Learning Goals and Intended Outcomes/Objectives Who? 25 biology majors What? Conceptual Physics course Learning Goal: Understand how a chemical battery works. Learning Objectives: 1.Identify key features of a battery. 2.Draw and label a battery and describe how it works. 3.Develop and explain an analogy of how a battery works to a concept in biology. 2

Assessment Summative Assessments For our tidbit Create a 3-D model of the analogy and explain how it works like a battery. Other possibilities Create a poster of your group’s analogy Exam Research paper Given specific materials, make a battery that will light up an LED‍ Research, design and create a battery out of new materials (no lemons or potatoes) Activities and Formative Assessments… 3

Questions from Reading Why does a battery need… 1) an anode? 2) a cathode? 3) an electrolyte? 4) a wire + bulb? 4

Think, Group, Share What would your life be like if you didn’t have batteries? 5

Complete the Puzzle Assemble 4 pieces Match labels and descriptions to each piece Draw arrow(s) indicating the flow of electrons Discuss separation of charge and potential 6 Objective: Identify key features of a battery.

AA Dry Cell Battery With your neighbor: Research a AA dry cell battery, a different form of a chemical battery Create a sketch on your whiteboard, labeling key features (& compare to puzzle) Compare your sketches with your group 7 Objective: Draw and label a battery and describe how it works.

Human Battery 8 The Matrix, 1999

Propose a Biological Analogy to a Battery In your group: Brainstorm possible analogies Select one for your final project Create a sketch on your whiteboard as a rough draft for your 3-D model Share 9 Objective: Develop and explain an analogy of how a battery works to a concept in biology.

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. 10 Objective: Develop and explain an analogy of how a battery works to a concept in biology.

Summative Assessments For our tidbit Create a 3-D model of the analogy and explain how it works like a battery. ‍ Other possibilities Create a poster of your group’s analogy Exam Research paper Given specific materials, make a battery that will light up an LED ‍ Research, design and create a battery out of new materials (no lemons or potatoes) 11

Batteries 12 Transform chemical energy into electrical energy Electrodes made of two different metals, immersed in an electrolyte solution (e.g., a dilute acid) Acid dissolves the zinc electrode; each zinc atom leaves 2 electrons behind & enters the electrolyte as a positive ion (zinc → negative) Electrolyte becomes positive; attracts electrons from carbon electrode (carbon → positive) End result: a potential difference between electrodes

Learning Goal Understand how a chemical battery works. 13

Learning Objectives 1.Identify key features (electrodes, electrolyte, separation of charge, connecting wire, etc.) of a battery. 2.Draw and label a battery and explain how it works. 3.Develop and explain an analogy of how a battery works to a concept in biology. 14
