I believe that every child used to have
a dream to be a scientist, at least I do. When I was young, as soon as my
parents asked me which job I would want to do in future, I would say:
“Scientist!” I guess it was not because how much I love science, I think it was
because every child thinks that to be a scientist is a really cool and fun thing
to do, and so do I. As time goes by, I changed my ambition for so many times,
but I always remember that little girl wearing “glasses without lens” and said
out loud: “I want to be a scientist!”
Although now I am not interested in
being a scientist anymore, I’m still interested in doing some fun little
experiments. Last summer I bought a book called <Water knows the answers>,
but since last summer I was too busy to read the book and make the experiments
come true, this summer I eventually got a chance to read this book and conduct
the experiment by myself.
I have chosen a pretty simple
experiment, which only required a glass of water and paper. This was an
interesting experiment, on the book it said: “Step one. Fill up the glass with
water. Step two. Put a paper on the glass and cover the rim of the cup. Step
three. Make the glass of water upside down, now you can see that this particular
paper holds the entire glass of water, how amazing it is.” I followed all the
steps on the book, but it turned out that even an experiment which seems simple
would not be that simple.
The first time I put my glass upside
down, the water quickly fell all the way down. I was confused, because I
followed all the steps exactly on the book. Then I thought maybe it was because
the water wasn’t fill out, and there was still some emptiness between the glass
and the paper, so I decided to fill out the glass with more water this
time.
But after the second experiment, my
hypothesis was broken by the results of the experiment – the water still fell
down. I started to think where I went wrong. I checked the glass; there were no
cracks or nicks on the glass. I checked the paper I used, it was pretty thick –
better to fit every experimental needs. And I checked the rim of the glass
again, and then I found where the problem was. The glass I used has an archy
edge, which made it hard to make the paper and the glass do not have any nicks.
So I changed a glass, and tried again all the steps.
This time I succeeded! And it turned out
that my assumption was right! And through the two fail experiments, I also got
the principal of this experiment, the only reason why the paper wouldn’t fall
down was because the atmospheric pressure.
To conduct an experiment was such a fun
thing, and maybe next year I will try again!
