What Do You Know About the Heart? (assessments)Lesson
To gauge their understanding of the heart and circulatory system, students take a pre-assessment, which will be revisited during post-assessment.
A System of TransportLesson
Students work in teams to simulate the movement of blood through the circulatory system by transferring liquid into—and through—a series of containers.
Students investigate and draw conclusions about the movement of dissolved substances, and about the importance of organisms’ internal transport systems.
It Begins with the HeartLesson
Students learn basic information about the heart, its role in circulation, and its external appearance.
The Heart is a PumpLesson
Students learn about the internal structures of the heart, and the roles these structures play in circulating blood to the lungs and the rest of the body.
Examining the HeartLesson
Students examine sheep or chicken hearts to learn about heart structure and the flow of blood through the heart.
Heart Rate and ExerciseLesson
Students measure and compare their heart rates before and after a variety of physical activities, and also compare their heart rates to those of other students in their groups.
What Is Blood Pressure?Lesson
Students measure their own blood pressure and learn about the health effects of high blood pressure.
Challenge of MicrogravityLesson
Students use water balloons to simulate and investigate the effects of gravity and microgravity on the distribution of fluid in the body.
