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 a bottle of water throughout the day. That afternoon, they 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 third week they run the bleachers but drink a gallon of water beforehand.

This question is incomplete; it is asking to identify the variables in the experiment such as Independant variable, dependant variable, Hypothesis, Control group, expiermental group, Constants etc

independant variable: Amount of water

Dependant variable: Endurance/Number of times each player can go up and down before catching breath

Hypothesis: IF the football players take an increased amount of water, THEN their endurance increases.

Control group: None in this experiment

Experimental group: The players that were given the water

Constants: Same time interval, Same bleachers

Explanation:

The hypothesis of an experiment is a testable explanation given to predict a solution to an observed problem or question. The hypothesis in this experiment, which can be tested to be proved/disproved is: IF the football players take an increased amount of water, THEN their endurance (number of times to run up and down) increases.

Independent variable is the variable that is manipulated or changed by the experimenter. The AMOUNT OF WATER is the independent variable in this case.

Dependent variable is the variable that the experimenter measures or the variable that responds to a change in the independent variable. The dependent variable in this case is the Endurance/Number of times each player can go up and down before catching breath.

The experimental group is the group that receives the experimental treatment. In this question, the players that received the water is the experimental group. On the other hand, the control group is the group that does not receive any treatment or independent variable, which there is none as far as this experiment is concerned.

Constant or controlled variable is the variable that an experimenter keeps unchanged or constant throughout the experiment in order not to influence the outcome. The constants in this experiment are Same time interval before next treatment, Same bleachers run

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

i dont know it at allnow im just getting points at this pint
