Don't touch the power socket with wet hands, etc
Basic components to make a simple circuit
Cell, wire and bulb
In which circuit will the bulb or bulbs glow dimmest?
A. a simple circuit with two bulbs and two batteries
B. a simple circuit with two bulbs and one battery
a simple circuit with two bulbs and one battery
What is the source of electricity called?
Mention one electrical appliance that uses main electricity.
Computer, fridge, etc
Name two different ways to be safe while using electricity.
Don't use broken wires, don't plug too many plugs into a power socket, etc
What is a circuit?
It is a path for electricity to flow
In which circuit will the bulb or bulbs glow brightest?
A. a simple circuit with one bulb and one battery
B. a simple circuit with two bulbs and one battery
C. a simple circuit with one bulb and two batteries
a simple circuit with one bulb and two batteries
Mention two electrical appliances that use batteries in the classroom.
Clock, computer mouse, Ac remote, projector remote, timer
Mention two electrical appliances that use main electricity and batteries
Laptop, iPad, tablet, phone
Why should we not stick a metal fork into a power socket?
Metal can help electricity to flow so we can get electric shock.
What is the function of the wire?
To connect/allow the electricity to flow
Is it true?
The phone only uses batteries. Explain your answer.
False, because phones use batteries and main electricity
What is the difference between a cell and a battery?
A cell is a single unit, battery a collection of cell
What is one reason why electricity is important to how we live today?
Washing machine for washing the dirty clothes, light to light up our space, etc
What should you do before changing a lightbulb in your home?
Turn off the light/power outlet/switch.
What is the function of the cell/batteries?
Power Source
Why should we not touch electric plugs with wet hands?
We can get electric shock, water is good for electricity to flow
Oliver builds a simple circuit using wires and a bulb. He connects all the components. Will his circuit work? Explain your answer.
No, because there is missing component which is battery
Mia builds a circuit with some components: wires, two bulbs, and one cell. Predict what will happen to the bulbs.
The bulbs will light up dimmer
Why do we stay away from lakes during a storm?
Water is good for electricity to flow through. Lightning may strike there.
What is the function of a light bulb?
To check whether the electricity is flowing or not
Mia builds a circuit with some components: wires, three bulbs, and one cell. Predict what will happen to the bulbs and explain the reason.
The bulbs will light up dimmer. Mia only uses one cell so it doesn't have enough power or the bulbs will not light up since it doesn't have enough power.
Mia builds a circuit with some components: wires, two bulbs, and one cell. The bulbs light up dimmer.
Mia removes one bulb and adds one cell. Predict what will happen to the bulb now.
The bulb will light up brighter than before.
Mia builds a circuit with some components: wires, one bulb, and two batteries. The bulb lights up brightly. Next, Mia adds 2 more bulbs. Predict what will happen to the bulbs.
The bulbs will light up dimmer
