Conductors vs. Insulators worksheet - Free Printable

Let's solve this science worksheet step by step. The task is to identify whether each object is a conductor (C) or an insulator (I) based on its material and ability to conduct electricity.

---

🔬 Definitions:

- Conductor: A material that allows electricity to flow through it easily (e.g., metals like copper, silver, iron).
- Insulator: A material that resists the flow of electricity (e.g., rubber, plastic, wood, glass, cloth).

Now, let’s analyze each item:

---

1. Towel
- Made of fabric (usually cotton or polyester) → Does not conduct electricity
✔ Answer: I (Insulator)

2. Bicycle tire
- Made of rubber → Rubber is a good insulator
✔ Answer: I (Insulator)

3. Scissors
- Made of metal (steel) → Metals are good conductors
✔ Answer: C (Conductor)

4. Glass cup
- Glass is a non-conductive material → Insulator
✔ Answer: I (Insulator)

5. Basketball
- Typically made of leather or synthetic rubber → Insulating material
✔ Answer: I (Insulator)

6. Coil of copper wire
- Copper is one of the best conductors of electricity
✔ Answer: C (Conductor)

7. Chain (metal links)
- Made of metal (likely steel or iron) → Conducts electricity
✔ Answer: C (Conductor)

8. Baseball bat
- Usually made of wood or aluminum
- If wooden → Insulator
- If aluminum → Conductor
But in most school contexts, if no specific type is shown, assume wooden bat (common in drawings).
✔ Answer: I (Insulator)

9. Eraser
- Made of rubber or plastic → Insulator
✔ Answer: I (Insulator)

10. Balloon
- Made of latex or rubber → Insulator
✔ Answer: I (Insulator)

✔ Final Answers:

1. I
2. I
3. C
4. I
5. I
6. C
7. C
8. I
9. I
10. I
