Science Fun with Baking Soda and Vinegar

Science Fun with Baking Soda and Vinegar

My daughter loves to play with baking soda and vinegar. She always helps me deodorize the garbage disposal by pouring the vinegar down the drain and making bubbles.  Today my son got to watch and he was fascinated.

 

 

We were talking about how much she loved helping me and I remembered that last year she was obsessed with this activity I found on Pinterest (but unfortunately didn’t pin for some reason) where you put a bunch of baking soda in a dish and let the kids squirt different colors of vinegar on it to make a rainbow effect.  My son was interested so I though I would let them out on the deck to play with some baking soda and vinegar for a bit. I opted not to use dye since I had no idea if my son would actually play with it or if he would decide just to dump everything out and I didn’t want to deal with dye in clothing today.

 

 

This activity is super simple.  I just grabbed a couple of Tupperware containers, poured some baking soda in and leveled it, poured some vinegar into another Tupperware container and we were ready to go.  I got my plastic eye droppers off of Amazon last year. They are super easy to clean and I ended up giving some to a friend since the 12 pack was more than we needed. Since they are plastic there was no worrying about the kids dropping them and breaking them. I just rinse them out in the sink and we are good to go.

 

 

The reaction goes pretty quick since the eye droppers don’t hold a lot of vinegar. My daughter loved to make patterns in the baking soda and systematically covered her available space.  She is very focused when she works and it is always fascinating for me to watch her thought process.

 

 

My kids love bubbles so they had quite a bit of fun with it even without the dye.  I am probably going to let them use a lighter color like yellow next time since my son was pretty good about it. It makes the bubbles much clearer and if you give them primary colors it can help teach them the color wheel.

 

 

My son always tries to figure everything out and if there are other possible ways of doing them. Part of his process today was grabbing a handful of baking soda and dumping it into the vinegar container.  He was really pleased with the extra bubbles it produced! Most of his time was spent trying to scoop the baking soda with the eye dropper since he wasn’t quite able to squirt it with the vinegar.

 

 

We had some pretty patterns in the baking soda when we were done and the kids got to dump the rest of the vinegar into their baking soda containers which my daughter really loved to do! This baking soda and vinegar activity is one of the easiest and cheapest science experiments I have found to do with my kids.  I buy baking soda and vinegar in bulk at Costco (maybe $10 total for both) and there is enough for hours and hours of bubble making fun. If you were really creative you could even fill a bottle with baking soda and a balloon with vinegar, mix them together and see how the balloon fills with gas.  I may have to try that next time!
