Question

Use the scientfic method to design an experiment testing the hypothesis that cows produce a different amount of milk when fed freshly cut grass than when fed commercial feed. Identify dependent, independent, and controlled variables.

Answer 1

Answer:

The experimental protocol is:

Two treatments are carried out, one of them with 10 cows that feed on freshly cut grass and another treatment with 10 cows that only feed on commercial food, it is important that the cows are dairy cows.

After 5 days of feeding them, for 10 days the cows will be milked by measuring the amount of milk with a container that measures liters and is equal.

Subsequently, a graphic analysis will be made with Liters of milk as a dependent variable and treatment 1 and time as a dependent variable in each of the treatments.In this case the amount of grass and the type of grass are controlled variables.
