Everyone has participated in the oh so familiar science experiment of baking soda and vinegar; the two mixing together and bubbling and fizzing so rapidly we all jump up and down and joyfully watch the ingredients “explode!” This project is chemistry at its most basic level, and yet so new and magical in the eyes of a three year old.
Instead of pouring the vinegar into the baking soda for a one time explosion I go about this project a little differently. I line a pan with a thin layer of baking soda and then arm the kids with eye droppers – Side note I recently made a purchase from discount school supply and was so excited to get my new eye droppers and liquid water colors, I usually try to use ingredients found around the house for most of my projects but these items are so useful! – Next I fill small cups with vinegar and then add color, you can use food coloring or liquid water colors.
The kids work on fine motor skills and improve their hand coordination, great for pre-writing, when using the eye droppers. They watch the colors bubble and pop while working on covering all of their white from the baking soda. When all of the chemical reactions have been used up and there are “no more bubbles” My little ones always do a bit of color mixing and of course can’t get through an activity without a little sensory exploration! This time in the form of running their hands through the sludge. This is by far one of my favorite activities it keeps the kids engaged for a seriously long time, and I love the conversation that comes about as we’re making mini colorful explosions!
