What is the difference between variable constant and control?
A constant is always fixed and won't change in an experiment. The control is the standard that you are testing against to see how experiment outcomes change when the testing factors are altered.
Are controls always necessary in an experiment?
Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results
What is an independent variable in a science fair projects?
An independent variable is the same thing as a test variable, so it is what you are testing. If you want to find out which chocolate is more fattening, you are TESTing to see if Hershey's or M&M's. You are TESTing the chocolate (to see which is more fattening)
Which factor is the dependent variable in an experiment?
The dependent variable is what the results yielded. For example, if you are testing humans, the dependent variable will be the test subject's answers. Some people also say it is what you are testing for if it is not testing on humans. For example, "the differences in growths of bacteria".
What are constant variables and y r they important in an experiment?
. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly

What are two variables held constant when testing boyles law in manometer?
Temperature & mass keep constant in Boyle's law. Volume and pressure are variable.
What are you testing in an experiment?
You are testing the independent variable. The dependent variable is the one being measured.

A sentence for independent variable?
i am testing a independent variable for my plant it was worth
What are control and variables?
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
Is the independent variable changed?
In an experiment your independent variable does change to what you choose. An example would be an experiment testing to see if the amount of water in a pot effects the amount of time it takes for the water to boil. Your independent variable would be the different amounts of water used. Your dependent variable would be the time because it depends on the independent variable (the amount of water used) . Your constant would be the temperature because it is not changed throughout the experiment, and thus remains constant. This way you can isolate which changes affect which variables.

What are variables and uncontrolled variables?
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.

An experiment testing the amount of sunlight that is best for growing plants a plant that receives no sunlight at all may serve?
its either a constant or a control im not sure which one
