Homemade Science Demonstrations with Bruce Yeany

Welcome to my science channel, here are a few examples of some of the interesting materials and activities that I've posted over the last 5 years . Over 170 videos of demonstrations and activities that I've found interesting and helpful as a middle school physical science teacher for 41 years. I've retired last year but still have a lot more information that I'd like to share with everyone that has an interest in science.
