Explanation: 

Detailed explanation-1: -These factors that change in a scientific experiment are variables. A properly designed experiment usually has three kinds of variables: independent, dependent, and controlled.

Detailed explanation-2: -What is a Conclusion? A conclusion is a statement based on experimental measurements and observations. It includes a summary of the results, whether or not the hypothesis was supported, the significance of the study, and future research.

Detailed explanation-3: -In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.

Detailed explanation-4: -A controlled experiment requires at least two variables: a manipulated variable and a response variable.
