Homeostasis, the 5 levels of organization of living things, and body systems all tie in together and can be used in a 2 day classroom activity to help students understand why and how they are related using C.E.R. (Claim, Evidence, and Response). C.E.R is one way to engage in argument through evidence which is required when using NGSS science standards. This activity will keep students busy while having time to discuss relevant matters with their classmates and get them thinking and writing about homeostasis and keeping our body systems stable. I have included everything you will need on one file. Anything you would like to print I made in white so it will come out clean and crisp for you.

5 Levels of Organization, Homeostasis, Body Systems Power Point
Life Science Standard 1.A states that by the end of grade 8 and by the end of grade 12 students will understand these related concepts.
Grade 8: Within cells, special structures are responsible for particular functions, and the cell membrane forms the boundary that controls what enters and leaves the cell. In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues or organs that are specialized for particular body functions. (Boundary: At this grade level, only a few major cell structures should be introduced.)
Grade 12: Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Outside that range (e.g., at a too high or too low external temperature, with too little food or water available), the organism cannot survive. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system.
