1. The Human Circulatory System Mrs. Lucas 8 th Grade Science Nikki Lucas University of Phoenix CMP 555 – Designing and Producing Educational Technology Thomas Kelly March 2, 2009

2. Introduction This unit of study is meant to increase your awareness of the human circulatory system, its major parts, the functions of these parts, as well as how these parts work together with those of the previously studied respiratory system to promote overall health in the human body. This unit of study is meant to increase your awareness of the human circulatory system, its major parts, the functions of these parts, as well as how these parts work together with those of the previously studied respiratory system to promote overall health in the human body.

3. Your objective is… In this activity, you are expected to learn the parts of the human circulatory system along with their corresponding functions. In this activity, you are expected to learn the parts of the human circulatory system along with their corresponding functions.

4. Overview: Major Parts of the Circulatory System Heart Heart –Atria –Ventricles –Valves Blood Blood –Plasma –Platelets –Erythrocytes –Leukocytes Blood Vessels Blood Vessels –Arteries –Veins –Capillaries

5. Directions: The following is a breakdown of individual and group work that you will complete during this unit of study. Individual Work Individual Work –KWL chart regarding the circulatory system. –Labeled diagram of human heart. –Manipulation of human body model to properly place circulatory system parts. –Answer teacher questions regarding human circulatory system, and its link to the respiratory system. Group Work: Group Work: –Worksheet booklet identifying parts of circulatory and related systems, along with corresponding quiz. –Access interactive websites that help in learning the parts of the human circulatory system. –Construct a Word report or PowerPoint presentation addressing one disorder of the human circulatory system. Reports will be presented to the class.

6. KWL Process: The “K” and the “W” Before beginning instruction, begin your KWL chart provided by the instructor. Fill in the following: Before beginning instruction, begin your KWL chart provided by the instructor. Fill in the following: –K: What do you already know about the human circulatory system? –W: What do you want to learn about the human circulatory system?

7. Let’s begin… Take out your circulatory system booklet handouts. Take out your circulatory system booklet handouts. With your partner, read through the information provided in the booklet, and complete the corresponding activities and quiz at the end. With your partner, read through the information provided in the booklet, and complete the corresponding activities and quiz at the end. Once you have finished, see me for feedback on your completed booklet. Once you have finished, see me for feedback on your completed booklet.

8. Notes: Blood’s role in the circulatory system: Blood is made up of: Blood is made up of: –Red Blood Cells (Erythrocytes) – carry oxygen to the body’s cells, and remove carbon dioxide waste from these cells. –White Blood Cells (Leukocytes) – they help fight infection in the human body. –Plasma – this is the lubricant for red blood cells – it is the water portion of blood that allows erythrocytes to flow steadily. –Platelets – these are produced when there is a break in a blood vessel due to an injury. They produce scabs and help clot blood, preventing major blood loss in the event of minor-medium severity injuries.

9. Notes: The role of blood vessels: Arteries: These are the largest vessels in the human body. They carry blood away from the heart and to the rest of the body. Arteries: These are the largest vessels in the human body. They carry blood away from the heart and to the rest of the body. Veins: These vessels are medium-sized, and carry blood back to the heart once it has circulated through the body. Veins: These vessels are medium-sized, and carry blood back to the heart once it has circulated through the body. Capillaries: These vessels are the smallest. Their walls are thin and porous, therefore making it easy for oxygen and carbon dioxide gases to enter and exit the bloodstream. Capillaries: These vessels are the smallest. Their walls are thin and porous, therefore making it easy for oxygen and carbon dioxide gases to enter and exit the bloodstream.

10. Notes: The basic role of the human heart: The human heart is divided into chambers: The human heart is divided into chambers: –Left and Right Atria: These two smaller chambers are located at the top of the heart. Blood pumps through these chambers after returned by the veins. –Left and Right Ventricles: These two lower chambers are larger, and squeeze blood from the heart through arteries and to the rest of the body. –Valves: These are located between atria and corresponding ventricles; they are a passageway for the flow of blood from one chamber to the next.

11. We will now move into the computer lab, where you will each work with a partner at your own computer terminal. Once you are in the lab, you will access the following sites: Once you are in the lab, you will access the following sites: The heart with labels: –http://www.edhelper.com/teachers/health_He art_with_Labels.htm http://www.edhelper.com/teachers/health_He art_with_Labels.htmhttp://www.edhelper.com/teachers/health_He art_with_Labels.htm The Circulatory System Movie: –http://kidshealth.org/kid/htbw/CSmovie.html. http://kidshealth.org/kid/htbw/CSmovie.html

12. Once you are in the lab: 1. Access the first site, with the labeled heart. Check your own heart diagram and make certain your labels are correct. 1. Access the first site, with the labeled heart. Check your own heart diagram and make certain your labels are correct. 2. Access the second site. This site provides audio and video – which we will view together using the SyncronEyes technology. 2. Access the second site. This site provides audio and video – which we will view together using the SyncronEyes technology. 3. Using the video regarding the circulatory system, write one additional piece of information regarding each system part into your graphic organizer used during notes. 3.

Should you have any questions, do not hesitate to ask the teacher for help!!! Should you have any questions, do not hesitate to ask the teacher for help!!!

13. Using http://www.google.com : http://www.google.com Search for disorders or diseases of the circulatory system. Search for disorders or diseases of the circulatory system. Complete either a one page typewritten report (double spacing, size twelve font, one inch margins all around) or a PowerPoint presentation (minimum of 5-8 slides) summarizing the definition, causes, symptoms, and treatments or cures for this disorder/disease. Complete either a one page typewritten report (double spacing, size twelve font, one inch margins all around) or a PowerPoint presentation (minimum of 5-8 slides) summarizing the definition, causes, symptoms, and treatments or cures for this disorder/disease. You and your partner will report back to the class on your chosen disease. You and your partner will report back to the class on your chosen disease.

14. Now, using your knowledge from the previous unit: Individually answer: Individually answer: –How do the human respiratory and circulatory systems work together to promote human health in the body?

15. Revisiting the KWL: Filling out the “L” Upon completion of this activity, you must revisit your KWL chart, and fill in the “L” component. Upon completion of this activity, you must revisit your KWL chart, and fill in the “L” component. –L: What you have learned about the circulatory system that you did not know before studying this unit.
