A Scientist wonders if the amount of Vitamin C that he feeds to rats will have any affect on the rat's mass. He measured both the mass of the rats and the amount of vitamin C in grams. I need to find the Independent variable, Dependent variable and the controlled variable?

I think u should ask ms sue

To identify the independent variable, dependent variable, and controlled variables in this study, we need to understand their definitions and roles in an experiment:

1. Independent variable: This is the variable that the scientist purposely manipulates or changes in order to see its effect on the dependent variable. In this case, the independent variable is the amount of Vitamin C that is fed to the rats. The scientist will vary the dosage of Vitamin C and observe its impact on the rats' mass.

2. Dependent variable: This is the variable that the scientist measures or observes to determine the effect of the independent variable. In this study, the dependent variable is the rats' mass. The scientist is interested in discovering whether the amount of Vitamin C they receive has any influence on their weight.

3. Controlled variables: These are the variables that the scientist keeps constant or consistent throughout the experiment. By controlling these variables, the scientist ensures that any observed changes in the dependent variable are caused by the independent variable and not by other factors. In this case, examples of controlled variables may include the rats' age, breed, diet (except the amount of Vitamin C), housing conditions, etc. These factors are kept constant, so they do not confound the relationship between the independent and dependent variables.

In summary, the independent variable is the amount of Vitamin C given to the rats, the dependent variable is the rats' mass, and the controlled variables are other factors that the scientist keeps constant to ensure the experiment's validity.
