Intent In these activities, students will solve the unit problem and build an experimental model to confirm their solution.

Mathematics The mathematical focus of the activities in Measuring and Predicting is on collecting data relating the length of a pendulum to its period, fitting a function to those data, and then making a prediction for the time it takes a 30-foot pendulum to complete 12 swings. The relationship between the period and the length is a function of the form y=cx size 12{y=c sqrt {x} } {}.

Progression Students will conduct experiments in groups, make predictions, and then test those predictions as a class by constructing a 30-foot pendulum. The unit concludes with presentations of the final POW and compilation of the unit portfolio.
