Stringless pendulums/// Homemade Science with Bruce Yeany

Here an idea for showing how or why a pendulum's movement becomes faster or slower as it's length is changed. The period is a function of length and as the length changes, so does it's path.

Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylvania. I am currently in my 38th year of teaching. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself.. I also share and show some of these ideas at workshops, science conferences, or inservice presentations.
