A manipulated variable. (Apex)
A hypothesis is not a variable...it is something that you think will happen based on reasoning and observations, before doing an experiment.
The dependent variable.
the manipulated variable is the part of the experiment that is changed. the dependent variable is the part of the experiment that does not get changed(stays the same throughout the experiment), and the scientist use it to record the data.
It is what you expect to happen before you actually carry out the experiment, based on the knowledge and theory you already have and know. *called a hypothesis

Well, it depends on your experiment. If you're adjusting the amount of cooking oil before an experiment, it's an independent variable. If you're calculating how much there is after the experiment, it would be a dependent variable.

The dependant variable in this experiment would be the amount of 'crying' resulting from the cutting of each onion.
An experiment is the thing that you perform, and a hypothesis is the guess you make at the start (before the experiment) to determin what's going to happen.

You want to have a hypothesis to test. A hypothesis is kind of like a reasoned guess what you expect to happen. The results of your experiment will either support your hypothesis or it wont.
The Independent Variable : It is the ONE thing you plan to be different in the experiment. You decide on what is going to be different BEFORE doing the experiment. Dependent Variable or Outcome Variable : It is the result you compare of measure in the experiment. Controlled Variable : This is the part of the experiment that you DO NOT CHANGE. This is what STAYS THE SAME.
To eliminate confounding variables, or variables that were not controlled and damaged the validity of the experiment by affecting the dependent and independent variable, the experimenter should plan ahead. They should run many checks before actually running an experiment.
If the answer is already a well known scientific fact, it would be a waste of time to do an experiment. It also helps you know what additional items you may need to do an experiment.
