Dancing Frankenworms {Simple Science for Primary Classrooms}

I have been teaching a huge amount of science this fall and my kiddos {and their teacher} are having so much fun!

This one if floating around Pinterest in several places and I just had to try it!  Check out Playdough to Plato and Tunstall’s Teaching Tidbits for their take on this fun science activity.


The question behind this experiment is: Can we make gummy worms come to life?  Or for the not so Halloween version: What happens when you mix baking soda gummy worms and vinegar?

Here’s what you need: gummy worms, vinegar, baking soda, tablespoons/plastic spoons and clear cups.  I also use this lab booklet (available in my TpT store by clicking here).

My kiddos worked at their tables in small groups, but you could easily do this one whole group, too.

cutting worm

Start by cutting the gummy worms from head to tail to make skinny worms.  My firsties did this with minimal help, but the thinner the worms the better it will work, so you might want to pre-cut the worms with a sharp knife.

Next, mix 3 tablespoons of baking soda into a cup of water.

mixing in baking soda

Put your skinny gummy worms into the baking soda water and let them soak for 15 minutes.  During this time we wrote our hypothesis and read a book.

As they soak the worms created lots of bubbles, so we talked about how we could see gas inside of the liquid, t00.

transfering worms

After 15 minutes, scoop out the worms and put them into a clear cup of vinegar.  Caution: less is more here when it comes to the number of worms.  We got the best results with 2-3 worms per cup.


More waiting!  The magic doesn’t happen instantly…but it’s worth the wait!  I kept the kiddos entertained by spooning baking soda water into the vinegar and creating mini-eruptions.  Who doesn’t love an “explosion!?!”

Dancing Worms

Then comes the fun part!  The worms start to move and “dance” in the vinegar.  We set ours up and left them out for most of our literacy centers and they were pretty busy moving around the whole time!

Enjoy!  I hope your class likes this one as much as mine did!
