Science experiment:air exists

On Monday 21st of October we did an science experiment on air and how it exists. Here is something our class did to prove air exists. I hope you have fun doing this science experiment! :)

  AIR EXISTS

Equipment:  Container  filled with H20 (water)

                    Jar

                    Paper towel

Predict: Will the paper stay dry? I think the paper won’t stay dry. Why? Because the paper will be in the bucket.

Observe: The paper was screwed up a bit and it got put in a jar and the person holding the jar would quickly tip the jar into the water upside down. When he brang it back up, the paper didn’t fall out and it was totally dry.

Explain: The paper was dry because the paper was touching the edges of the jar from the inside causing it to not fall out of the jar and how the paper was touching the edges were because you screwed it up a bit, but if you screwed it up heaps, it would fall out. Also, if you hadn't of quickly tipped the jar into the water upside down, water would have got into the jar causing the paper to get wet.
