This resource is a paper, printable unit on the circulatory system. This product provides your students with informational text passages, interactive notebook flaps, videos, response pages, and a quiz. Students will make arguments from evidence and will learn about the organization of the human body: cell-tissue-organ-system. They will learn that the body is made up of cells, which make up tissues, which make up organs. Together, specialized cells, tissue, and organs work together in a system. They will learn what the circulatory system is and all the components of it. They will learn about blood and the function of different parts of human blood. They will also label a heart and show the flow of blood through it.

Examples could include the interaction of subsystems within a system and the normal functioning of those systems.] [Assessment Boundary: Assessment does not include the mechanism of one body system independent of others. Assessment is limited to the circulatory, excretory, digestive, respiratory, muscular, and nervous systems.]
