I mentioned last month that I’d post some things I do for my preschooler while I’m busy working with my older two and this one is a big hit. The first time I did this I used squirt bottles instead of eyedroppers and I’ll tell you right now, just get some eyedroppers. It makes the activity more fun and you will find countless other uses for them.
Pour out a box or two of baking soda into a medium/large container. Pour plain white vinegar into small containers and use food coloring to tint each one a different color. When Wee One #3 saw the baking soda fizz and poof up, she was sold. She played around with this for almond an hour. Then, she found another way to play with it! She asked for a tiny spoon, so I gave her my 1/4 teaspoon and she started scooping the baking soda out of the tupperware and plunking it into the vinegar. Check out the blue vinegar in the last row of photos for an action shot of that. Much bigger fizz! Of course dumping baking soda into vinegar isn’t as much of a time sink as the other way around, but it rounded out another half hour and I was able to start to finish a grammar lesson for my 2nd grader and a math lesson for my 7th grader and my preschooler happily experimented alongside us.
She has asked to do this activity over and over again also, so it’s definitely a repeatable activity!
