Author: Dawn Ross
Subject: Cardiovascular System
Grade: 6-9
Course: Health
Title: Know your Heart Parts and Functions

Length of Lesson: One class period
Materials Needed: Heart puzzle (teacher- made)
Heart handout
Power Macintosh G3 computer
Larger screen and projector
A.D.A.M. software

Standards-Based Outcomes (MDE):

Health:

Content Standard 1: All students will apply health promotion and disease prevention concepts and principles to personal, family, and community health issues.

1. Describe the interrelationships of and the physiological changes in body systems.

Science:

III. Using Scientific Knowledge in Life Science in Real-World Contexts

Content Standard III, 2: All students will use classification systems to describe groups of living things; compare and contrast differences in the life cycles of living things; investigate and explain how living things obtain and use energy; and analyze how parts of living things are adapted to carry out specific functions. (Organization of Living Things)

4. Explain how selected systems and processes work together in plants and animals. (Key concepts: Systems/Processes-- digestion, circulation, respiration, endocrine, reproduction, skeletal, muscular, nervous, excretion, transport, growth, repair. Real-world contexts: Interrelations of body systems during selected activities, such as among skeletal, muscular, circulatory, and respiratory systems during physical exercise.)

Prior Knowledge:

Students need to know the purpose of the heart and cardiovascular system.

Cue Set:

• Why is the heart important? Discuss with the students.
• What is the function of the heart? Discuss with the students.
  -Show the cardiovascular system with the heart and vessels in place with the A.D.A.M. software
  -Ask the students if any of them know what the structures are.

Best Shot Instruction:

• Pass out heart puzzles which have been constructed by the teacher.
• Discuss each puzzle piece and its respective part's location and function in the heart.
  • Puzzle pieces should include: left auricle, one way valve, left ventricle, right ventricle, right atrium, aorta, cardiac vein, coronary sinus, inferior vena cava, pulmonary arteries, pulmonary trunk, superficial vena cava, and pulmonary veins.
• The computer program A.D.A.M. will be on the main screen in front of the room. The teacher uses one part of the program for a visual identification of heart parts. Functions of all of the heart structures will be seen with the program's animation.
• The students work in pairs to assemble the puzzles.

Reteaching and Enrichment:

• The class works on a 3-D interactive puzzle as a group. The teacher selects students to work individually on the animated puzzle.
• Students are given handouts with heart parts identified.

Review and Closure:

Students hold up heart puzzle pieces when verbally cued by the teacher. By having the students hold up pieces, the teacher will see the overall information retained by the class.

Assessment:

A. Formative Assessment (Teacher Observations):

-The instructor will walk around the room, speak with the students, and ask questions as they put their heart puzzles together.

-By observing the class construct the 3-D interactive heart puzzle, the instructor will detect the amount of information retained.

-At the end of the class period, the instructor will know which specific students are having difficulty learning the heart parts by observing the students as they hold up the heart puzzle pieces. The students who are having difficulty will have a slower response when finding puzzle pieces.

B. Summative Assessment:

-The students will independently fill in worksheets and label heart parts.
