Topic: What Should You Eat?

You probably want to live a long and healthy life on this earth. What are you willing to do to make that possible? Here is an assignment that can improve the quality of what you eat, and hence, the quality of your life. Let's develop the rudiments of a maintenance diet for you—a desirable, workable, realistic, non-faddish maintenance diet—one you follow permanently. You have several reference sources:

- the Bible’s many prescriptive texts regarding nutrition (ignore “descriptive” texts)

- your textbook’s chapter on biomolecules; how they are built and used

- the course Presentation entitled “Biomolecules and Nutrition”

- trustworthy sources such as

- USDA MyPlate:  https://www.choosemyplate.gov/MyPlate-Daily-Checklist

- the Mayo Clinic website.  http://www.mayoclinic.org/healthy-lifestyle

- Very Well website (David Katz’ site):  https://www.verywell.com/

- Web MD:  http://www.webmd.com/diet/default.ht

The foods you select will contain the same classes of biomolecules that you read about in your textbook: carbohydrates, lipids, proteins, nucleic acids, vitamins, and minerals.  Use the following procedure to build your diet.

For your Thread:

1.  Click on the link below.  This will give you a Word document “work table” to add your foods to.  You may wish to print a copy for research purposes.

What Should I Eat - Work Table.docx

2.  Go to the “My Plate Check List Calculator https://www.choosemyplate.gov/MyPlate-Daily-Checklist-input   Enter your data to determine how many calories your daily diet should contain. Record this number in your work table.

3.  Now go to the USDA MyPlate web site: https://www.choosemyplate.gov/MyPlate-Daily-Checklist  In the Table, about the middle of the page click on the box representing your caloric needs.  Some serving amount data will pop up allocated into 5 food groups.

4. Record the suggested serving amounts in your work table to give quantitative values to the categories you will build your diet around.

“What Should I Eat?” – Work Table:

 

 

 

 

 

Total Calories:	/per day
Food Group:	Biomolecules in this Group in Order of Relative Biomass*	Serving Amount:	My Food Choices:
10 Fruits	Carbs, Proteins, Oils		My first food, my second food, my third food, my fourth food, etc.
12 Vegetables	Carbs, Proteins, Oils
12 Grains	Carbs, Proteins, Oils
9 Proteins	Proteins, Fats, Oils
7 Dairy Items	Depends on the Food

 

5.  Start to choose foods using the guideline comments given on the webpage.  Use other web pages listed above to get commentary on foods you think (!) are healthy for you.  Here are two useful ones to give you ideas:

https://www.verywell.com/macronutrients-made-simple-4128991 , https://www.verywell.com/the-basics-of-a-healthy-balanced-diet-2506675

6.  Delete the sample foods listed in the “Fruits” category.  They are there to show you the format for your own additions.  List specific foods that you would eat for each group according the numbers indicated in the first column. The second column of the table will help you with your category accuracy.  Do not reuse any food under a second category. You will thus select 50 foods for your diet—not a huge variety, but it's a start!  “Leafy greens” or “seafood” are food categories, not  specific foods.

7.  “Mouse over the upper left-hand corner of the table to find the tiny navigation box and click on it.  This highlights (“selects”) the whole table.  Copy it to your computer’s “clipboard”.  You can now paste this table into the “Message Box” of your open “Thread” in the discussion board.  Along with your table, you may submit up to two prescriptive Bible passages that you feel most constrain your dietary thinking.

Hints:

•    Your goal is always to improve your own list. Please include about 70 words for your diet (50 foods, some hyphenated as needed) with space left over for two Bible verses for a total of 120 words.  That’s your limit!

•    Foods differ in their density of a wide variety of nutrients as compared to just the calories they give you.

•    What is in the food item you've selected? Check out:  http://ndb.nal.usda.gov/  to find out.

•    Suppose Mayo Clinic wisdom and Biblical wisdom seem to conflict.  Which source will you defer to and why?

Topic: Birth Control

You and your classmates differ widely in your familiarity with this topic: 1) You may be unmarried and have not thought much about it yet. 2) You may be married with a family and have used birth control at some point. 3) You may have been badly disappointed by some method of birth control. 4) You may view birth control use as unscriptural. Can you see the high value in doing some research on this as a group and then—lovingly, humbly, and modestly—sharing your conclusions with each other? This could be a tremendously valuable discussion, especially for the younger members of the course. This is an opportunity for ministry.

Preparing for your discussion:

Research using 4 reference sources:

Scriptural statements about life's sanctity and God's authority over creation of life

The section on "Control of Birth" in your textbook's chapter on human reproduction

The course presentation entitled "Birth Control Issues"

Trusted websites considering birth control issues/methods

As you use these sites, search for numbers, frequencies, and quantitative comparisons. Numbers in your threads and replies mold you into a scientist and will improve your scores on this board.

Preparing for your thread:

Evaluate these 6 general categories of birth control for your classmates:

Pills/patches/rings (estrogen and progestin based)

Sympto-thermal and condom/diaphragm

Intrauterine devices (such as ParaGard, Mirena)

Surgical – vasectomy (male sterilization)

Surgical – tubal ligation (female sterilization)

Male withdrawal during sexual relations

Compare each of these 6 categories against the following 4 criteria:

Protects the rare new life formed while the method is in use

Protects maternal (paternal?) health

Is reversible

Is effective

It is assumed that these 4 criteria are not equally important. Ignore the following criteria: value in preventing STDs, cost, and ease of use.

Choose the category of birth control that you discover to represent the best balance of these 4 criteria. Assume that you are selecting this birth control for a young, married woman with no unusual sexual health issues. Avoid exceptional personal experiences by generalizing from the 4 reference sources above.

Writing your thread:

Either: Represent your choice using 3 numbered sentences: Sentence 1 (very short) states the category you have chosen. Sentence 2 (using many phrases) explains the principle virtues of your category based on the above 4 criteria. Sentence 3 lists the single greatest limitation of your category.

Or: If you categorically will/would not use any birth control method, use your sentences in the following way: Sentence 1 states your position and gives a biblical passage (reference only) that urges you toward your position. Sentence 2 explains which category of birth control least offends you and why. Sentence 3 explains which category of birth control most troubles you and why.

Topic: Intelligent Design

You and your classmates are ordinary citizens interested in science education. You have been assembled into an advisory group. The Virginia State Education Commission is drafting a policy that will affect all school boards in the state. You are being protected in a secluded hotel from ACLU lawyers and right-wing demonstration groups. Here is your question: is intelligent design theory scientific? The Virginia State Education Commission is paying you thousands of dollars for a simple yes or no answer to this question. Such an answer may be unrealistic, but court battles will follow. You need to get as close to a yes or no answer as possible.

As a group, you have 3 reference sources:

Your textbook's 2 chapters on origins and the scientific method

The course presentation entitled "Origins, ID, and the Public School Classroom"

Two expensive expert witnesses: Michael Behe, a Lehigh University biochemist, and Eugenia Scott of the National Center for Science Education (your two expert witnesses come to you from presentations in the Reading & Study folder of Module/Week 7)

For your thread:

As panelists, first do your homework, then make a decision: based on how the scientific method works, is intelligent design theory scientific? Can you use it to do science?

The title must begin with the word "yes" or "no." Using 3 concise, numbered sentences, argue your answer.

INDIVIDUAL ASSIGNMENT 1

Many of you have spent hours thinking about why human beings exist. Most of you are very satisfied with the biblical answers to that question. However, entertain this question for a few moments: Why do all the life forms other than man exist? Why are they all here?

Evaluate and analyze the arguments in the presentation “Biblical Basis of Life’s Significance,” found in the Reading & Study folder of Module/Week 1. Construct a single sentence of 40 words or less. Include within it 4 carefully crafted and concise phrases that argue that life forms other than man are significant—they were worth creating. Start your sentence with the words:

“Life forms are significant because...”

Then add the 4 phrases, separating each with a comma. Order your phrases such that the most significant comes first and the least significant comes last.

Your assignment:

1.          Write out your masterful sentence.

2.          The sentence must be submitted through the appropriate assignment link and must not be submitted as an attached document, but entered into the text box provided.

INDIVIDUAL ASSIGNMENT 2

Attention deficit disorder (ADD) is a syndrome in which a person has difficulty focusing sustained attention on a task for a significant amount of time. In some cases this is accompanied by hyperactivity as well. It is currently being diagnosed at an all-time high. Between 1989 and 1996, youth visits for ADD increased 90%, from 1.9% of total physician visits to 3.6%.

Now, a psychiatrist named Dr. Edward Hallowell is making a new distinction. He has described a similar set of characteristics in a large number of patients that he terms Attention Deficit Trait (ADT). It looks a lot like ADD in its day-to-day manifestation, but unlike ADD, ADT symptoms lessen when the sufferer goes on vacation or into a decreased sensory input setting for an extended time period (on the order of days or weeks). In such a long-term placid situation, the ADD sufferer’s problems continue unabated.

Imagine that you have the general set of symptoms described above. But which of the two syndromes are causing your symptoms: the disorder (ADD) or the trait (ADT)? Approach your problem using scientific methodology—developing a question, a hypothesis, an experiment, and a control for the experiment.

The initial question and the experiment that will be performed on you are provided. Your job is to state the hypothesis and to design the most important and most basic control for this experiment.

Your Question: What’s my problem? Is it ADD or ADT?

1.          Your Hypothesis: State your hypothesis based directly on the above question.

Your Experiment: Keeping your same diet, sleep habits, and basic activity level, you will be sent on a two-week vacation to the Bahama Islands. You will be given only a beach to walk on and your favorite friend to talk to, following which you will be asked to read and memorize 10 sequential definitions from a standard dictionary in 30 minutes.

2.          Your Control for this Experiment: You get a numerical result for the number of definitions you memorized. What does that number mean? Nothing—unless you have a control for your experiment. What is the most obvious control for this experiment?

Major Hint: The study guide for Quiz 1 indicates where this topic is covered in your text. The two figures in that section give you valuable examples. Remember, the initial question and experiment are provided here. Be careful to provide what the assignment is asking for.

Your assignment:

1)          Write out a testable hypothesis in a brief sentence. Derive it from the question asked above. (Be certain that the experiment addresses it!)

2)          In a second sentence, describe a basic, critical control situation (additional experiment?) that will give validity to the experiment described above.

Number your sentences with “1” and “2” and do not use paragraph form. The sentences must not be submitted as an attached document, but entered into the text box provided.

Submit this assignment by 11:59 p.m. (ET) on Monday of Module/Week 1.

INDIVIDUAL ASSIGNMENT 3

The global community is plagued by increasing incidence of leukemia; non-Hodgkin lymphoma; lung, colorectal, breast, pancreatic, prostate, liver, ovarian, and esophageal cancers. Other types of cancer exist but are less frequent. What is the scientific community doing to attempt to eliminate the most common forms of cancer that are ravaging society?

1.          Read the course textbook’s chapter on cell division, specifically the last section on how cells become cancerous. This is context for completing Individual Assignment 3.

2.          Watch the Presentation in Module/Week 4 entitled “Ways to Fight Cancer.” Notice that the presentation outlines essentially 3 approaches to fighting cancer: a) reduction of cancer risks, b) correction of cancer genes, and c) destruction of cancerous tissue.

3.          Open the “10 Discoveries in the War on Cancer” document in the Assignment Instructions folder. Scan the discoveries briefly. Then, open the assignment submission link in Module/Week 9. In the text box, number from 1 to 10 for the 10 discoveries.

4.          Reflect carefully on discovery 1. Would this discovery be more useful for a) reducing cancer risks, b) correcting/restoring cancer cells to normal, or c) destroying cancerous tissue? After number 1 in your list, place in parentheses the letter representing the approach to fighting cancer that will best be served by this new discovery. (More than 1 approach may be served, but which is most likely to be helped most significantly?)

5.          Repeat this analysis for each of the remaining 9 discoveries. Return to the “Ways to Fight Cancer” presentation as needed for additional perspective. When finished, your entire text box must be simple: a numbered (1–10) list of letters (a), (b) or (c). The assignment is now complete.

6.          Each correct association up to 8 correct answers is granted 7 points. If you get 9 or 10 out of 10, you get a perfect score (60 pts.) on the assignment.

Submit this assignment by 11:59 p.m. (ET) on Monday of Module/Week 4.
