Science Experiment!

Posted by on May 7, 2020

Did anybody else get taken by surprise with a thunder and lightning and RAIN storm the other night?? Over at Miss Cobbett’s house, it was very loud – and very wet!

It got me thinking a little bit about how rain gets made in clouds. Here in Burnaby we see it raining a lot, but we don’t get to see what it looks like up in the clouds before it starts to rain….to investigate what that looks like, Miss Cobbett did some research, and came across a fun experiment you can try at home!

All you need is:

-a cup filled up pretty high with water

-shaving cream

-blue food colouring (though, any colour you have already works just fine!)

I made a quick instructional video you can watch here to see what Miss Cobbett’s homemade rainstorm looks like! What do you think would happen if I had added even more food colouring? How long do you think I waited for the rain?

Practice patience, and see how long it takes for the rain to make its way down through your clouds! You might have to add a few extra drops on top if it’s taking a really long time, but have a conversation about how long you think it will take, and then time it! How much rain do you think you’ll have?
.
Make some predictions together, and then record your conclusions once you’ve finished cleaning up your experiment! Careful not to get any food colouring on your clothes, in case it stains – and have fun watching your very own rain storm!
