Coach Damien notices that some of his football players drink more water than others before Friday night games. He is interested

if the amount of water the students drink affects their endurance. One week before practice he has each student drink an bottle of water throughout the day. That afternoon, the run the bleachers and he records how many times each player can go up and back before stopping to catch their breath. The next week they do the same thing but drink 2 bottles of water beforehand. The this week they run the bleachers but drink a gallon of water beforehand.

The independent variable identifies the amount of water intake among the football players.

The endurance of the players, assessed by counting how many times they ascend and descend the bleachers before needing to rest, serves as the dependent variable.

The coach hypothesized that greater water consumption would lead to enhanced endurance in the players.

This experiment lacks a control group, although it would consist of players who did not consume water prior to practice.

The experimental group comprises players who did drink water before their practice sessions.

Constants throughout the experiment include the definition of endurance (the method of measuring it), the volume of water each player consumes weekly, and the players involved in the study.

The absence of a control group raises concerns about the reliability of the results obtained from this experiment.

Answer:

An experiment in science is structured to evaluate a hypothesis.

This setup includes three kinds of variables: the independent variable, which can be adjusted; the dependent variable that needs to be measured; and a constant, which remains unchanged throughout the duration of the experiment.

Scientific experiments can be divided into two groups: the experimental group, where the dependent variable undergoes testing, and the control group, where the dependent variable is absent.

Thus, addressing the provided question:

1. Independent variable- the varying amount of water administered during the experiment.

2. Dependent variable- the assessed endurance levels.

3. Hypothesis- Increasing water intake leads to enhanced endurance in athletes.

4. Control group- There was no control group involved in this experiment.

5. Experimental group- those participants who consumed water prior to their practice sessions.

6. Constant- the consistent number of players and their weekly water consumption.

7. The issue lies in the absence of a reference group or control group which would supply comparative data.
