Sunday Science/Baking Soda, Vinegar, Colors

It’s been awhile since we have played with any science experiments. The other night Selena kept asking for baking soda. It took me a while to figure out what she was wanting baking soda for. Then it dawned on me that we had watched an experiment on making a volcano. Since I didn’t have quite everything to make a volcano, I thought we would have some color fun.

We used baking soda, vinegar, and food coloring. I used a stir straw to pipe the vinegar onto the baking soda. At first Selena was not that excited, until I added a little blue food coloring so she could really see what was happening.

Now it was time for the fun to begin. We tried a little yellow food coloring and made green, then a little red. Selena thought the red was the neatest.

She kept asking for more and more. She finally grabbed the vinegar from me and poured all of it in the little dish, this is what we ended up with at the end. I liked the way you were actually able to see all the colors, red, yellow, blue, and orange.

We didn’t quite stop there, as Selena then decided to really give this a good shake or two until she got a little blue stain on her hands.

She was a little surprised that all her colors had blended together into this glob of almost black color.  She cried a bit about the blue stain, but I used this to reinforce this is why we follow directions. When Mama says “NO” she means “NO!”

No, Selena did not understand the full concept as to why the vinegar made the baking soda fizz but she had fun seeing all the different colors and called it her Tie Dye Experiment.
