Question

name: class: date: essay lets say your cafeteria is embracing the new nationwide health - kick. on wednesdays, they serve \surprise lasagna\ which is low - fat and low - sodium. however, this wednesday, you find out (from an insider) that the head cook will be using a new recipe on the unsuspecting freshmen. the cooks plan to prepare the two kinds of lasagna side by side. they have made the decision to try the new recipe on the unsuspecting freshmen. they know that the freshmen will notice the new taste. their responses may vary, but you may expect to see freshmen making faces as they eat their unfinished meals or making strange facial expressions as they eat the lasagna. the cooks will compare the freshmens reactions to their reactions to the regular lasagna. once the experiment concludes, the cooks can analyze the results and draw conclusions. their analysis may also lead to other questions about food preparation. questions: 48. what is the independent variable in this passage? 49. what is the dependent variable in this passage? 50. what is the control group in the passage? bonus(10pts): write in the statements from above in order of the scientific method and tell why were the freshmen chosen to be the test subjects? (all must be correct in order to receive points) 1. 2. 3. 4. 5. 6. 7. why freshmen?

Explanation:

Step1: Identify independent variable

The variable that is deliberately changed is the new lasagna recipe.

Step2: Identify dependent variable

The variable that is measured as a result is the freshmen's reactions (expressions as they eat, etc.).

Step3: Identify control group

The control group is the sophomores who get the old - recipe lasagna.

Step4: Order of scientific method

1. Observation: Cafeteria is reacting to health - kick.
2. Question: How will freshmen react to new lasagna?
3. Hypothesis: Freshmen will notice and react to new recipe.
4. Experiment: Serve new recipe to freshmen, old to sophomores.
5. Data collection: Observe freshmen's reactions.
6. Analysis: Analyze freshmen's reactions.
7. Conclusion: Draw conclusion about new recipe's success.

Step5: Reason for freshmen as test subjects

Freshmen are likely to be new to the cafeteria and less accustomed to the usual food, so their reactions may be more pronounced and less influenced by long - term preferences compared to upper - class students.

Answer:

1. The new lasagna recipe.
2. The freshmen's reactions (expressions as they eat, making strange facial expressions, etc.).
3. The sophomores who get the old - recipe lasagna.

Bonus - Order of scientific method:

1. Observation
2. Question
3. Hypothesis
4. Experiment
5. Data collection
6. Analysis
7. Conclusion

Why freshmen?: They are new and less influenced by long - term cafeteria food preferences, so reactions may be more pronounced.
