Science Challenge: Magnetism and Electricity

What are the two types of magnetic poles?

• Positive Pole and Negative Pole

• East Pole and West Pole

• Magnetic Field and Magnetic Flux

• North Pole and South Pole

What happens when you bring two like magnetic poles together?

• They repel each other.

• They create a magnetic field together.

• They have no effect on each other.

• They attract each other.

What is the term for the area around a magnet where magnetic forces can be felt?

• magnetic core

• magnetic zone

• magnetic field

• magnetic aura

How do magnetic field lines behave around a magnet?

• Magnetic field lines do not form closed loops.

• Magnetic field lines only emerge from the south pole.

• Magnetic field lines emerge from the north pole, curve around, and enter the south pole, forming closed loops.

• Magnetic field lines travel in straight lines between the poles.

What is the primary purpose of waste management?

• To minimize the impact of waste on health and the environment.

• To encourage littering in public spaces.

• To promote the use of non-biodegradable materials.

• To increase waste production for economic growth.

Name one type of waste that can be recycled.

• food scraps

• metal

• paper

• glass

What is the difference between biodegradable and non-biodegradable waste?

• Biodegradable waste decomposes naturally, while non-biodegradable waste does not.

• Biodegradable waste is made from plastics, while non-biodegradable waste is made from organic materials.

• Biodegradable waste is always toxic, while non-biodegradable waste is safe.

• Non-biodegradable waste can decompose in water, while biodegradable waste cannot.

What is an electric circuit?

• An electric circuit is a closed path through which electric current flows.

• A type of electrical appliance that uses current.

• A device that stores electrical energy.

• A series of batteries connected in parallel.

What are the two main components of a simple electric circuit?

• Power source and load

• Power source and capacitor

• Load and switch

• Power source and resistor

What is the role of a conductor in an electric circuit?

• To convert electric current into mechanical energy.

• To store electric energy for later use.

• The role of a conductor in an electric circuit is to allow the flow of electric current.

• To insulate the electric current from the circuit.
