Stoichiometry: Percent Yield

This NGSS aligned lesson builds on the stoichiometry and limiting and excess reactants concepts. The emphasis of this lesson is on concept development of percent yield. Students will distinguish between actual yield, theoretical yield, and percentage yield. Conceptually, students will understand that the percent yield tells chemists about the efficiency of a reaction. Chemists can then work to improve efficiency in several different ways, and increase percent yield. Students will calculate percent yield given the actual amount and the amount of reactant(s). The homework and exit ticket are differentiated for honors and standard classes. This lesson goes well with my Conversion Game-The Stoichiometry Edition. Or, try the Stoichiometry Scavenger Hunt, or stoichiometry task cards with white boards to give students more practice. Objectives: Distinguish between theoretical yield, actual yield, and percentage yield. Calculate the percentage yield for
