Unit 6:

Focus:

Students will be familiar with the relationship between senses and movement—that most of the time when they move a body part, that movement is initiated or guided by their senses. What they may not be familiar with are the changes that movement brings about in the circulatory and respiratory systems in the body. With every movement, the circulatory and respiratory systems of the human body will respond to supply the body with oxygen and other nutrients.

In this unit, students will consider the respiratory and circulatory systems and the role those systems play when students participate in a fun run. The circulatory system will move blood and oxygen through the bloodstream, where blood and oxygen are needed. The respiratory system will exchange the oxygen for the waste product carbon dioxide.

Students will also build on their understanding from previous grades about human body structures and their functions.
