Planning for this investigation In the investigation plan, students describe: ● How the change in the external environment is to be measured or identifed; ● How the response of the cell will be measured or identifed; ● How the stabilization or destabilization of the cell’s internal conditions will be measured or determined. ● The experimental procedure, the evidence derived from the data, and identifcation of limitations on the precision of data to include types and amounts; and ● Whether the investigation will be conducted individually or collaboratively. Collecting the data Students collect and record: ● Changes in the external environment and cell responses as a function of time. Refning the design Students evaluate their investigation including: ● Assessment of the accuracy and precision of the data, as well as limitations (e.g., cost, risk, time,) of the investigation, and make suggestions for refnement; and ● Assessment of the ability of the data to provide the evidence required. If necessary, students refne the investigational plan to produce more generalizable data. *When “describe” is referenced, any of the following descriptions could be used: written, oral, pictorial, and kinesthetic. Standard 2.6 Asking Questions: Addressing phenomena of the natural world or scientifc theories Students use models of organ systems, organs and their component tissues to formulate questions, the answers to which would clarify: ● The functions of at least two major body systems in terms of contributions to overall function of an organism, ● Ways the functions of two different systems affect one another, ● A system’s function and how that relates both to the system’s parts and to the overall function of the organism, and ● How feedback mechanisms maintain homeostasis. Evaluating empirical testability Students evaluate the given questions in terms of whether or not answers to the questions would provide means to empirically determine ● How the interaction between systems provides specifc functions in multicellular organisms. Engaging in Argument: Developing the claim Students develop a claim that is supported by generalizing from multiple sources of evidence, which includes the following idea: ● The relevant parts (e.g.; organ systems, organs, and their component tissues) and processes (e.g., transport of fuids, motion) of body systems in multicellular organisms work to maintain homeostasis through feedback mechanisms.
