Welcome to Dr. Tollefson's Science site!
Dr. Tollefson graduated from the University of Wisconsin (BS) and the University of Illinois (Ph.D.) He has worked in scientific laboratories for over 20 years before coming to Nashoba. The importance of laboratory work will be stressed as we explore the world of science this year. The scientific method will be at the center of the curriculum with the goal of long term memory of physics concepts to help students with their future pursuits. We will construct scientific models to help explain and predict the world around us. Welcome!
