Electricity and Magnetism

Lesson Plan of Electricity and Magnetism

General Science Grade IV

STUDENT ‘S LEARNING OUTCOME

  • Make a simple electric circuit.
  • Distinguish between open and close electric circuit.

INFORMAATION FOR TEACHER

  • Then battery cell, bulb and switch are connected with the help of wires, electric current starts flowing through them. Such a connection of different devices is called   ELECTRIC CIRCUIT.

Open & Close Circuit

  • When circuit is open when the switch is OFF.
  • When circuit is close when the switch is   ON.

                                 MATERIAL REQUIRED

Battery cell, Connecting wires, Torch bulb with holder, Switch, sheet of white paper

   Worm up activity 

  • Ask what do we do when it gets dark.
  • How do we turn on a bulb?
  • what happens when we press the switch on?
  • Inform the students that while entering in the home at night, we press a switch and the whole room is lighted. While going out we turn the switch OFF.
  • What makes the bulb light up? When turning the switch ON, do we start using electricity?
  • Do we also use electricity when we turn off the switch? (No)
  • Do you know what is an electric circuit? Let us perform the following activity to find out about it.

                                                                         DEVELOPMENT

Activity: 1

  • Give each group a set of materials [Battery cell, connecting wires, switch and bulb].
  • Ask them to light the bulb by constructing a circuit with the material provided.
  • Guide the students if they feel any difficulty.
  • Ask the students to close the switch. Does the bulb glow?
  • What passes through the wires to make the bulb glow?
  • Ask the students to open the switch. What happens to the bulb?
  • Ask, why does the bulb not glow when the switch is open?
  • Now draw a diagram of electric circuit on the board.
  • Ask some questions to make the concept of students clear.

Electricity & Magtesim

   →   What made the bulb glow?

   →   What is the use of battery? [Battery make the bulb glow].

   →   What is a close circuit?

   →   What is an open circuit?

   →   Does the current flow when the circuit is open?

   →   Does the current flow when the circuit is closed?

                                                                                ASSESSMENT

  • Make a chart or write down on blackboard for the following questions. Display it on the wall at the end of lesson and will ask the questions verbally.

Electricity & Magtesim

   →   When does a current flow in the circuit?

   →   What is the basic requirement for the flow of current in the circuit?

   →   Why does the bulb not glow when the switch is open?

   →   Does the current flow in the circuit if the switch is open.

   →   What is the use of the battery?

   →   What is the function of the connecting wire in the circuit?

                                                                FOLLOW UP / HOME WORK

  • Prepare a list of electric appliances used in your home.
  • In which states are their circuits open or close?

The caricature is tasteful, your authored material stylish. however, you command get bought an nervousness over that you wish be turning in the following. ill certainly come further previously once more since exactly the similar nearly a lot continuously within case you shield this increase.
