Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Electrochemical Interface -> Facilitates student visualization of how different metals have different affinities for electrons (Redox potential), supporting Chemistry Module 101 (Understanding).
- Bio-Conductivity Modeling -> Enables the physical study of the human body's role as a conductor and the impact of skin moisture/salinity on electrical resistance (Applying).
- Electron Transfer Analysis -> Supports the Analysis of how a chemical reaction at the metal-skin interface generates a measurable flow of electrons from the more reactive metal to the less reactive one.
- Galvanic Potential Evaluation -> Allows students to Evaluate the effect of different surface areas, contact pressure, and physiological factors on the resulting current output (Evaluating).
International Logistics & Compliance
