MS - LS1 Bodies and Systems - FINAL (WND 12-6-13)

Module: Bodies and Systems

DCI: LS1.A (C) In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.

PE: MS-LS1-3 Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

[Clarification Statement: Emphasis is on the conceptual understanding that cells form tissues and tissues form organs specialized for particular body functions. 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.]

Each question should avoid asking specifically about the function of a single system.

The only acceptable questions are those that discuss interactions between two or more systems.

Possible Question Starters:

- Which of the following observations provides the best evidence to support the idea that the body is a system of interacting subsystems? (correct answer =  two systems interacting, wrong answers would be single systems)

- Which of the following observations about the removal of waste provides evidence for the idea that the human body is a system of interacting subsystems? (correct answer =  two systems interacting, wrong answers would be single systems)

- Which of the following will be the most similar? (correct answer = two cells in the same tissue, wrong answers = two organs in the same system, etc.)
