Scientific Method Review
For the problem that follows you need to write out the steps of the scientific method as they apply to this problem and design an experiment to test your hypothesis. For your experiment you will need to identify the variables including the experimental variable, how you’ll keep the other variables constant (not changing) and the method of exactly how to complete the experiment, step by step. Your explanation will end at the point of gathering data, you won’t have any to gather and I don’t want you to make data up. (You can create situations for the purposes of this experiment on this worksheet that you might not be able to do at school for real). Use OCI as your possible test subjects.
The situation is that you need to find out which school lunch students like the most to least of the following lunches: Hamburgers, fries, apple slices and milk : Cheese pizza, salad, fresh fruit cup and milk: Ham sandwich, chips, grapes and milk: Peanut Butter and jelly sandwich, watermelon slice, pretzels, and milk.
