This is an AP chemistry flipchart that covers Chapter 3.1-3.5. This flipchart should take 1-2 days to complete. Ch 3.1-3.5 covers calculating average atomic mass, calculating the mole, % composition, empirical and molecular formulas. There is a note packet that can be downloaded also that students can use to follow along and solve the problems. The teacher can use ACTIVexpressions on the many open ended questions, you can just send students to the board to solve the problem, or both.
