Description

Can you make just one of the pendulums move and not the others? I call this my Frequency Amplified Kinesthetic Energy Demonstration (FAKED) device. Perhaps I can do it telepathically, probably not but you can get just one of them to move if you understand the idea of resonance. Simple device, simple demonstration but effective is helping to get the point across.


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.
