Solution-Experiment a high school student | Homework Helpers

You live in a rural are. Your local radio station reports the results of an experiment a high school student conducted to test the effects of a healthy diet on the saturated fat content of cow’s milk. The student’s father bought 6 cows from two different sellers. Cows from seller 1 were fed the student’s special mixed-grass diet; the other cows from seller 2 were fed the usual animal feed. The student discovered that milk from the cows had lower saturated fat than then cows fed the usual feed. The radio station report created a lot of attention and coverage in other media beyond the local radio station. The student thought he might look into a financial sponsor to promote and even patent his special mixed-grass diet. Based on this limited information and using the scientific method:

I. What problems do you see with the student’s study?

II. Help the student develop a better question followed by a hypothesis. Then …

III. Design a brief experiment to test your hypothesis (make sure to indicate a control) and describe (in brief) predicted results.

(The reading for this week will also help you in this exercise).
