Scientific Method Assignment 2: Design an Experiment Instructions

You are presented with a nutritional supplement. The label claims that the supplement, ginseng, has a variety of benefits, including it reduces inflammation, enhances memory, boosts the immune system, and lowers blood sugar.

For one of these claims, propose a hypothesis and a specific experiment to test your hypothesis. Include the details of your experimental design. Look at the rubric to see what should be addressed in your short paper.

Important Information

You will not actually be performing this experiment! Simply write a proposal outlining how you would test this claim. Write in active voice (“I will perform…” instead of “Experiments will be performed…”). Make sure that you propose a reasonable number of subjects for each group, and think about variables that could confound your results. Refer to the rubric for specific grading criteria.

How to Submit Your Assignment

Follow the prompt above and design your experiment in a one-page, typed paper.
