5. Domain-General Investigations (minimizes the role of prior knowledge) - Generates observations/measurements that induce a claim that can account for a pattern (Discovery) – Example – Law of the Pendulum: isolate the 3 variables (length of string, size of weight, height weight is released) to determine which variables influences the period/time of swing. (Requires only one lesson)

6. Domain-Specific Investigations (infuses the role of prior knowledge) -Tests an existing model or theory (Confirmation/Verification) – Example – Challenge students to determine all the factors that affect the swing of a pendulum, including mathematical relationships. Then, without allowing students to test, have them predict the length of time of swing of a randomly configured pendulum. (Requires a sequence of lessons)
