PhET Teacher Ideas & Activities: Magnets-Introduction<vcard>BEGIN:vCard\nVERSION:3.0\nFN:Trish Loeblein\nTITLE:\nORG:\nADR; TYPE=WORK,POSTAL,PARCEL:; 29300 Buffalo Park Road; Evergreen; CO; 80439; US\nTEL; TYPE=Office:+(303) 982-5140\nTEL; TYPE=:+\nTEL; TYPE=FAX:+(303) 982-5141\nEMAIL; et al.This web page features an inquiry-based instructional module created specifically for use with the PhET simulation <i>Magnets and Electromagnets</i>. It includes a lesson plan with learning goals, a Power Point presentation designed to introduce secondary students to magnets, and "clicker" elicitation questions. The author, a teacher of high school physics, developed the lesson with these objectives: 1) compare and contrast bar magnets/electromagnets; 2) identify characteristics of electromagnets; 3) relate magnetic field strength to distance; and 4) compare and contrast gravitational field and magnetic field. This resource is part of the PhET project (Physics Education Technology) a growing collection of simulations and curriculum support for teachers and learners of physics, biology, chemistry, and earth science.
