Science fair question!! answer only if y KNOW what u r talking about!!?

Question

OK

My science fair idea:
have 7-10 boys and girls take the same pop quiz, buta different times. i want to c if there is an increase in heart rate before i take the pressure. WILL THERE B A VISIBLE INCREASE WHILE TAKING A TEST???

i asked other people, its 50/50 might, might not.

i need to know if it will work!

Answer 1

There will be an increase in heart rate in those who are pressured by taking a test (want to do well, afraid of failing). But for some, they will not feel any pressure to do well, and so they will not have an increased rate.

Answer 2

The point of a science fair project is to investigate your hypothesis. It doesn't matter what the results are, it matters how you go about your investigation and how you present your results. I personally wouldn't do a question like this since you would have to get your hands on an ekg machine, etc. Plus you would have to survey each subject to assess whether their health is an issue. You would have to follow the subjects around with ekgs repeatedly to establish a statistical baseline heart rate. You would also have to make sure the pop quiz actually had a bearing on grades or else you would not get any results for this (no one gets stressed about a test that doesn't matter...). After this you would have to address MANY possible sources of error/lurking variables/etc. Too much work.

Answer 3

Depends, if you are doing a quiz/survey at a mall or going to certain subject teachers and asking them a favor. I think you should see a significant increase in several people, especially if the pop quiz is difficult and they are told it is worth something. Also, IQ may be a factor in how some students react. You should get results, I would do 20-25 though for a better and more accurate sample.

Answer 4

if its an important test then it will, butif its just some test, chances are it will not.
one idea that is good for a science fair is:
stand on a street corner by a stop sign and see who does not come to a complete stop. record the ages, sexes, races, type of car, gather up all the data, make a chart showing who is most likely to not stop. this worked for me and it got the attention of county officials and they put a light where the stop sign once stood. it is a sociology part of science. and it definitely beats the volcano project. or you can do it with people with cell phones while driving.

Answer 5

There would be no sure way you can depend on the results. There are simply too many variables. Look for a different idea, in my opinion. Best of luck.
