Giving ∆ Mandatory or Choice?

In the United States, there is a law called the Uniform Anatomical Gift Act, which gives people the opportunity and choice to donate their organs after they die. Contrast this with a law in France that decrees that organs and tissues can be used from a dead person UNLESS the person has objected in writing. The French law make a continuous supply of organs available for transplants, which will save many lives by reducing the wait time for organs. Do you think a government should decide the fate of your body at death? Take a position and defend your answer.

Scoring Guide:

3 The response is an excellent answer to the question. It is correct, complete, appropriate and contains elaboration, extension, and/or evidence of higher order thinking and relevant prior knowledge. There is no evidence of misconceptions. Minor errors do not necessarily lower the score.

2 The response is a proficient answer to the question. It is generally correct, complete, and appropriate although minor inaccuracies are present. There may be limited evidence of elaboration, extension, higher-order thinking, and relevant prior knowledge or there may be significant evidence of these traits, but other flaws such as inaccuracies, omissions, inappropriateness, are evident.

1 The response is a marginal answer to the question. While it may contain some of the elements of a proficient response, it is inaccurate, incomplete or inappropriate. There is little, if any, evidence of elaboration, extension, higher-order thinking or relevant prior knowledge. There may be evidence of significant misconception.

0 The response, although on topic, is an unsatisfactory answer to the question. It fails to address the question, or it may address the question in a very limited way. There is not evidence of elaboration, extension, higher-order thinking, or relevant prior knowledge. There is evidence of serious misconception.

Through the Heart

Instructions to the Teacher

After learning about the heart and how it pumps blood, students will show the path of blood flowing through the heart by threading a string through a dissected heart.

Materials

á One cow, sheep or pig heart for each group of students (can be obtained from a butcher or biological supply company). The heart will need to be cut in half (either by the teacher or by the students during a previous dissection lab) so that all 4 chambers and major vessels are visible and intact. Students will need to thread the string through the vessels, through the valves and chambers of the heart and out again through vessels. If the heart is cut open and lying in the dissection tray, the string can lay on top of open structures such as the ventricles and atria.

á yarn or twine

á dissecting tray

á dissecting equipment

á masking tape

á colored pencils

á "Through the Heart" test sheet

Instructions

1. Pass out test sheet "Through the Heart"

2. Have students collect materials and begin. You may wish to read the introduction and instructions with the students.

3. When students finish threading string through the heart, score and sign off that part of the test. You may need to remind them to finish the other parts of the test before cleaning up the lab equipment.

Scoring Guide

#2-3 String sequence through the heart:

(arrows should indicate direction of blood flow)

ÒFROM BODY---->Ó label, vena cava, right

atrium, valve, right ventricle, valve, pulmonary artery, ÒTO LUNGS ---->Ó label,

ÒFROM LUNGS ---->Ó label, pulmonary vein, left atrium, valve, left ventricle, valve, aorta, ÒTO BODY ---->Ó label.

2-3. Correct labels 8 points (2 points each)

String through correct 13 points (1 point each)

structures in correct order

4a. Arrows should follow the path of blood 7 points (approx. 7 arrows)

4b. Labels correct 4 points

4c. Red and blue correspond to oxygenated 6 points (approx 6 areas to color)

and deoxygenated blood in the heart and arteries

5a. Ventricle walls are thicker and more muscular than 2 points

atrial walls.

5b. Ventricles are more muscular because they need 2 points

the strength to pump blood to the different parts

of the body. Atria only need to pump blood into

the ventricles.

6a. Artery walls are thick, muscular and elastic. Vein 2 points

walls are thin and not as elastic.

6b. Thick, muscular artery walls expand and contract 2 points

to maintain blood pressure. They are also strong

to withstand the pressure.

7. They prevent the back flow of blood as different 2 points

parts of the heart contract and relax

8. When ventricles contract, blood moves 2 points

backward through the open valve. This results in a

less efficient heart. (A minor leak in a valve of the heart

is called a heart murmur)

TOTAL 50 Points

Through the Heart

Name______________________________________________________ Period_______ Date_______

Introduction

You have learned structures of the heart and how it pumps blood to various parts of the body. Now you will demonstrate your knowledge by threading a string through the heart to show the path of blood flow through the heart.

Materials

¥ heart (cut open) ¥ small beaker of water ¥ colored pencils

¥ string or twine ¥ dropper

¥ dissecting probe ¥ scalpel

¥ dissecting tray ¥ masking tape

Instructions

1. Obtain the materials listed above. Throughout the test, keep the heart wet with the dropper.

2. Place the heart in the dissecting tray so that the inside of the heart is visible. Thread the string into the heart, starting where deoxygenated blood returns from the body and enters the heart. Continue threading the string through the heart and surrounding vessels in the direction that blood flows. Your string should end where oxygenated blood leaves the heart and goes back out to the body.

3. Next, label the string with masking tape as it enters and leaves the heart. Attach the masking tape to the string in the appropriate places to create 4 labels by writing the following on the tape. Include the arrows to show the direction of blood flow.

Ex:

4 Labels

FROM BODY---->

TO BODY---->

FROM LUNGS ---->

TO LUNGS ---->

4. On the following diagram:

a. Using a green colored pencil, draw arrows that show where you threaded the string through the heart. Make sure your arrows show the direction of blood flow.

b. Label the diagram as you did the string:

From Body; To Body;

From Lungs; To Lungs

c. Color the structures that carry oxygenated blood red and the structures that carry deoxygenated blood blue.

When you have finished threading the string through the heart and labeling the direction of blood flow, raise your hand to have the instructor check off your heart. Keep the heart at your table until you finish the rest of the test.

______________/21 points

5 a. Contrast the walls of the ventricles and atria.

b. Describe how the structure of the atrial and ventricular walls is related to their function.

6 a. Contrast the walls of the veins and arteries.

b. How is the structure of the vein and artery walls related to their function?

7. Describe the function of valves in the heart.

8. Sometimes people have heart valves that don't close completely. What effect would this have on blood flow in the heart?

When you are finished with the test, clean and return all equipment and put the heart in the place specified by your instructor.

How Do Different Practices Affect Heart Rate?

Teacher Preparation

Student Objectives

Survey 100 individualÕs resting heart rates and practices, attitudes or physical characteristics that could affect heart rate.

Construct tables and graphs to present the data collected in the survey.

Research information about practices of characteristics that are related to heart rate.

Present the information found to the class in a group presentation.

Materials Needed

Watch with second hand

Advance Preparation

Inform students of scoring rubric before they begin the test (you may want to hand them a copy of the rubric). Check out resources that could be left in the room for research or reference.

Time

3 class periods; surveying and researching should be done outside of class time

Student Background

Students should know how to properly take a resting heart rate, conduct a survey, and construct tables and graphs.

You may wish to brainstorm ideas with students at the beginning of the activity. Some ideas might include gender, age, physical activity, activity at the time they take the heart rate, time of day, before or after eating, etc.
