Rainbow Reactions

It is no surprise we love mixing things up, testing concoctions, and making crazy experiments. There rainbow reactions are no different! If you are looking for a great activity to test prediction and learn about chemical reactions, you’ve come to the right place!

Setting up the Experiment

For this project, I gave the boys the problem of trying to make reactions that we could see and compare. We wanted to record our observations and attempt to make the biggest reactions by mixing a variety of ingredients together that we “thought” would create a bubbling chemical reaction based on what we already knew about the combination of these ingredients.

We decided to color code the different reaction to make it easier to compare and contrast the different mixtures. We even made a simple hand drawn chart of our ideas and our predictions for what we thought would happen.

Materials:

Baking Soda
Flour
Alka-Seltzer Tablets
Citric Acid

Vinegar
Water
Food Coloring

Test Tubes
Corks (optional)

Creating Rainbow Reactions

The idea behind this activity is to try a variety of mixtures and solutions. We used ones the boys created on their own, but please do not limit your thinking or ideas to what you see here! When we set out, we thought we could make our corks FLY down our sidewalk, but we quickly learned our corks were too porous and let out too much air. We simply adjusted and made it so our reactions overflowed onto the paper, still creating some pretty awesome art!

Here are some of the examples of what we made. {We had some major technical difficulties this week in the form of a certain toddler pouring water all over my computer. Therefore, we weren’t able to get all of the images and videos loaded that we took for this experiment. Hopefully, I can get those updated soon!

Rainbow Reactions with Vinegar and Flour

Water + Citric Acid + Flour – No Reaction
added baking soda…. Instant Reaction

As I mentioned before, we continued with these making concoctions and potions to represent each color of the rainbow. Poor Camera 🙁  However, at the end of everything, we had a pretty amazing sprawl of reaction mess.

  3. Love the charting component of this experiment. It takes the learning into a whole new direction, especially when the kids come up with it themselves. Looks fun!

    I can’t wait to try these explorations with my grandchildren. Thanks for the great ideas.

  5. Glad you had fun with all the fun reactions and so sorry about your computer!!
