This lesson plan gives you a fun hands-on lesson all about bubbles. All you need is some bubble mix (which there are instructions for you to make your own included in the lesson plan) and some other bits that should be readily available around the school or home.
Dependent on the number of bubble wands/household items you have available to use for the experiments and the extension activities, the session can last between 30-50 minutes. It is entirely flexible.
My children loved this one and really enjoyed predicting the shapes etc
