High road low road track race, potential-kinetic energy tracks//// Homemade science with Bruce Yeany

Two tracks start at the same height and end at the same height,but... is the shortest distance between both ends the fastest route? How about if we add more hills for it to go up and down ? The 5 sets of tracks shown are good thought provoking exercises in the study of changes from potential to kinetic energy 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.
