Bulgaria Vtoro OU „ Nikola I . Vapcarov “
Subject ( s ) Topic Aims of the lesson
Physics Sequential and parallel connection of electrical circuits 1 ) Students will create wire diagrams for their electric buildings ; 2 ) students know the requirements for a circuit ( closed , conducting loop & voltage source ); 3 ) students can create circuits with resistors in parallel and series , and can describe how adding additional resistors affects the voltage , current , and effective resistance of that particular circuit configuration ; 4 ) students know and can apply Ohm ’ s Law for circuits ( U = IR )
Age of students 13-14 Time Methods
40 minutes Interactive methods in the teaching process : using a virtual lab , project-based task , experiment
Teaching resources
Computers , presentation materials , students work in a virtual lab in a computer room
Activities 1 . Students are asked to respond these questions : a ) Do you think the electrical appliances in your house / apartment are in series or in parallel with each other ? How do you know ? b ) How do you think electricians know how to correctly install lights and electrical outlets in a building ? 2 . Teacher provides support ( as needed ) in guiding students towards creating the correct wire diagram for the electric building ( One switch controls a single lamp , one switch controls two lamps in series , and one switch controls three lamps in series , with all three branches in parallel with each other , connected to voltage source ). 3 . Pupils test the schemas in the site for physical simulations . 4 . Students submit wire diagrams to “ The City Inspector ” ( the teacher ) for approval . Homework / with the help of parents /: Students create a design poster , selling their house to the public , explaining the purpose of each roomand the theme of the entire building . The design of the poster must include an approved electrical circuit and floor plan , facade and drawings of the house
Differentiation
Assessment , evaluation
Working in a group of two . When grouping is used , the difference between the members of the group
is used : drawing , linking the chains , and presenting the result By sending the result , each participant sends a emoticon illustrating the attitude towards the subject
9 and tasks . The teacher assesses the diagrams and performance of students and homework with an
average of qualitative and quantitative assessment
