A. It helps teachers to teach and pupils to learn the concepts of the electric circuit.
It is useful for pupils to
i. Identify components in an electric circuit i.e., dry cell, bulb and switch.
ii. Explain functions of the components in a complete electric circuit.
iii. Build a complete electric circuit using dry cell, bulb, switch and connecting wire
iv. Predict why the bulb does not light up in a circuit.
v. Record whether a bulb will light up when the switch is replaced with other objects or materials by carrying out investigations.
vi. Make generalization of objects that can light up a bulb in a circuit are conductors and objects that cannot light up a bulb are insulators.
B. Gives pupils opportunities to set up simple electric circuits, investigate and problem solve why a circuit is not complete.
C. Enables pupils to be creative in setting up and extending circuits to include other components like motor, buzzer and LEDs.
