Each group of students (3-4 students), will have a system assigned to them. Each system is color coded and the handout includes a "System Man" outline and a copy of systems/ organs that fit perfectly into the man. I also included a chart (organizer) for students to write the function of each system, and how each system relates to the function of other systems. If you are in Texas, you have noticed that our STAAR test for 8th grade has asked questions about how multiple systems function together. This is a great activity to make sure our kids are thinking of how they are related to each other. Students can present their system or you can have them do a stations/gallery walk to collect information for all the systems.
