Topic: Measurement and the Language of Physics
Unit Title: Dimensional Analysis

Your students will need to understand how to cancel units before they can solve problems using dimensional analysis. Beginning with simple one-step conversions, it progresses to problems requiring multiple conversions. Students will like the informal writing style by the author, whose motto is "If I can do this stuff, then so can you!"
