use a colourimeter to see how much light is passing through the solution
Trypsin is secreted by the duodenum (beginning of small intestine), where it breaks down peptides into amino acids, which helps the peptides (or proteins) better absorb into the intestines.
You can use any metal as a control, like steel. The experiment then becomes, "what metals conduct heat better than steel?"
sciencetist usally restart emperments to make sure they got it right so they do trial and error to see if there is a better solution
A controlled experiment is better than a none controlled experiment because you can control one of them and the other you can't. Science is a really fun subject.
Repeat the experiment and make sure it is fair.
actually wanting to do a science fair experiment?
it's important because that way you can organize your experiment better.
it helps for to have better sex with you
