Students will use their knowledge of simple series circuits from prior activities and a multimeter to explore electrical resistance in the human body.
Students will measure how electrical resistance changes over distance in a human arm.
Students will explore how the concentration of a solution can change the electrical resistance of that solution. This will be related to the concept of dehydration and how bioelectrical impedance is dependent on the hydration levels in the human body.
Using scenario cards, students will analyze human conditions to determine how they affect the calculated percent of body fat in a human being.
Body composition, fat mass, fat-free mass, resistance, reactance, impedance, bioimpedance, fat content, electrical bioimpedance, body fat
