H. Learning Activity :
Teacher’s Activities | Student’s Activities | Time Allocation |
Opening : - Greeting and Prayer - Cheeking attendance | Students prays and answering if called by teacher. | 2 minutes |
Main Activities : A. Eksploration 1.Motivation and apperception - The children had never heard of an electric bell? - There is a cause electric bell can ring? 2. Prerequisite knowledge - An electric current flowing a conductor will cause what? B. Elaboration 1. Teachers guide learners in group formation 2. The teacher informs that the electric current flowing through a conductor will cause a magnetic field 3. Presenting information brought current carrying conductors are in place in a magnetic field will experience a Lorentz force 4. Each working group worksheets are available 5. In the group of students make tentative conclusions and communicate the group members C.Confirmation 1. Teachers test student about ring bells of magnetism 2. Teachers gives students change for ask about magnetism and lorents force | - Listen to teacher explanation seriously - Student asks on teacher about magnetism fild and lorents force | 10 inutes |
Closing : 1.The teacher gives the Lorentz force exercises 2. The teacher gives a homework exercise | Summarizing about magnetism fild and lorents force | 3 minutes |
