Gravity Free Water
what goes up must go down
Ask my Question
What affect does gravity have on the cardboard and the water
Form my Hypothesis
If I fill the glass up with water,then air pressure will cause a piece of cardboard to stick to the cup
Plan my Experiment
Material
glass of water
A piece of cardboard
Steps
1.fill the glass up to the top
2.put the cardboard on top of the glass
3.tip it over and let go
Conducting my Experiment
Trial 1
18.78
It held for a long time because air pressure was pushing up on the cardboard
Trial 2
9.00
It held not as long but the air pressure still push it up
Trial 3
4.00
it held not at all it fell just like that air pressure did not help
My conclusion
I would rather us glass then a plastic cup
My hypothesis was correct the cardboard did stay
My hypothesis was correct the cardboard did stay
