Conclusion:
From this experiment, my hypothesis was correct which was “The heart will beat
more after running because running requires lots of oxygen and blood to carry the
oxygen very fast. So heart will beat faster”. The heart did beat more after running then
before without having to run. The only only relationship would be that in the dependent
variable, it was the right way to measure it with two fingers either in neck or wrist
because it’s where we can feel the heart beat. I think our data is reliable because at first
we didn’t get a reliable data but went to redo it to get to reliable enough. I think that it
was hard to measure the heart beat because sometimes you will not be so sure about it.
Evaluation:
I think that the whole experiment work well in general because it was prepared
and it wasn’t a difficult experiment to do except for the running part. One part in the
method that went really well was going waiting for the heartbeat to recover because it
only requires us to rest. I wouldn’t change anything in the method because I think that it
was well done and it was a simple experiment so it wouldn’t have parts that were bad or
need to be changed. I think that next time that there would be something that we were
changing in the experiment because we had nothing to change.
