Activity 1 – Topic of lesson
Procedure
It starts with a brainstorming activity, then the teacher asks Ss to
complete worksheet1. The teacher introduce the topic by the
multimedial presentation with the title ”Electricity”.
The activity ends with a discussion about the content:
 Electricity and electric circuits are all around us.
 Discuss examples of electric circuits and electricity.
Approx. time
2 hour
Level
A2
Learning outcomes
The Ss learn:
 to define electricity as the physical phenomena associated with
the flow or movement of electric charge.
 to define electric charge as a fundamental property of some
subatomic particles.
 to explain that a conductor is something which freely allows the
motion of electric charge and an insulator is the opposite; it
greatly resists the flow of charge.
 to explain how electric current flows in a circuit.
 to define voltage as the electric potential between two points.
 the SI unit for voltage and current intensity.
 some new words regarding the topic
Indicators
 Active participation in discussion
 Knowledge and use of keywords

Activity 2 – The electric circuit
Procedure
The Ss are divided into groups for three or four students and make an
electric circuit comprising a battery, an electric resistance and a bulb
(Electric circuit activity).
The Ss analyze and summarize the results of your experiment, they list
any questions you still have about your experiment and they describe
what they have learned about electric circuits from the worksheets.

Materials
The Ss learn:
 to define resistance as a physical property which describes how
well electric current flows in a material
 the SI unit for resistance
 to define the electric circuit as a connection of two or more
components to form a closed loop
 the closed loop is necessary to allow the electric current to flow
from one point of the voltage source to the other
 learn some new words regarding the topic
 to wire a basic circuit
 application of new knowledge
 Interaction in group using English
 Sharing of knowledge with others
