Question

Identify the independent variable and the dependent variable in your penny
experiment?

Answer 1

In an experiment, the independent variable is manipulated by the researcher, while the dependent variable is the observed result that may change due to the manipulation of the independent variable.

Step-by-step explanation:

Understanding Independent and Dependent Variables in Experiments

In an experiment, the independent variable is the factor that the researcher changes or manipulates, while the dependent variable is the factor that is observed or measured to see if it is affected by changes in the independent variable. For instance, when a scientist is testing if bacteria grow faster on gel A or gel B, gel type (A or B) is the independent variable because it is what is being changed. The number of bacteria that grow, which is observed after 24 hours, is the dependent variable as it is what the scientist is measuring and depends on which gel is used.

Designing an experiment requires careful consideration of these variables to ensure that any observed effects can be attributed to changes in the independent variable, not to other factors. The control of other potential variables is critical to establish a cause-and-effect relationship.

Answer 2

Independent Variable = The thing you change

Dependent Variable = The thing you measure

Step-by-step explanation:

An independent variable is the thing that you are changing in your experiment to be able to get different results. For example, if a question says "What will happen to a cup of tea when you change the temperature of the water added to it?"... then the independent variable will be the temperature of the water.

A dependent variable is the thing that you are measuring. For example, if you are studying the amount of light absorbed from different surfaces, then the dependent variable is the unit of light absorbed, which would be measured in Au (Absorbance unit).

You can now take this knowledge and apply it to your question.
