The NGSS science standards require a knowledge of the organization of the human body from cells to organs to organ systems, etc. For students in honors classes, etc. I wanted a little more detail than would be found on my simpler worksheet (Organization of the Body 1) Of course, we know that organs are made of more than one tissue, and that some tissues are made of more than one kind of cell. This worksheet enables them to use research methods to complete it. I have included an example of the stomach for you.
