Science Buddies: "Ask an Expert"

One of my science fair ideas requires the use of humans, but what would I do with the variables involved? Such as when that person woke up, what they ate, how many steps they took when walking, etc etc etc. Is there anything I can do about this?

Hi aznkarson,

Can you please post a few more details about your project? What exactly are you testing?
Some of the variables you are concerned about may be negligible and others may need to be regulated, but all this would depend on what your project is investigating.

Thanks,

Hi aznkarson,

I also agree with the previous expert that if you provide more details about your project, we will be able to give you more helpful advice. What is your main question, what is the hypothesis you're testing, and what method are you going to use to test your hypothesis? For certain questions, it may be important to keep the factors you mentioned as consistent as possible between your test subjects, but for other questions, it may not matter all that much if those factors are different.
