Galileo's Inertia track////Homemade Science with Bruce Yeany

Both sides of the track are the same height, one side is 3 times longer than the other side. If I release the ball from one side can it roll off of the other side? This track was based on a series of tracks that is said to have led Galileo to the idea of inertia.


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.
