Lesson: Experimental Measurements Physics

In this lesson, we will learn how to recognize types of experimental variables and to understand how variables are used in performing experiments.

Lesson Plan

Students will be able to

define terms related to measurements used in experiments such as quantity, value, variable, constant, universal constant, independent variable, dependent variable, and (un)controlled variable,
understand that a constant that is not a universal constant is effectively a controlled variable except that the experimenter did not actively control the variable and just measured it to ensure its constancy (or even just assumed its constancy),
explain the purpose of experiments as tests of predictions,
explain the usefulness of repeating or replicating experiments in identifying anomalous measurements.
