🧪 Part 1: Planning Your Investigation

1. What do you think makes a bubble strong and long-lasting? Circle all that you think are important:

Amount of soap in the mixture

Temperature of the water

Shape of the bubble wand

How gently you blow

Adding glycerine or sugar

2. Which bubble mixture do you predict will work best?

Water + dishwashing liquid only

Water + dishwashing liquid + glycerine

Water + dishwashing liquid + sugar

3. Draw the shapes of the three bubble wands your group will test:

4. Test each bubble mixture and wand combination. Record what you observe:

Mixture 1: _________________________

Wand Shape: _________ Bubble Size: _________ How long did it last? _________

Mixture 2: _________________________

Wand Shape: _________ Bubble Size: _________ How long did it last? _________

Mixture 3: _________________________

Wand Shape: _________ Bubble Size: _________ How long did it last? _________

5. Which combination made the strongest, longest-lasting bubbles?

6. Did the shape of your bubble wand change the shape of the bubbles? What did you notice?

7. Why do you think some bubble mixtures worked better than others? Use evidence from your experiment:

8. If you could test one more thing about bubbles, what would you investigate next?
