Assessing Competencies> Potential Modules or Threads
Below are some of the most relevant pages (HW, Clicker Questions, Quizzes and Exams, Readings) from Physics 131/132 that could be viewed as forming a chemical bond energy "thread" leading up to the ATP hydrolysis essay ("capstone assessment") on the first midterm exam in Physics 132. This includes some traditional discussion of potential energy not specifically related to bond energy, since that conceptual work is a necessary pre-requisite.
