🧲 Conductors and Insulators
Explore how materials conduct or block electrical current in this Grade 6 physics quiz. Learn why some materials like copper allow electricity to flow easily, while others like rubber stop it—and why this matters for keeping us safe every day. **What you'll learn:** - Identify conductors and insulators by their properties - Explain how electron flow determines conductivity - Recognize safe and unsafe uses in household devices - Understand why insulators protect us from electric shock - Know why specific conductors are chosen for wiring
Questions in this quiz
Answers hidden — play to find out.
- Question 1
Which of the following materials is the BEST conductor of electricity?
- Question 2
An insulator is a material that allows electricity to flow through it easily.
- Question 3
Why can conductors like aluminum and copper carry electrical current?
- Question 4
Which material would be SAFEST to use as an insulator on the outside of an electrical cord?
- Question 5
Insulators have electrons that are tightly bound and difficult to move, which is why they block electrical current.
- Question 6
A household light bulb's filament is made of which type of material?
- Question 7
Why is the inside of a power cord made of copper while the outside is made of rubber?
- Question 8
All metals are conductors of electricity.
- Question 9
Which of the following is an unsafe practice when using electrical devices?
- Question 10
What is the main reason electrical wiring in homes uses copper instead of rubber?
- Question 11
An electric shock occurs when electricity flows through your body because your body contains water, which is a conductor.
- Question 12
Which pair correctly matches a material with its electrical property?
- Question 13
In a battery-powered flashlight, which component is made from a conductor to carry electricity?
- Question 14
Insulators are useful in electrical devices only to prevent safety hazards; they serve no other purpose.
- Question 15
Why do electricians wear rubber gloves when working with electrical systems?
