Question
Do suction cups stick equally well to
different surfaces?
Hypothesis
I predict that the suction cup will not stick
equally well to each surface because
suction cups stick differently to different
surfaces. The smoother the surface the
longer it sticks.
Materials
3 suction cups
Metal
3 3ounce weights
Glass
Plastic
Paper
Marker
tape
timer

Conclusion
My prediction was correct. it does not stick
equally well to different surfaces because the
highest time for glass was 20 minutes, metal was
5 minutes and plastic was 5 minutes. Therefore
the times were not equal.
