Name: Whitney Sayuri Nekoba
Dates of Lesson: 6-7 March 2008
Title of Lesson:
School: Strath Haven High School
Class: Advanced Placement Biology
Circulatory System
Goals
• Review human disease assignment on respiration.
• Information about the circulatory system will be given through a lecture format.
• A pig heart dissection will help students to explore the various structures of a mammalian
heart.
Learning Objectives
Students will be able to:
• compare and contrast open and closed circulatory systems.
• identify and compare the structure and function of the chambers, valves, and major
arteries of the heart.
• compare and contrast the structure of an artery and a vein.
• trace the steps of double circulation in mammals.
• complete a dissection of a pig heart.
Lesson Plan
Thursday, March 6, 2008
Teacher Prep:
Prepare PowerPoint or overhead projector slides for lecture. Photocopy
Circulation handout for students’ use in class.
Pre-Class Assignment:
Read Ch. 42 (pp. 871-886) (Campbell, Reece).
Continue your list of the vertebrate systems and their functions.
Review assignment on human respiratory diseases. Students will present findings.
Introduce circulatory system with activity to activate prior knowledge.
1. Class will brainstorm all words that are related to the circulatory system.
2. Students will self-assign themselves to different knowledge-level groups: expert,
proficient, approaching proficiency, and novice.
3. Expert group: Draw and label a human cardiovascular system (including organs, valves,
arteries, veins, etc.).
4. Proficient group: List all structures and accompanying functions of the human
cardiovascular system.
2
5. Approaching proficiency group: Make a concept map of all the words listed from the
class brainstorm on the board.
6. Novice group: Make a concept map of all the words that are familiar to them from the
class brainstorm.
7. Groups will present the assignment to the rest of the class, starting with the novice group.
The information from each presentation will build upon one another and will inform the
teacher on the level of knowledge of the entire class.
Start lecture on the vertebrate circulatory system.
1. Key Concept: Circulatory systems reflect phylogeny.
2. Key Concept: Double circulation in mammals depends on the anatomy and pumping
cycle of the heart.
3. Key Concept: Physical principles govern blood circulation.
4. Key Concept: Blood is a connective tissue with cells suspended in plasma.
Assessment:
• Three students (assigned) will research one disease each that affects the human
circulatory/cardiovascular system. For each disease, describe the: (1) symptoms and
ailment, (2) affected tissues and/or organs, (3) current treatments, and (4) potential for
cure or prevention.
Teacher Prep:
Prepare for Pig Heart Dissection Lab. Preparation should be set up for
groups of 2 or 3.
Friday, March 7, 2008
Pre-Class Assignment:
Re-read Ch. 42 (pp. 871-886) (Campbell, Reece). Complete pig
heart vocabulary list.
1. Pig Heart Dissection Lab – Handout
2. Thought Question: Explain each of the following in terms of function related to
structure.
The atria have thinner walls than the ventricles.
The left ventricle has a thicker wall than the right ventricle.
Blood pressure in the aorta is the greatest in the body.
3
Oxygen-rich blood never mixes with oxygen-poor blood in a fourchambered heart.
Artery walls are thicker than vein walls.
Capillaries are numerous and their walls have to be only one cell thick.
Assessment:
• Go over Thought Question as discussion in class today or at the start of class tomorrow.
• Have students answer the post-lab questions on Handout and turn in answers tomorrow.
• Points may be deducted from post-lab questions if clean-up is not thorough as per
Handout directions.
