Controls are used to show that the test, equipment, procedure...are working properly. One would expect negative controls to give negative results and positive controls to give positive results. Controls used would depend on the experiment.
it's better to have a control but no you do not have to have a control in a science fair project
it is a variable that you allow to stay the same throughout the experiment.
a control group is a sample that is treated like the other experimental groups except that the independent variable isn't applied to it
A well designed science fair project should have one independent variable, one dependent variable, and lots of factors that are held constant as you repeat the experiment several times to verify your results.
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.

Any specific measurement or quantification of a variable.

In a science fair project, independent variables are the factors that are manipulated or changed by the experimenter to observe their effects on the dependent variable. For example, if a project investigates how different amounts of light affect plant growth, the amount of light is the independent variable. It's crucial to control other variables to ensure that any observed effects are due to changes in the independent variable alone.
i need a friken science fair project
what can i do with yeast for a science fair project
When some thing stays the same.
