Colorful and bubbly science exploration

Baking soda, food color, and vinegar are perhaps the easiest set of ingredients to throw together to create wonderful opportunities for science play and exploration. Today, our class explored these ingredients and the bubble making process in an entirely new way and it was big success…

I have written about using vinegar, baking, soda and food color before: “Fun with Colorful Bubble Science.”  In this post, the children enjoyed having the colors appear as they stirred the spoons of baking soda into the vinegar.  But this time, I changed the process so the children would be able to explore the process with more freedom and for a longer period of time…

  1. I set out trays for the children to work on.
  2. I set out cups of vinegar with food color added to each cup for the children to share.
  3. I set out one cup of baking Soda per tray.
  4. I set out plastic spoons and droppers.

  1. Each child scooped out a spoonful of baking soda on their tray.
  2. Then the children used the droppers to add colored vinegar on top of their scoop of baking soda to create colorful bubbles.

The children continued to add new scoops of baking soda and new colors of vinegar to make bubbles on the trays…

Some of the children announced that they were making volcanoes…

The bubble making process went on for quite some time. The children scooped and made bubbles, then scooped some more and made more bubbles…

I finally had to let the children know that we were going to have to get ready to go home but before we wrapped up our bubble making science process, I had each child choose one color of vinegar to set on their tray – and I added a second cup as well…

And we finished our day with a big bang!  All the children added the remainder of the baking soda into their cups of vinegar and we watched the bubbles flow!!

It was a terrific process of individual exploration and discovery plus the opportunity to finish with a big bubble finale!

    Looks like the children had tons of fun. I have not done this in a while, we must do this soon!

        I did this with my son this afternoon and he loved it! But after awhile he complained his eyes were burning. I think next time we will do for a shorter period of time but will definitely do this again!

          I am glad he loved it and hope he is okay too! I think that we explored this process a total of 30 minutes from beginning to end but that included our big finale. I know my students would have sat and did this much longer too but we had to wrap it up so they could go home!

    I think we will try this after we dye Easter eggs. We will already have the colored vinegar. I am not sure if the diluted mixture will work, but we’ll find out!

    • Deborah J. Stewart, M.Ed. says

      Well – I only use distilled white vinegar. I haven’t tried any other type so I am not sure if another type will work or not:) Might have to experiment a bit and find out!
