​Assalamuálaikum..

Good Morning Class..

​

How are you all today? Are you ready to learn..

​Today we are not going to learnt much but we will revise on some of the things that we learnt for the previous lessons:

​

Electrical Circuits

(Murid2 bule salin notes di bawah ini ke dalam buku atau kertas) You can copy this down in a book or paper)​

What you should know and remember:

1) We need batteries, bulbs and wires to make an electric circuit.

2) Batteries are energy source for the electric circuit.

3) Wires are use as connectors to connect all the parts.

4) We use copper wires because copper is a good conductor of electricity.

5) Good conductor of electricity means electricity can pass through it.

6) Wires are covered with plastic. So that its safe for us to touch it.

7) Plastic is a bad conductor of eletricity or called insulator because electricity

cannot pass through it.

​

​

8) When a circuit is closed the battery/batteries will light up.

9) When a circuit is open the battery/batteries will not light up.

10) Almost all the electric things we use has a circuit inside.

11) Electric circuits that use main electricity are like Television, fridge, oven and

others.

12) We need the electricity in Television so we can watch television.

13) We need the electricity in oven or microwave so we can cook or heat up our

food.

14) Some electric circuits use batteries or dry cell like remote control, watch, clock

and others.

15) Electricity is important in our everyday life.

​Teacher hope you understand and will remember our lesson for today and everyday. Next you will do the exercise given using liveworksheets.

​

Good Luck... :)
