The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best. Learners will explore a variety of relationships using pennies, pressure, temperature, light, and pendulums. They will then determine the algebraic equations that best represent the variables involved in each situation. Each of the six activities is listed and discussed separately in this lesson plan so that they can be modified to meet learners' needs.
