Use scientific equipment to gather and analyze data on human physiology.
Understand how the body systems integrate for human health.
Communicate concepts related to the human body through written, verbal, or other modes, including graphing and data presentation.
Evaluate behaviors’ effects on health related to human physiology and anatomy.

Statewide General Education Outcomes:

Gather, comprehend, and communicate scientific and technical information in order to explore ideas, models, and solutions and generate further questions.
Apply scientific and technical modes of inquiry, individually, and collaboratively, to critically evaluate existing or alternative explanations, solve problems, and make evidence-based decisions in an ethical manner.
Assess the strengths and weaknesses of scientific studies and critically examine the influence of scientific and technical knowledge on human society and the environment.
