A group of students is attempting to determine the mathematical relationship between
the length of a pendulum and its period (one complete swing of a pendulum). The
group makes a simple pendulum from string and washers and then suspends it from
the ceiling. They record the pendulum’s period for each of 12 string lengths.*
