Ask a questionwhat you are wondering about (question)

Make a hypothesissimilar to a prediction, a statement about what you think will happen. You are trying to prove

it (prediction)

Conduct an experimentwhat you are going to do to find the

answer to your question (prodecure)

Collect datathis is what you notice while doing your experiment (data)

QuestionHow does the amount of soap in a solution affect the

time a bubble will last?

PredictionI think if you add more soap it will make a heavier

solution and the bubble will not last as long.

Materialsstraws (no sharing), stop watch, 6 inch plastic plate, 4

cups of solution (marked A, B, C, D)

Procedure1. Pour a small amount of solution onto the plate to

coat it.2. Place the straw just above the surface at an angle, and gently blow until the bubble fills the indented part of the

plate.3. Start the timer when the bubble reaches the

appropriate size. Stop the timer when it pops. Record time.4. Repeat, completing 3 trials for each solution, taking

turns.

Conclusion Questions1. How would you describe the bubble skin?2. What is inside the bubble?3. What was our manipulated/independent variable (the

one we were testing)?4. What was our responding/dependent variable (the one

we measured)?5. “Adding more soap always produces longer-lasting

bubbles.” Agree or disagree? Explain.6. What are you wondering now? If you had to do a

similar experiment, what would you like to find out?
