Let's go through each item in the image and determine whether it is a
conductor or an
insulator, based on scientific principles.
---
🔹 1. PLASTIC
-
Answer: INSULATOR
-
Explanation: Plastic does not allow electricity to flow through it easily. It’s commonly used as insulation for wires because it resists electrical current.
---
🔹 2. COPPER
-
Answer: CONDUCTOR
-
Explanation: Copper is one of the best conductors of electricity. It's widely used in electrical wiring due to its high conductivity.
---
🔹 3. PICKLE
-
Answer: CONDUCTOR
-
Explanation: A pickle contains saltwater (brine), which has dissolved ions (like sodium and chloride). These ions allow electric current to pass through, making it a conductor. This is why pickles can light up a bulb in simple science experiments!
---
🔹 4. FABRIC
-
Answer: INSULATOR
-
Explanation: Most fabrics (like cotton or polyester) are made from materials that do not conduct electricity. They resist the flow of electric current, so they are insulators.
---
🔹 5. WOOD
-
Answer: INSULATOR
-
Explanation: Dry wood is a poor conductor of electricity. It doesn’t have free electrons or ions to carry current, so it acts as an insulator.
---
🔹 6. WATER
-
Answer: CONDUCTOR *(but with clarification)*
-
Explanation: Pure water (distilled) is actually an insulator. However, most water we encounter (tap water, river water, etc.) contains dissolved minerals and impurities (like salts), which make it conductive. So, in everyday contexts,
water is considered a conductor.
---
🔹 7. METAL
-
Answer: CONDUCTOR
-
Explanation: Metals like iron, steel, aluminum, etc., have free electrons that allow electricity to flow easily. All metals are generally good conductors.

✔ Final Answers:
| Item | Correct Answer |
|-----------|--------------------|
| Plastic | INSULATOR |
| Copper | CONDUCTOR |
| Pickle | CONDUCTOR |
| Fabric | INSULATOR |
| Wood | INSULATOR |
| Water | CONDUCTOR |
| Metal | CONDUCTOR |
> ⚠️ Note: The image seems to already highlight some answers in green (correct) and orange (incorrect). But based on science:
> -
Plastic: Should be
INSULATOR (not conductor)
> -
Pickle:
CONDUCTOR ✔️
> -
Water:
CONDUCTOR ✔️ (in real-world conditions)
So, if you're solving this task, ensure you select:
-
PLASTIC → INSULATOR
-
COPPER → CONDUCTOR
-
PICKLE → CONDUCTOR
-
FABRIC → INSULATOR
-
WOOD → INSULATOR
-
WATER → CONDUCTOR
-
METAL → CONDUCTOR
✔ That’s the correct solution!
