To find different possibilitys and the overall solution through trial and error
An experiment can be use to gather informations because in this way we test different things to know if it is true or not and while discovering new things we can also gather informations from the given theme
We use fare test to prevent amuck up
Use same equipment/apparatus

If the drinking is recent, and if the test includes a screening for blood alcohol level, then you may fail. Different tests screen for different things. If what you use is NOT part of the test in any way, then what you use will not be detected.
It is important to use the same amount of water each time you conduct the experiment because if you change more than 1 thing in an experiment, then you can't know the true result because you tested too many things. You need all controlled variables in an experiment except for 1 manipulated variable.
The reasoning of proving whether the experiment works or not, is acceptable or not, is reasonable or not.
Observation
Use two bowls with different upper surface but the same volume; measure during time the mass.
Scientist design experiments to test something.
to help researchers conclude that results are related to the new drug and not to the orange juice <APEX> ^_^
To ensure an experiment is a fair test in chemistry, you should control all variables except for the one being tested. Use identical conditions for all trials, measure with precision, and replicate the experiment to ensure reliability. Randomize sample selection and use a control group for comparison.
