Bubbles - Hands on Challenges
Great activities from Barbara Duckworth and Jill Mitchell (Wild daisies).

What makes the best bubbles?
Experiment with detergent, shampoo, bubble bath and liquid soap.
Present your findings on a chart.

How strong are bubbles?
Blow through a straw into a glass that contains some bubble mixture.
Carefully pull out the straw.
Now put the straw back into the glass without breaking the bubbles.

What objects can you poke into the bubbles without breaking them?
Share your findings with the class.

What would happen if all the bubbles made didn't burst? (A 'hot' question - see entry 27.04.06)

Blow through a straw into a glass with a strong bubble mixture.
Can you blow bubbles so that they flow out of the glass and onto a plate?
Who can fill the plate?

Can you make a bubble picture?
Mix 1 teaspoon of food colouring and detergent with some water.
Blow through the straw to make bubbles
Place paper over the bubbles to make a print.
Experiment with other colours.
Display your print.
