Essential Question
What is the function of the circulatory system in the human body?
Content Knowledge: Declarative, Procedural
Declarative:
Procedural:
PROCEDURE
(Chronologically ordered description of all teacher & student activities and interactions.)
As the initiating activity, the class will view video "Hemo the Magnificent" and then teacher will initiate a discussion about the function of the circulatory system. The discussion will lead to identification and labeling of the parts of the circulatory system including:
parts of the heart
blood vessels
parts of the blood
The discussion will also include the parts of a cell, including:
cell membrane
nucleus
cytoplasm
organelles
The media specialist will read Parts, by Tedd Arnold, during a library class. The media specialist will also offer instruction in use of book marked web sites.
The teacher will give each student a diagram of the human heart to label and color appropriately.
A Library class will be used to view the CD-Rom Human Body. Students will complete the activity sheets that follow along with the CD, Cells and Circulation 1 & 2. They will discuss their answers at the end of the class.
Other library classes and free time will be used for independent investigation of book marked web sites that discuss the circulatory system. Students will be responsible for logging on and working their way through all three web sites: How the Body Works; Science Fact File: Inside the Human Body; and A Look Inside the Human Body. Students will use activity chart to document their independent progress.
Students will take and record their own pulse rates, both at rest and after gym. (see activity page Pick Up the Beat)
As a culminating activity, each student will use the computer program Inspiration to create a flow chart of the circulatory system. Instruction in the use of this program will be given in the media center. Students will use class and library time to complete this activity, print their charts and discuss their projects with the class.
INSTRUCTIONAL/ENVIRONMENTAL MODIFICATIONS
If students have fine motor or writing difficulty, enlarged or completed diagrams may be provided, or students may dictate to a scribe who will fill in the appropriate material for them. If Internet access is available in the classrooms, students may access the appropriate web sites there, as well as in the media center.
TIME REQUIRED
The experience will require approximately 5 - 8 45 minute class periods.

ASSESSMENT PLAN
(Include samples of rubrics, checklists, etc.)
Students will produce an appropriately labeled diagram.
Students will use a prepared chart to record their heart rates at various times
of the day.
Students will use teacher-generated check list to track their progress through
independent Internet activities.
Students will produce a flow chart explaining this body system, using the computer program "Inspiration".
Inspiration Rubric – Circulatory System
How clearly you organized and expressed the key points of the Circulatory System
|
4 Very clearly – you have included all the parts of the circulatory system |
3 Somewhat clearly – you have included most of the parts of the circulatory system |
2 I'm a little confused – some important parts of the circulatory system are missing |
1 Not yet – there are only a few parts of the circulatory system on your chart |
How well you explained each part of the circulatory system
|
4 Very well – you have a clear understanding of what each part does / included correct definitions for each part |
3 This is OK! You have included correct definitions for most parts of the circulatory system |
2 I only find a few definitions, or some of your definitions are incorrect |
1 Not yet – there are no definitions of the terms / the definitions are incorrect |
How effective is your Inspiration chart?
|
4 Great job! Your chart follows a correct pattern to illustrate the circulatory system. You have used graphics and color changes effectively, too! |
3 Some good parts. You might want to consider using a few more graphics and color changes to enhance your chart. |
2 Needs some zing! Few or no graphics. |
1 Not yet – No Inspiration chart printed out. |
How correctly you use grammar, spelling, and punctuation
|
4 Great! No errors! |
3 Good job! Only a few mistakes. |
2 Be sure to edit your work carefully! |

NAME
Your pulse is caused by the stopping and starting of the blood as it rushes through your arteries. You can feel your pulse rate at any spot an artery is near the surface of the skin. These spots are called pulse points. One pulse point is located on the inside of your wrist.
Name some other pulse points.
Your pulse rate changes during different kinds of activities. Check your pulse rate after doing these activities.

CELLS AND CIRCULATION
Assessment Sheet 1
_____________________________________________________
STUDENT NAME: _____________________
Directions: Use the following terms to fill in the blanks below:
left ventricle
right ventricle
aorta
left atrium
right atrium
capillaries
Blood flows throughout the human body in the following way:
From the lungs, fresh oxygen is transported to the heart, where the oxygen first enters the _________ . The blood then enters the _________ before it is pumped through the __________ to the _________ , where oxygen is exchanged for carbon dioxide in the cells of the body. After returning from the body, the blood then moves from the ________ to the ________ and finally back to the lungs, where carbon dioxide can be exhaled and fresh oxygen can be absorbed.
CELLS AND CIRCULATION
Assessment Sheet 2
_____________________________________________________
STUDENT NAME: ___________________________
Directions: Determine if the following statements are true or false:
1. ______ Red blood cells transport oxygen and carbon dioxide. They are found in the plasma of the blood.
2. ______ Cell membranes enclose the DNA of the cell.
3. ______ White blood cells are responsible for the clotting behavior of blood.
4. ______ Valves in the heart prevent blood from flowing in the wrong direction. The movement of blood through the valves also accounts for the sound of the heart beating.
5. ______ Kidneys act as filters that remove wastes from the blood.
6. ______ Plasma is the jellylike material found in every cell between the nucleus and the cell membrane.
7. ______ Metabolism describes the use of oxygen by the body to convert food into usable energy.
GLOSSARY
artery: vessel that carries blood away from the heart.
atrium: one of the chambers of the heart that receives blood from the lungs or another part of the body and passes blood on to the ventricles.
blood: the fluid that transports materials through the body.
capillary: the smallest blood vessel where exchange of food and gas particles occurs.
cytoplasm: all the protoplasm between the nucleus and the cell membrane.
DNA: the genetic material of all living things.
membrane: the wall of a cell through which materials can move in and out.
nucleus: the center organelle of a cell where the genetic material DNA is stored. Acts as the "brain" of the cell.
organelle: a term to describe the many specialized parts of a cell.
plasma: the liquid portion of the blood.
platelet cell: a type of specialized blood cell responsible for clotting.
red blood cell: a small blood cell that carries oxygen and carbon dioxide to and from the body’s cells.
vein: vessel that carries blood toward the heart.

Directions – Use the book marked web site A Look Inside The Human Body to answer these questions about the circulatory system. Click on the link to the circulatory system to start.
Where is the heart positioned?
Complete these sentences:
Blood that is rich in oxygen appears
Blood that is poor in oxygen appears

Blood returning to the heart travels in
How many blood cells in a droplet of blood?
How long do blood cells live?
STUDENT WORK
(Include samples of student work showing different levels of performance.)
Student work will be included when the classes finish this experience.
REFLECTION
Students will need access to enough computers to work through the web sites. Time will need to be set aside for this activity, either in library class or in their science class time. It will need to be determined whether or not students should visit all of the listed web sites, or if they will be able to access enough information from visiting only a select few. Time and the number of available computers will be the determining factor.
The Math / Science / Technology Standard 2 – Information Systems - will be assessed by using the Inspiration Rubric. The requested copy of a heart picture for students to color and label was a scanned document, and may not be able to be attached to this experience at this time, as Title III requested that no scanned images be used. However, a paper copy will be sent to Title III to see whether they are able to add it to the experience.
