1. You need to ask a question (i. e., develop a hypothesis) about the cause or treatment of cancer.

2: Describe what you would like to measure (i.e., carry out an experiment) that will answer your question (test your hypothesis).

The experiment doesn't need to be carried out, just explain why you think the measurements you chose will help you answer your question

DESIGNING YOUR OWN NUTRITION EXPERIMENT Just like other scientific disciplines, factual nutrition information is based on experimental research that has been replicated many times by different scientists. Below, you will construct a realistic intervention study, using human volunteers, to answer a nutrition related question of your choice. Be sure to include as much detail as possible.

1. Your Question to be tested:

2. State your hypothesis concerning your above listed question

3. In testing your hypothesis, who will you recruit for your experiment? (Include things like age, gender, health status and the total number of subjects)

4. Briefly explain your experimental protocol. (Give as much detail about what you will do with your experimental subjects)

5. What variables will you test for? (What things are you going to measure?)

6. How do you plan to limit the subject bias? (How will you prevent your volunteers from reporting effects simply because they know they are participating in your experiment?)

7. What limitations do you foresee in carrying out this experiment?

Scientific Method Exercise
Identify a situation in which you applied the scientific approach to solving a problem. Share your thinking! The problem you choose to write about can be very simple, such as: my flashlight won't work, or my car won't start, or I baked muffins and they were flat ( didn't rise properly) , or the toilet won't flush properly, or better yet, think of your own. These probably don't sound like "science" problems, but it is most likely that you would use the scientific method to solve them, without even realizing it. Avoid using people problems and child or pet behavior issues as your "problem." Follow these steps to create your first writing assignment:

1. Describe the situation and your observation,
2. Describe your hypothesis to explain the observation.
3. Describe your further observations or experiments to test the hypothesis. Be sure your hypothesis is one that can be tested. Consider what you might use for "controls".
4. Was the hypothesis correct? If not, can you find a better one? Or do you need a better experiment? If so, what would it be?

The assignment should be formatted as follows: Be sure to include the labels, so it is clear that you recognize and identify each step in the process.
Problem: (briefly describe your problem here)
Question: (This may be a "how" or "why" question that you will formulate a tentative answer to. Your tentative answer is your hypothesis.)
Hypothesis: (State the answer to your question above. This is your "best guess" regarding the answer to the question.)
Prediction: (This describes your experiment very briefly and states the outcome you expect that would support your hypothesis)
Experiment: (Describe how you tested your hypothesis)
Results: (Describe what happened, and whether the results supported or failed to support your hypothesis)

I need help with Genetics question.

I would appreciate if detailed description is included.

The e4 allele of apolioprotein (APOE) increases the probability of developing Alzheimer disease (AD). How e4 does this is not known. You believe the e4 allele changes the structure of the APOE gene product so that it prevents the repair of small brain injuries, and that AD results from the accumulation of unrepaired small brain injuries, injuries individuals with normal APOE alleles repair. You want to do a study of the US population to test your hypothesis that AD results from unrepaired brain injury.

a. Briefly describe the study you want to do, and explain how this study will test your hypothesis.

b. Predict what results you would find if the hypothesis is correct.

c. Explain to the research funding board why you think these results would be convincing evidence that your e4 hypothesis is correct.
