Any baking soda and vinegar experiment I’ve ever done with the kids has always been a success. The fizz just makes it so much fun!
Henry was fascinated by the reactions the colored vinegar made when it hit the baking soda in this activity.
This science experiment, that I found at The Adventures of the Smith Family, was super easy to set up.
Just spread out some baking soda on a cookie sheet and add color to some vinegar!
While I was coloring the vinegar, I let Henry have some experimental play of his own with the baking soda first.
He liked to see the prints his hammer made when he hit it.
I suggested dropping a golf ball in the mound of baking soda, hoping to make moon craters. He didn’t find that as fascinating as the hammer though.
During his experimenting, I simply poured vinegar into three small dishes. And added a few drops of food coloring to each.
I handed Henry a few different choices for droppers: an old medicine syringe, a dropper and a large turkey baster. That’s what I had on hand to use.
I loved seeing what those little fingers were doing as he sucked up and squirted the vinegar in each of the droppers. They’re all great for fine motor skills.
We also tried to reverse the science experiment by adding baking soda to the vinegar.
We experimented to find the perfect ratio of baking soda to vinegar for the best reactions, find out what it is!
Henry wasn’t thrilled with this because it didn’t work nearly as well.
Watching the baking soda fizz as the vinegar hit was exciting! Seeing the colors mix together was pretty neat too.
Henry continued until every last drop of colored vinegar was used.
Even then he started sucking up vinegar from the cookie sheet to squirt it again!
Even though it looks like there may have been some sensory play going on, I don’t believe a finger even touched the pan! I was amazed that Henry could keep his hands off. I think the designs were made by dragging the dropper through the baking soda.
