The modified choke could be the control
is the experiment that you are testing
i believe it is how long an experiment is going to take. for example, the testing range of an experiment with plants may take around a few weeks to months.
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.
A control is anything that stays the same during the experiment. For example say you were testing the affects of different liquids on plants; some controls would be the temperature you keep the plants, the amount of light you give them, etc.
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

A control is a testing kit that can help the variable.
a control is testing the kit to help the variable
The control in a science experiment is the same thing as a constant. It is something that you keep the same the entire experiment. For example if you were testing how various locations affect temperature your constants would be the thermometer you used and the time for measuring the temperature. If you don't have a constant than your experiment results won't be accurate.

Control Experiment
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.
A control in a science fair project would usually be a separate running of the experiment where you don't change anything. Example: If you are testing the effect that music has on plant growth, you would grow a plant with no music.

Hypothesis testing. Being willing to conduct an experiment which could prove one's ideas wrong.
