Aluminum-Air Battery
• Formal formative • Informal formative• Technology
Aluminum Air Battery“The current is produced by redox reactions of the aluminum foil. Al ionizes to form positive ions in the solutions; this releases electrons, producing current, which travels along the copper wire.”

Reflections on Teaching
• Differentiated Learning– Important to understand student differences,
and put them in groups that result in efficiency
– External websites facilitate differentiate learning
– SmartBoard should be leveraged to make engaging PowerPoints
Reflections on Teaching
• Collaborative Learning– All aspects of the project
should support collaborative learning.
– Don’t trust, or make deals with, students.
– Assess students understanding to ensure they are ready for the project
Reflections on Teaching
• Planning for Instruction– Be prepared for change– More planning = increase in classroom
management • Assessment
– Use a quiz as a way to hold students accountable and assess student understanding before the project
– Be consistent with exit slips– Keep notes of student conversations – Get organized
