This is a collection of files I downloaded from the Newton BBS before it disappeared. There are teaching methods, demos, labs and workksheets included. Newton was a great resource, unfortunately I erased most of my files after I printed them. This is definitely worth a look for chemistry and physical science teachers middle school to high school.
