Ramp walkers are cool toys that "walk" down ramps or in some case are pulled along a flat table by a weight on a string hanging over the edge of a table. Ramp walkers can have 1,2, or 4 moving legs and in some cases have additional moving parts. These two walkers are the first of a series of larger walker built primarily for my amusement.
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.
