Five-Day Unit Plan:Acid-Base

Equilibria

Learner Analysis21 students11th-12th grades Lower to middle classMost from Appalachian culture, one student from Germany All have previous introductory chemistry knowledge Hands-on learners, with a few exceptions Understand/apply concepts well through homework

ObjectiveStudents will correctly solve calculations involving acid-base equilibrium constants by manipulating variables, performing a laboratory experiment, and relating back to previous concepts of stoichiometry and equilibrium with 80% accuracy by the end of the unit.
