If you’ve been following along with our Tot School Days, then you know our theme for this month is Science Lab. If not, what are you waiting for? You can check out all the awesome stuff we’ve been up to here.
The little guy and I are definitely lovin’ it! And of course we’ve been getting all kinds of creative with things too. One of our favorites this week was a new twist on an old favorite. We’ve all experimented with baking soda + vinegar. I mean, seriously… Who hasn’t, right?
When I saw that one of our activities was baking soda + vinegar reactions, I got a little giddy inside. I totally remember doing this as a kid and I thought it’d be awesome to share how we created our rainbow reactions with baking soda + vinegar.
This is such a fun process art project for little kids. And seriously… What little kid doesn’t love a little bit of art mixed with a lot of science?
What you’ll need
- Food Coloring
- Baking Soda
- Cookie Sheet
- Small Dishes
Here’s how to do it
We mixed food coloring and vinegar in small dishes to create each of the three primary colors. We ended up using a small acrylic tray we got from the dollar store, but you could also use an ice cube tray or small dishes. Whatever you have works.
After that, we poured a thin layer of baking soda onto the cookie sheet. We used between a half and a whole box of baking soda each time we did this activity.
Use the dropper to add the food coloring and vinegar mixture to the baking soda and you have yourself a rainbow reaction.
Don’t forget to ask your little kids what they think will happen when they combine the baking soda + vinegar. You never know, their answers might surprise you. I’ve seriously had that happen with my toddler class. I’m thinking there’s no way a 2-3 year old is going to know and guess what? Yep, they totally do.
The baking soda and vinegar create a chemical reaction that bubbles. It’s definitely awesome and little kids love it. The little guy kept saying “more bubbles.” At barely two, he doesn’t quite understand the chemical reaction, but this was still one of his favorite science experiments this summer.
We actually did this activity quite a few times. It’s quick and easy to set up and of course to clean up too.
There are so many different ways to create this type of chemical reaction. I’m sure this is something that we’ll be doing over and over again.
You’re definitely going to want to try this out with your little kids. It’s seriously too awesome not to.
