Well, it is that time – yes, time for that talk. For this activity, you will develop a PowerPoint presentation about human reproduction. You are to pretend that the presentation is what you will use to give your son or daughter “the talk” about human reproduction.

Objectives

Identify the major structures and functions of the endocrine, skeletal, muscular, reproductive, and nervous systems.
Evaluate various risk factors for diseases within body systems.
Describe differences between male and female body structure and function.
Explain sexual reproduction and development in humans.
Differentiate between diseased states and homeostasis.
Distinguish between the functions of the various glands of the body.

Materials

Computer with internet access

Directions

Make sure you use correct terminology, and include the following in your presentation:

Overall purpose of the reproductive systems
Information about the male and female systems
At least two visual aids illustrating the two systems
Structure and function of the organs involved
Practicing “safe sex” and preventing pregnancy and STDs
Use bulleted information on slides (five lines or less)
Include detail in the speaker’s notes
Include a separate title slide and a separate reference slide
Use appropriate font and backgrounds
Include at least six slides (not counting your title slide or reference slide)

Part I: Media Relevancy

Read each statement.

Write a 100-word summary explaining how the chosen media piece supports the statement. Include reference citations.

1. Find a media piece—article, video, presentation, song, or other—that recognizes the fundamental concepts of chemistry in biology. Include the link or reference citation for the piece and describe how it helped you better understand how fundamental concepts of chemistry affect biology.

2. Find a media piece—article, video, presentation, song, or other—that describes the energy metabolism of cells. Include the link or reference citation for the piece and describe how it helped you better understand the energy metabolism of cells.

3. Find a media piece—article, video, presentation, song, or other—that compares the structures and functions of different cell types. Include the link or reference citation for the piece and describe how it helped you better compare structures and functions of different cell types.

4. Find a media piece—article, video, presentation, song, or other—related to the scientific method, creating hypotheses, or designing experiments. Include the link or reference citation for the piece and describe how it helped you better understand how the scientific method is used to create hypotheses and experiments.

Part II: Applying Science to Everyday Life

Recently, Earl attended a picnic at his daughter’s school. The picnic was a potluck, and the food was served outdoors. Contributions included hamburgers, hot dogs, baked beans, potato chips, potato salad, coleslaw, apple pie, and vanilla ice cream. Within 24 hours of the picnic, several attendees developed symptoms of food poisoning. Of the 50 people who attended the picnic, only 30 people became ill. Every person at the picnic ate something, but not every person had an opportunity to sample each item. Earl noticed that the potato salad he started to eat was warm. He also noticed that his hamburger was somewhat pink in the middle and not fully cooked. Earl wonders if eating the hamburgers or the potato salad could be responsible for making some attendees ill. Earl has begun to apply the scientific method to this common problem. Complete each of the following tasks in 200 to 300 words.

1. How would the scientific method help Earl create an experiment to determine which food sources made people sick?

2. Describe the steps of the scientific method Earl utilized.

3. Describe the remaining steps Earl will use if he decides to use the scientific method to determine what made the people sick.

LAB NOTEBOOK

Proceed through the entire lab simulation protocol. Be sure to read the captions below the pictures (left side) and the information in the lab notebook (right side). Be sure to “start over” to begin the lab. You CANNOT skip any steps. Answer the following questions as you proceed.

1. What is systemic lupus erythematosus (SLE)?

2. From Figure 1 (click on it), what are the four steps of an ELISA protocol?

a. ___________________________________________________________

b. ___________________________________________________________

c. ___________________________________________________________

d. ___________________________________________________________

3. In step 1, you centrifuge the samples. What does a centrifuge do?

4. What are you preparing in step 2? Why are there three different solutions?

5. In steps 3 and 4, you prepare an ELISA plate. What has the ELISA plate been pretreated with? Why?

a. What is the positive control? (Step 4)

b. What is a primary antibody? Please define.

c. What is the negative control? (Step 4)

d. Why is it necessary to have a positive and a negative control? (Step 4)

6. Why incubate the plate in step 5?

7. Next, in step 6, the plate is washed. Why wash the plate?

8. In step 7, a secondary antibody is added. What is a secondary antibody? Please define.
