To get credit for this assignment, you must do the following:

1. Mix up a batch of bubble solution.

2. Use the wire to make five different geometric solids.

3. Draw a diagram of each shape that you have made.

4. Predict the way the bubbles will form.

5. Dip the shapes into the bubble solution and describe the way the bubbles have formed.

6. Answer the following questions.

A. Why do you see a rainbow of colors on the surface of a bubble? (Hint: It has something to do with the refraction and reflection of light)

B. Soap bubbles work because of something called
surface tension.Find out what surface tension is and write a brief explanation of how it works (Hint: The terms adhesion and cohesion may be helpful).

C. Using what you have learned about surface tension, explain why the bubbles formed the way they did in your geometric shapes.

D. How do you think that scientists are able to use the study of bubbles to solve engineering problems?

7. Hand in your diagrams of your geometric shapes, along with your predictions and results, and the answers to the questions listed above.

This assignment is worth 30 points!
