Blowing bubbles with our homemade bubble solution has been one of the girls’ favorite summer activities. However, halfway through the summer, our giant Dollar Store bubbles wands are beginning to fall apart. So this week, I decided to seize upon the girls’ favorite outdoor activity as a learning opportunity with a simple STEM activity. Using household objects to blow bubbles, it was also our first lesson in the scientific method.

A Simple STEM Activity

You remember the scientific method from your middle school science fairs, right? Question, hypothesis, prediction, testing and analysis. Big words for a preschooler, but when you think about it, simple concepts and much aligned with the way they naturally explore the world anyway.

Question

We started in the kitchen, where I took down our cooking utensil jar and told Big M we were going to use objects from the jar to blow bubbles. Our question? Which household objects would work to make bubbles?

Supplies

Assortment of household objects

Homemade bubble solution

Large bowl

Cost: Free to less than $5

Prep Time: Less than 5 minutes

Clean-up Time: Less than 5 minutes

Hypothesis & Prediction

Without delving into the complexities of bubble making, soap and surface tension, I asked Big M which utensils she thought would make the best bubbles. She quite confidently hypothesized the ones with holes would work best. She started sorting the utensils into two piles, making her prediction as to which ones would make bubbles.

Testing

We took the bubble blowing pile outside for testing. I filled a large bowl with our homemade bubble solution, and let her dip each utensil in and test it.

Analysis

We analyzed the results. She was most surprised that the whisk didn’t work since it seemed full of holes! She determined that bigger, circular holes made better bubbles than utensils with long, more rectangular slots.

Replication

Big M, my little scientist, then took things one step farther – she decided to search the garage for objects that might work. She came out with a fly swatter!

She was a little dismayed that with all its holes it didn’t make better bubbles – they were so tiny it took some serious blowing to produce bubbles with it, but when it did, made long bubble chains.

Not a bad first foray into the magical world of the scientific method! And Daddy was quite impressed with Big M’s newly expanded vocabulary. What simple STEM activity have you done with your kids this summer? Next time, try explaining it with the basic steps of the scientific method.
