The Bubble Experiment

Recently, we had the opportunity to join the Crest Science Challenge, and we decided to team up with two home ed families who were also taking part. The children work their way through a vast array of hands-on experiments, coming up with hypotheses and making observations. It can be as formal or informal as we want to make it. Our children in our little “science club” vary in age from one to almost ten. Whilst the youngest two tend to just do their own thing, the other five all pitch in together and it’s lovely to watch.

In our first session, we experimented with bubbles. We put together a collection of commerical bubble solution as well as some ingredients to make our own; lots of different shaped wands, bowls and saucers, straws and anything else we thought might come in useful.

We asked the children to look at the wands we had – would a heart shaped wand blow a heart shaped bubble? Would all the bubbles from a particular wand all be the same size? Could we do anything to affect the size of the bubbles?

Theories made, they set to work and we had great fun. What did we learn? A bubble is round, no matter what shape the wand. Except if you can get the bubble to pause within the wand and then you can have a shaped bubble. Different size bubbles can come from one wand, and we can make a difference by changing how hard we blow.

The two girls loved finding out that they could make lots of bubbles quickly by blowing into the mix with a straw instead of blowing mix through a wand.

And we all discovered that bubbles can make a lot of mess!
