Making a One Second Timer 

written by Jim Nelson and Jane Nelson

This lab activity has students create a pendulum with a one second period.  Students must explore the importance of physical properties, such as length of the string and mass of the bob, to determine what they affect the period. This is a part of a PTRA manual on Kinematics and Motion by Jim and Jane Nelson.
