The Bubble Experiment:
Questions: How are bubbles made? Which solution makes the biggest bubble? How can you tell when a bubble will pop? What colors do bubbles produce? Why? What is soap?
Materials: (4) vials, (2) 1 mL spoons, glass jar (dishwasher soap), plastic jar (water), (2) eye-droppers, lab worksheet, classroom clock, (2) rulers, masking tape, pencil, straws
Procedures:
1.) You will work as a lab table. Make each solution first! Use the water in plastic jar and use dishwasher soap in glass jar. Make one solution per vial (4 different ones).
2.) a.) Put 10 mL of water in vial using eyedropper.
b.) Add 1 mL soap in vial using the 1 mL spoon.
3.) a.) Put 10 mL of water in vial using eyedropper.
b.) Add 2 mL soap in vial using the 1 mL spoon.
4.) a.) Put 10 mL of water in vial using eyedropper.
b.) Add 3 mL soap in vial using the 1 mL spoon.
5.) a.) Put 10 mL of water in vial using eyedropper.
b.) Add 4 mL soap in vial using the 1 mL spoon.
6.) Follow procedures on Lab Sheet for “Lasts the Longest:
I.) Test each solution (3) times.
II.) Record time it takes for bubble to pop.
III.) Answer questions after done with all three tests.
7.) Follow procedures on Lab Sheet for “Biggest Bubble”:
I.) Bubbles need to be about the same size.
II.) Make a 6-inch bubble on the desk between tape marks on desk.
III.) Four students should blow bubbles at the same time on same desk, using the same solution.
IV.) Record the diameter on ring left behind from popped bubble in (cm).
