1. Touchy Bubbles

2. On which surface will a bubble last the longest?
Problem
On which surface will a bubble last the longest?

3. Surfaces we will be testing
Table top
Construction Paper
Aluminum Tray
Plastic Tray
Wax Paper

4. Hypothesis IF I blow a bubble on different surfaces
THEN the bubble will last the longest on ________________ surface
BECAUSE _____________________
_______________________________
Choose from Table top, Construction Paper, Aluminum Tray, Plastic Tray, & Wax Paper

5. Variables Independent Variable (you change): Surface
Dependent Variable (you measure):
Surface
Time the bubble lasts in seconds

6. Materials 1 cup of bubble mix 1 desk top 1 aluminum tray
1 plastic tray
1 piece of construction paper
1 piece of wax paper
1 bubble wand

7. Procedure One person will blow a bubble on the first surface.
As soon as the bubble is complete, another person will start the stopwatch. Click here for an online STOPWATCH to use.
Measure the length of time the bubble lasts in seconds and record on your data chart.
Repeat steps 1-3 two more times for the first surface.
Find the average or mean of the 3 attempts and record.
Repeat steps 1-5 for the rest of the surfaces.

8. Data Table Surface Time for 1st Bubble to Pop (seconds)
Time for 2nd Bubble to Pop (seconds)
Time for 3rd Bubble to Pop
(seconds)
Average or Mean Time (seconds)
Table Top
Construction paper
Aluminum Tray
Plastic Tray 
Wax Paper 

9. Use a ruler and color!

10. Conclusion
Was your hypothesis supported? Why or why not? Use data to defend your answer.  
Identify any possible errors or factors that could have affected the experiment.  
Is there anything you would do differently next time?
List at least three other surfaces you could test to see how long a bubble would last.
