Learning Goals and Intended Outcomes/Objectives
Who? 25 biology majorsWhat? Conceptual Physics course
Learning Goal:
Understand how
a chemical battery works.Learning Objectives: Identify key features of a battery.Draw and label a battery and describe how it works.Develop and explain an analogy of how a battery works to a concept in biology.

Questions from Reading
Why does a battery need… an anode? a cathode? an electrolyte? a wire + bulb?
4Slide5
Think, Group, ShareWhat would your life be like if you didn’t have batteries?
5Slide6
Complete the Puzzle
Assemble 4 piecesMatch labels and descriptions to each pieceDraw arrow(s) indicating the flow of electronsDiscuss separation of charge and potential
6
Objective: Identify key features of a battery.Slide7
AA Dry Cell BatteryWith your neighbor:
Research a AA dry cell battery, adifferent form of a chemical batteryCreate a sketch on your whiteboard, labeling key features (& compare to puzzle)Compare your sketches with your group

The Matrix, 1999Slide9
Propose a Biological Analogy to a Battery
In your group:Brainstorm possible analogiesSelect one for your final projectCreate a sketch on your whiteboard as a rough draft for your 3-D modelShare
9
Objective: Develop and explain an analogy of how a battery works to a concept in biology.Slide10
Next Step: Final Project
In your group:Create a 3-D model of the analogy you’ve proposed and explain how it works like a battery.

Batteries
12
Transform chemical energy into electrical energy
Electrodes made of two different
metals, immersed in an electrolytesolution (e.g., a dilute acid)Acid dissolves the zinc electrode;each zinc atom leaves 2 electronsbehind & enters the electrolyte asa positive ion (zinc → negative)Electrolyte becomes positive; attracts electrons from carbon electrode (carbon → positive)End result: a potential difference
between electrodesSlide13
Learning Goal
Understand how a chemical battery works.

Learning Objectives
Identify key features (electrodes, electrolyte, separation of charge, connecting wire, etc.) of a battery.
Draw and label a battery and explain how it works.
Develop and explain an analogy of how a battery works to a concept in biology.
