Here is another addition to the lessons on the analogy between a body organ/system and a machine. These work well for STEM lessons because they bring in two areas of science: Anatomy and Physiology/Biology and Physics/Engineering. For example, in this lesson, we compare the way electrons move along a wire to the way ions move back and forth along the axon of a neuron in order to send an impulse. It works for Physics where it talks about electricity and touches upon engineering too. It works for Anatomy and Physiology and Biology under the NGSS standards HS-LS1-2,3 where the emphasis is on the organization of body systems. The second page gives more detailed info on the making of an ion and the Action Potential steps.

NGSSHS-LS1-3
Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis. Examples of investigations could include heart rate response to exercise, stomate response to moisture and temperature, and root development in response to water levels. Assessment does not include the cellular processes involved in the feedback mechanism.
NGSSHS-LS1-2
Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms. Emphasis is on functions at the organism system level such as nutrient uptake, water delivery, and organism movement in response to neural stimuli. An example of an interacting system could be an artery depending on the proper function of elastic tissue and smooth muscle to regulate and deliver the proper amount of blood within the circulatory system. Assessment does not include interactions and functions at the molecular or chemical reaction level.
