Circulatory Unit Group Assessment-Building an Artificial Heart Model
(30 points)
Purpose: Students will work together in teams to connect their knowledge of the circulatory
system by designing, building and demonstrating a working artificial “heart”
Criteria checklist: Use the following checklist to make sure that you are completing all of the
requirements.
___Each of the following structures must be present to demonstrate the flow of blood through
the heart and the body.
___
___
___
___
___
___
Right Atrium
Right Ventricle
Left Atrium
Left Ventricle
Aorta/Vena Cava
Pulmonary Artery/ Pulmonary Vein
___ All structures must be properly linked to one another according to their physiological
relationship (e.g., the ventricles should not be able to pass “blood” directly between each other.
___ Each “heart” must have a self-contained, sealed and continuously flowing water solution
(“blood”), so that no “transfusions” are needed and no “bleeding” occurs when the heart is
functioning.
____ The heart must be able to move the “blood”, but does not have to function autonomously
(on its own) (i.e., students may produce the necessary forces)
____ Everything (i.e., valves, chamber contractions) must work in the correct order and manner
when the model is operating.
____ The structure of the model does need to reflect exact anatomy, but must support proper
functioning of the artificial heart.
____ Parts of the working artificial “heart” are labeled and arrows are used to show the correct
direction of flowing “blood”.
Team Arrangements:

Students are to work in teams of three or four.

If members of the team are absent, the assignment is still expected to be completed on
time.

If a member of the team is absent for 2 or more periods; the member will have to design and
complete a model on his/her own before or after school
Time Frame: 6 Class Periods
Period 1:
Assessment explanation, team formation, design and gathering of materials
Period 2:
Construction and Experimentation
Period 3:
Revisions and practice for presentation of model
Period 4:
Written Individual Explanation of model and how it compares to an actual heart.
Period 5:
Group Presentations to peers
Period 6:
Review packet for written assessment/presentation to teachers
Materials that will be available to each team:

4 vinyl examination gloves

1 meter of 5/16 in. plastic tubing

Small tube of silicon aquarium sealant or bath caulk (you must wear gloves when using these
sealants)

4 clamps

If any other materials are needed, speak with me in advance (prior to building)

Building an Artificial Heart Model Rubric (12 pts)
Structural Components (each worth 1 point)
_____ has four chambers
_____ atria chambers are the same size
_____ ventricle chambers are larger than atria chambers
_____ has 4 valves
_____ the placement of the tubing and valves is correct.
_____ tube lengths are reasonable given the distance the blood flows from one structure
to the next. (example: heart to lungs distance vs. heart to body distance)
_____ water (“blood”) is part of the model and does not leave the model.
Functional Components: (each worth 1 point)
_____The atria contract simultaneously.
_____ The valves function correctly.
_____ The ventricles contract simultaneously.
_____ Valves work to cause water (blood) to flow in one direction.
_____ There are no leaks.
