LESSON 1 Pulse of Life Objective: Calculate your pulse rate and explore how heart rate is affected by various activities.
	LESSON 2 Keeps on Pumpin' Objective: Measure and calculate heart rates per minute and for other units of time. Determine the amount of blood pumped by your heart during various intervals of time.
	LESSON 3 Under Pressure Objective: Investigate the implications of blood pressure.
	LESSON 4 Sounds of the Heart Objective: Investigate the sounds of the heart, construct a stethoscope, and explore the workings of valves.
	LESSON 4a Valves and Pumps Objective: Students will see how valves and pumps work in concert to move blood through the circulatory system.
	LESSON 5 Lub Dub (Valves) Objective: Investigate the source of the sounds of the heart.
	LESSON 5a Heart as a Pump Objective: Name and locate the major areas and structures of the heart and trace the pathway of the blood through the heart, lungs, and body.
	LESSON 6 Go With the Flow Objective: Name and locate the major areas and structures of the heart and trace the pathway of the blood through the heart, lungs, and body.

THE LUNG LESSONS
	LESSON 7 Lung Model Objective: Discover the function of various parts of the body's respiratory system.
	LESSON 8 Ins and Outs of Respiration Objective: Determine their respiratory rate and explore the factors that affect breathing rate.
	LESSON 9 Catch your Breath Objective: Measure lung capacity and explore factors that affect the amount of air the lungs can hold.

EXTENSIONS
	LESSON 10 O2 CO2 Skit Objective: Act out the flow of blood in the circulatory system.
	LESSON 11 X-rays Objective: Students will examine chest x-rays of adults and children.
