After 30 years of teaching science in MPS (Milwaukee Public Schools), over which time I've gone from formal class training in the use of a slide rule to on-line communication with scientists; from IBM punch cards to flash drives, from ditto machines and copies that students would smell before writing on them to paperless classrooms; I've come to realize that change is good, necessary, and at the very least unavoidable.  With this thought central in my mind I submit the following animations, demonstrations, and links  for your consideration. 

You may already do similar demos but there is nothing wrong with enhancing or expanding on a current practice.  The animations often serve to give a retelling of the story in another voice that may drive a point presented in class home to the student.  If there are other links I should add please submit them via the contact form or use

All links have been individually verified for science content at the High School level as well as science content by this retired science instructor.  This is a tremendous accomplishment given I could be ice fishing right now.  Good Luck in your academic endeavors.  Verification date 4/14/2019
