DEFINITIONS:
Karachi Public School Battery:
Malir campus A battery or cell is an energy source that can store electricity.
Grade IV Cambridge Buzzer:
Science A buzzer is a component in a circuit that will make noise.
Mid Term 2022-2023 Definitions/Key words/Glossary: Circuit:
A circuit is a complete circular path through which electricity flows .

Okay, let's review what we've learned about electricity in this lesson. Electricity is The part of circuit is called a component.
everywhere and can be generated by making electrons move around each other. Conductor:
Friction between objects can generate electricity by moving the electrons. Electricity A substance or material that allows electricity to flow through them
travels from power plants through wires, called power lines, into our homes to give us easily.
power. We learned that things that allow easy travel of electricity are called
Electricity:
conductors. We also learned how electricity comes in two forms:
Electricity is the presence and flow of electric charge.
Static electricity, which doesn't move from one place to another and stays in the place
it was created.
Current electricity is when an electrical charge is given a path to move through. QUESTION AND ANSWERS
Q.1: Why and when should we use batteries instead of main
What is electricity? electricity? Ans: Main electricity can be dangerous when
Electricity is an energy. This energy can be used to power electrical items such as performing experiments bystudents whereas batteries are safe to
toasters, kettles, cookers, televisions and computer tablets. Electrical energy is caused use.
by electrons (the particles in atoms) moving about to make a current. Q.2: What are some of the uses of batteries?
With Examples Ans: A battery can store electricity. We use batteries in different
People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances,watches, mobiles and vehicles.
appliances, computers, electronics, machinery, and public transportation systems. Q.3: What is a simple series circuit?
5 Creative Ways to Teach Basic Electricity Ans: If a single bulb is connected with a wire and battery
together lightsup, this kind of circuit is known as simple series

Ans: Conductors:
5.Bridge the Gap with Practical Real-World Examples. The materials which allow electricity to pass through them are
calledconductors.
Insulators:
The materials that do not allow current to pass through them at all
are called insulators.
Q.5: What will happen if the circuit is complete?
Ans: If the circuit is complete the electricity will flow through it to complete
the circuit and the bulb will light up.
Q.6: What is the use of a buzzer?
Ans: When a buzzer is added to a circuit it makes a noise to indicate the circuit
is complete.
Q.7: How can we find a fault in a series circuit?
Ans: We can connect each component of the series circuit with a test circuit to
find fault in the faulty component and replace it.
Q.8: Why does the fairy light bulb stop working if one of the bulb stops
working?
Ans: Fairy lights are joined in a very long circuits, if one of the bulb stops
working the circuits get broken and electricity cannot pass through it so none
of the bulb will work.
Q9. Why do we use a switch?
Ans: We use a switch to control the flow of electricity.
Q10: How could you make a bulb in a circuit brighter?
Ans: If we add more batteries in the circuit the bulb will get brighter.
Q11: What happens when a circuit is broken?
Ans: When a circuit is broken it creates a gap between the components of the
circuit, the circuit becomes incomplete and current does not flow through it.
Q12: Why are wires insulated?
Ans: Wires are insulated to stop the electricity flowing into the body when
touched.
