| Orientation/ Engage (5 minutes) | Set Induction |
Teacher show a box (contain components of electric circuit). Teacher will walk around the class and choose a few pupils to hold the box (but not to open it) and asks them to guess the content of the box. Teacher will also ask the whole class the same question.
Script: Can you guess what is inside the box?
Teacher call upon a few students to take out things from the box and show it to the whole class and ask them if they know the name of the object. |
Expected answer: Food Sweets Rocks

| Eliciting ideas (15 minutes) | Electric circuit: Series circuit and parallel circuit
Get to know various components in a simple electric circuit.
Understanding a series circuit and a parallel circuit.
| Teacher introduces pupils to electric circuit and its components. Teacher will draw symbols on the white board and ask pupils to guess which electric component represented by the symbol.
Components: Bulb, connecting wire, bulb, switch.
Based on the activity where pupils get to know various components in a simple electric circuit, teacher will ask pupils to draw simple series circuit and parallel circuit based on their previous knowledge and imagination. Teacher will ask pupils to volunteer/ pick them randomly for this activity.
Teacher will trigger pupils mind with questions such as:
Scripts: 1. Do you think the arrangement of bulb have effect on the brightness of the bulb? Why?
2. What will happen if one of the bulb is removed? Will it effect on the brightness of the other bulbs? Why? |
Any student who is willing to try answering any question will be given a star as collected points for his/her group.
Pupils will try to draw a simple electric circuit based on the teacher instruction.
To answer the questions, pupils will need to conduct an investigation. | Teaching aids: Laptop Power point slides LCD Screen White board Marker pen Stars
SPS: Observing
Values: Dare to try Being confident and independent Being cooperative
|
| Restructuring ideas (20 minutes)
| Group activities:
Teacher will prepare batteries, bulbs, switch and connecting wires for pupils to build series and parallel circuits.
Pupils take turn to use material prepared by the teacher.
Pupils will build a simple electric circuit.
Pupils draw circuit diagrams of series and parallel circuits.
Pupils will study the relationship between types of circuit and the brightness of a bulb.
When comparing the brightness of the bulbs in series or parallel circuit the number of batteries and bulbs are the same.
Answering worksheet.
Discussing answers for the worksheet.
| Scripts: Form your own group of five.
Group will run activities according to the instructions given in the worksheet.
Each group is required to answer questions in a given worksheet.
Draw basic diagram of simple electric circuit both series and parallel.
|
Pupils are divided into group of five and will take turn to use materials prepared by the teacher and run activities according to the worksheet given.
Each group is required to build electric circuit by following the instruction given.
Working in groups, pupils will answer questions by investigating their electric circuit.
Pupils will still be given stars based on the teacher observation on the group teamwork and noble values. But stars will be deducted if any members of groups happen to be misbehaved.

| Application of ideas (15 minutes) | Group activities:
Inventing “Miner’s lamp”.
Group presentation.
| Teacher will give instruction on what task need to be done by pupils.
Teacher will ask upon the group representative to present the group invention in front of the class.
| Pupils will invent a device called “Miner’s Lamp” using either one of the simple electric circuit that they have learn.
Group representative will present to the class and explain which type of circuit they are using in their invention.
