It depends on the experiment.
In medical experiments to test the efficacy of drugs double blind tests are carried out to reduce the bias. This means the people carrying out the experiment and the people taking part have no idea who is being given the drug and who is getting the placebo.
In psychology experiments this is more difficult.
a fair test is were you only change one thing
A fair test is important so you can get accurate and unbiased results.
blowing up your head
A good idea for a science fair project is to do a project where you test which plant food will be the most effective. also, you can do which orange has more vitamin c. and who is the fastest kid in your grade or best speller.
Any test administered at a fair, such as a County or State fair can be described as a Fair Test.

More Reliable
yes, if u test it with regular bags, and green bags. i did this once at a science fair
The experiment is what you test and how you test it. Your entire project is based on the experiment.
We use fare test to prevent amuck up

Having a fair test in chemistry is important because it ensure the reliability and validity of the experimental results. By controlling variables and eliminating biases, researchers can accurately determine the effects of the independent variable on the dependent variable. This helps in establishing cause-and-effect relationships and drawing credible conclusions from the experiment.
