This MIGHT have been my least favorite science
Project I’ve done to date, it just seemed to be a lot of work and wasn’t any cooler than baking soda in a tray, but here we go.
Ingredients:
•Baking soda
•dish soap
•food coloring
•vinegar
•pipette/dropper
We added 1 tablespoon of baking soda in to each cup of a 6-cup muffin tin then added several drops of dish soap to the baking soda and stirred it up until it formed a little ball.
We didn’t add enough soap at first so we had to add more. Once we formed the balls, we placed them on a plate and added drops of vinegar and watched it FIZZ 💗.
•Before we started with the vinegar, we discussed the hypothesis. “What’s going to happen?” “What will the vinegar do?” “Will it change color?”
•We also used the pipette to drop water on the colored baking soda balls. We wondered if it would change the outcome, of course it did.
Great fine motor practice for my little one who struggles in that area. She got frustrated at one point so we changed to a spoon which made it a little more exciting!
I keep the little droppers we used on hand for science experiments, since we do these a lot. I’ll link below.
