. This rain cloud experiment shaving cream is perfect for before or after the study. You can use it as an intro to the study or as a fun activity after!
This science experiment is so easy but can get pretty messy, so be sure you’re prepared. Of course, the kids totally love the mess though. I’m a child at heart, so I have to be honest. The messier, the more fun in my opinion. But then I have to clean up the mess too so…….
How to set up the experiment
It takes just a few simple components that you probably already have in your pantry. Notice I put a large clear bowl as one item, however, some people use a jar instead. This idea is for you and your kids to be able to clearly see the the rain cloud begin through the unit study water cycle process.
In order to conduct the rain cloud experiment, you will need a few materials. These include:
- a large clear bowl or a container you can see through
- Baby Oil
- food coloring
- foaming shaving cream
And I’m not sure exactly who came up with this experiment first, but we’ve thrown a new spin on it by adding the baby oil!
Because water and oil don’t mix, the baby oil sits on top of the water creating a clear barrier between the shaving cream and the water. This barrier allows you to watch the “rain” fall in “drops” into the oil, then stream down through the water. It’s such a neat rain cloud experiment shaving cream style, right?!
The more oil you add, the bigger the clear barrier, and the better view you will have of ‘raindrops’. I suggest a large barrier so that little eyes really get to see the action happening. The photo below is our baby oil barrier. Johannah kept adding her drops in the same spot in hopes of creating a hurricane, hence the very large bubble.
The steps of the rain cloud experiment shaving cream are just as easy as gathering the ingredients. Fill your bowl about halfway with water then add as much baby oil as you would like for your barrier.
Wait a minute or two to be sure that the oil and water fully separate, then start your shaving cream cloud. Basically, just smear it all over the top of the water – it will do the work for you.
Again, let a little settling happen. While you’re waiting, gather a small bowl, fill it with water and add your food coloring to your desired rain color.
Now you can take your pipette, fill it with colored water, and begin filling your rain cloud. Just stick the tip into various places in the shaving cream and watch as it grows and colored water drops begin to fall as rain.
Observe and record the experiment
Once the rain cloud experiment is set up, you can observe what happens. The shaving cream and food coloring will create a rain cloud, and the addition of water will simulate rain, along with the baby oil.
Be sure to watch carefully as the colors mix and rain falls!
You can use the sheets inside of the below unit study that includes this experiment to record your observations and even your hypothesis of what your kids think will happen.
If you’re serious about taking the next step after this science experiment, I have the perfect little ebook for you! The Water Cycle Ebook is a 10-page digital download that explains the water in an easy to understand way. Follow along the pages to learn more about how rain affects our lives!
