If it was not identified then you would not know what to change or what stays the same.
the experiment result would be confusing
. 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
there is only one manipulated varable in an experiment otherwise it would not be a controlled experiment
Well, when something changes, you would not know which variable caused the change in the experiment.
a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
In Reid's experiment, the primary variables include the independent variable, which is the factor manipulated by the researcher, and the dependent variable, which is the outcome measured to assess the effect of the manipulation. Additionally, control variables may be employed to ensure that other factors remain constant throughout the experiment, allowing for a clearer interpretation of the results. Specific details about these variables would depend on the context and focus of Reid's experiment.
Observation.
For instance, in an experiment on plants, some plants may be subjected to variables - different fertilisers, soil, temperature, daylight, diseases, etc. While other plants would be kept separate as a control. The control plants would not be subjected to any variables or experiments. The control plants would be used to compare the growth and the effects on the plants that were subjected to the variables.
The dependent variables in a copper wire resistance experiment would typically be the resistance of the copper wire being measured. This would vary based on factors like the length and thickness of the wire, as well as the temperature.
The experiment consisted of copper pennies, 5 small beakers, and dropper bottles of: dish soap, water, ethanol, and baby oil. We had to drop these liquids onto pennies and see which could hold the most. So, what would be the manipulated, responding, and controlled variables in this experiment?
An experiment must have a control to show what would happen if no factors were changed.
