Looking at bubbles...

Scientific Concept:

A bubble is just air wrapped in soap film. Soap film is made from soap and water (or other liquid). The outside and inside surfaces of a bubble consist of soap molecules. A thin layer of water lies between the two layers of soap molecules, sort of like a water sandwich with soap molecules for bread. They work together to hold air inside.

For the first science club activity we looked bubbles and how we could blow the best bubble. After discussing what we knew about making bubble mixture and the scientific concept behind bubbles, we got to all have a turn blowing bubbles. We each had a pipette with the end cut off to blow through and tried to work out the best way to blow a bubble. We also experimented with what happened when we added more dishwashing liquid to the solution.

We then came back together to think about what would happen if we added glycerol to the solution. Ask your child what they observed!
