Life Sciences:
2b. Students know how blood circulates through the heart chambers, lungs, and body and how carbon dioxide and oxygen are exchanged in the lungs and tissues.

6g. Record data by using appropriate graphic representations (including charts, graphs, and labeled diagrams) and make inferences based on those data.

Extension:
Grade 7- Physical Principles in Living Systems
6j. Students know that contractions of the heart generate blood pressure and that heart valves prevent back flow of blood in the circulatory system.
7d. Use a variety of print and electronic resources (including the World Wide Web) to collect information and evidence as part of a research project.

Using their science text, students will study the circulatory system.

Students will create diagrams or models illustrating how the circulatory system works.

Students will learn about ways of preventing heart disease and maintaining good cardio-vascular health.

Movement Skills and Movement Knowledge
As students continue to improve in motor performance, they become more proficient in basic skills, such as running, jumping, and throwing.

Grade 7 Extension
Seventh graders are also able to understand the interrelationship of the health-fitness components in the development of optimum health and thus to select specific exercises for each component. This is an appropriate time to introduce the FIT guidelines for physical exercise, which are the appropriate frequency, intensity, and time required for benefits to be accrued in each health-fitness component. Students should learn the principles of overload, progression, and specificity in physical conditioning
