Variables: What will be staying constant versus changing in this experiment? in the Homeostasis lab acivity

Answer 1

In the Homeostasis lab activity, the variables that will be staying constant or changing are:

1. Independent variable: The factor that is intentionally manipulated or changed by the experimenter. In the Homeostasis lab activity, this could be the external temperature, the amount of physical activity, or the intake of fluids.

2. Dependent variable: The factor that is measured or observed to determine the effect of the independent variable. In the Homeostasis lab activity, this could be the body temperature, heart rate, blood pressure, or levels of electrolytes.

3. Control variables: These are the variables that are kept constant throughout the experiment to ensure that only the independent variable affects the dependent variable. In the Homeostasis lab activity, this could be factors like the initial body temperature, the amount of rest or sleep before the experiment, the age or gender of the participants, and any medications or illnesses they may have.

4. Time: The duration of the experiment will also stay constant or change as per the experimental design. Certain measurements might be taken at specific time intervals to observe any changes over time.

It is important to control for these variables in order to accurately assess the impact of the independent variable on the dependent variable and to ensure the validity of the experiment's results.
