      Definition of a lens

      Lenses

      A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

      What is in a lens?

      Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

      Who can create a lens?

      Any individual Connexions member, a community, or a respected organization.

Measuring and Predicting

Module by: Interactive Mathematics Program

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=cxy=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.
