Which Washing Up Liquid Creates The Most Bubbles?

2nd class were doing a STEM investigation this week. They looked at four different types of washing up liquid and had to investigate which one created the most bubbles.

In order to make it a fair test there were a lot of factors to consider. How much water? How much liquid? How will we create bubbles? How will we measure the bubbles? What constitutes as most?

We had a great time with this investigation.
