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
Procedures label the suction cups Label 1 suction cup p for plastic, g for glass and m for metal Place p suction cup on plastic and start timer Record data on paper with the marker Do the same thing with g and m suction cup Repeat 5 times
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.
