    3.  Identify the component that connect other components together.

                                    (i)  Wire                                  (ii)  Switch

                                    (iii)  Bulb                                (iv)  Battery

                         4.  Which part of the circuit lights up when the connection is complete?

                                    (i)  Battery                               (ii)  Switch

                                    (iii)  Bulb                                (iv)  Wire

                      B.  Write ‘T’ for true and ‘F’ for false.

                         1.  The Circuit Lab is a virtual place where you can safely explore
                             and create circuits.

                         2.  In a virtual lab, it is possible to get an electric shock while testing

                             a circuit.

                         3.  In a complete circuit, electricity cannot flow through wires.

                         4.  Material like paperclips can be used to test if they conduct electricity.

                      C. Fill in the blanks using the given hints:
                                                                                                              Hints
                         1.  The                  is an online virtual lab.                                Virtual tools

                         2.  The                  show you how the circuit behaves in real-                 Electricity
                             time.                                                                           PhET lab
                                                                                                               Bulb

                         3.  A                  acts as a load, converting electrical energy
                             to light.

                         4.  When the circuit is complete, the Light Bulb lights up, demonstrating that

                                             is flowing through the wires.

                      COMPETENCY-BASED QUESTIONS

                      1.  Your friend wants to make a bulb light up but does not know the components
                         needed. Tell him the circuit components he will need to make the bulb light up.

                      2.  Rohan is testing a circuit with a switch. When the switch is turned on, the bulb

                         lights up. What role does the switch play in the circuit?
