Lesson Plan Date : 24-06-2005 Teacher : Dr. S S Tong Class : S.4 Location : Heung To Middle School Subject : HKCEE-Physics Topic : Modern transportation Aim : Using contextual themes of car engines, hybrid cars and Magnetic Levitated Train to introduce the concepts of mechanics and magnetism. Objectives : 1. 2. 3. 4. Time 15 minutes 25 minutes Let students appreciate how physics and technology have changed our ways of living. Enhance students' understanding of modern technologies in transportation, including hybrid technology and magnetic levitation. Use contexts of modern transportation to introduce the concepts of electromagnetic induction and its application. Use the context of MagLev train in Shanghai to help students review concepts and solve problems in mechanics.
