Objective: Students will use the properties of different liquids to make a bubble mixture that produces large buubles.
Scientists study liquids and gases. How does the amount of soap compared to water affect the size of a bubble?
PROCEDURE
1. What do you know about bubbles? Predict if more or less soap will produce a bigger bubble.
2. Plan a bubble mixture. Use a graduated cylinder to pour 100 mL of water into a plastic cup. Add 25 mL of liquid soap to the water. Stir the mixture. Record the contents of the test mixture in the chart.
3. Use a bubble wand to test your mixture. Record your observations.
4. Revise your bubble mixture and repeat the process. Use the graduated cylinder to pour 100 mL of water into a plastic cup. Add 50 mL of liquid soap to the water. Stir the mixture.
