Pendulum Lab

Learning fit

Labels show who asserted each claim.

A pendulum measurement lab for ages 10-15 whose period follows the real formula T = 2pi sqrt(L/g) with g = 9.8. Swing Lab offers length (0.25-2 m), bob mass (which changes nothing), and release-angle controls, plus a stopwatch with a Count 10 Swings helper that compares measured period against the formula. The Big Question guides three one-variable experiments to the reveal that only length changes the period, which is how grandfather clocks are adjusted. Galileo's Clock tells the pulse-timing legend, Huygens' 1656 clock, and the 1 m seconds pendulum.
