Explore the Internet and research one digestive system disease or disorder. Use the image search feature on a browser such as Google to find an image that shows a sign or symptom of the disease or disorder you have selected. Be sure that you can explain what the image is showing. Identify all anatomical structures in the image as appropriate. Discuss whether this disease or disorder is something that is more or less prevalent within a specific age group across the lifespan. Also, make a brief statement about how the homeostasis of the body can be impacted by this disease. What is happening in the digestive system that

Step 1: Read and review Chapter 5 and Chapter 6 in your textbook.

Step 2: Discuss the following:

· To what extent do you think that an individual’s gender impacts the development of their gross motor skills?

· Do you feel that gross motor development is more influenced by genetics or environmental factors?

· Based on research and your assigned readings, how might your explain the anticipated gross motor development to a family of fraternal male/female twins in a clinical setting?

· Do you feel that an individual’s cultural background can impact gross motor development within these ages for both boys or girls?  Explain why or why not?

Nutrition

/in /by

Last week you were introduced to nutrition and the components of a healthy diet. This week you are learning about digestion and carbohydrates. Digestion is the process by which our body breaks down the foods we eat to provide obtain its energy, essential nutrients and other chemicals that are critical for life. Understanding the digestive process will help you evaluate the myriad of nutrition claims we are confronted with every day.

Our body makes energy from the carbohydrate we eat and drink.  Glucose is our body’s preferred energy source, but fatty acids provide an alternative energy source when needed.  This forum will explore deeper several topics related to digestion and carbohydrate.

Your initial forum must be at least 250 words, posted by Tuesday11:55 pm EST, and contain at least one outside, reputable reference. You need to state your thesis and support it with at least one outside, reputable reference. Your textbook is not an outside reference. Remember, there is no right or wrong. Before you post your initial forum discussion, submit it in the assignment area so its originality will be checked by turnitin.com. I will take points off if you do not do this. Before you post your discussion, make sure your originality index (%) is less than 15. If it is greater than 15, rewrite your discussion, submit it again in the assignment area and check the %. Keep doing this until your % is less than 15. Only post your discussion when the % is less than 15.

Once you have posted your initial forum discussion, you must reply to at least two other learner’s post.  Each post must be a different topic.  So you will have your initial post from one topic, your first follow-up post from a different topic and your second follow-up post from one of the other topics.  Of course, you are more than welcome to respond to more than two learners. Your follow-up post must be posted by Sunday 11:55 pm EST.

If your last name starts with, then you will discuss…

First Letter of Last Name

Topic

A through F

Topic 1

G through L

Topic 2

M through R

Topic 3

S through Z

Topic 4

Topic 1:  Should a product be labeled as Genetically Modified (GM) if it contains an ingredient that has been genetically modified? Currently, the FDA requires a GM food to be labeled as such only if there is a substantial difference in nutrient content, the food contains an allergen that would not normally be present, or the food contains a toxicant beyond a certain limit. Do you think consumers should know if their food contains GM ingredients? What are some of the advantages and disadvantages of labeling foods as either containing GM ingredients or as “GM free”? How would you use this information?

Topic 2:  Your friend wants to know what is riskier: the bacteria present in food or the additives listed on the food label. How would you respond? On what information would you base your conclusion?

Topic 3: Mary is going to cleanse her gut.  She is thinking of using laxatives and enemas every other week.  What reasons would you give her to steer clear of the regime? What are some possible harmful effects?

Topic 4: Mike was recently diagnosed with type 2 diabetes.  He is feeling good and has not noticed any changes in his health.  Sam, his twin, has not been diagnosed with type 2 diabetes.  They both like the same activities and foods. Mike does not understand why he has diabetes, but his brother does not and why he has not had any noticeable symptoms. How would you explain this to him?

Your initial forum and follow-up forums will be graded based on the following rubric.

Note that my topic is Number 3

Create a fifteen to thirty (15-30) slide Prezi presentation in which you:

1.Create a section (five to ten [5-10] slides) in which you:

a.Compare and contrast three to five (3-5) diversity approaches, focusing on their application to a classroom environment.
b.Analyze key instances in which you have experienced each diversity approach in action in your own life, focusing on events that took place in a K-12 environment.
c.Provide between three to five (3-5) images that demonstrate diverse classrooms in each instance discussed in the question above.

2.Create a section (five to ten [5-10] slides) for multicultural approaches in which you:

a.Design a unit that relates to your grade level and area of instruction that focuses on the approach to multicultural education you have selected.
b.Choose resources that could be used to deliver this unit. Consider the use of any appropriate adaptive learning technologies as well as incorporating International Society for Technology in Education (ISTE) National Educational Technology Standards (NETS).
c.Recommend at least three (3) strategies that teachers can choose from to integrate multicultural techniques into their classrooms.

3.Create a section (five to ten [5-10] slides) for philosophies of multicultural education in which you:

a.Create a diagram that demonstrates your personal philosophy of multicultural education and its major applications to a K-12 curriculum.
b.Determine which evaluation criteria you would use to examine the effectiveness of a multicultural curriculum.

Your assignment must follow these formatting requirements:

  • Follow APA for formatting guidelines. Check with your professor for any additional instructions.
  • Include a cover slide containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover slide and the reference page are not included in the required assignment page length.

Directions for submitting your presentation:

  • Submit your presentation to the area designated by your professor.
  • Review at least two (2) other classmates’ presentations and post a response indicating what you learned by identifying two (2) specific points that were made in the presentation.

The specific course learning outcomes associated with this assignment are:

  • Formulate a personal and professional philosophy with respect to multicultural education.
  • Examine and analyze various diversity approaches and apply them to the learning environment.
  • Identify instructional strategies that are applicable to the K-12 diverse learning environment.
