Science: Insulator or conductor? | Worksheet | PrimaryLeap.co.uk - Free Printable

Task Explanation:

The task requires identifying whether each object in the image is an insulator or a conductor of electricity.

- Conductors: Materials that allow electric current to pass through them easily. Examples include metals and some liquids (like saltwater).
- Insulators: Materials that do not allow electric current to pass through them easily. Examples include rubber, plastic, and wood.

Solution:

Let's analyze each image one by one:

1. Fleece jacket:
- Made of fabric (usually synthetic or wool).
- Insulator because fabrics are poor conductors of electricity.

2. Pan with eggs:
- The pan itself is likely made of metal (e.g., stainless steel or aluminum).
- Conductor because metals are good conductors of electricity.

3. Wooden door:
- Made primarily of wood.
- Insulator because wood does not conduct electricity well.

4. Hat:
- Made of fabric (wool, cotton, or synthetic materials).
- Insulator because fabrics are poor conductors of electricity.

5. Metal radiator:
- Made of metal (often cast iron or aluminum).
- Conductor because metals are good conductors of electricity.

6. Sweatshirt:
- Made of fabric (cotton, polyester, etc.).
- Insulator because fabrics are poor conductors of electricity.

7. Sink:
- Typically made of ceramic or porcelain.
- Insulator because ceramics are poor conductors of electricity.

8. Gloves:
- Made of fabric or leather.
- Insulator because both fabrics and leather are poor conductors of electricity.

9. Light bulb:
- The filament inside the bulb is made of tungsten, which is a metal. However, the bulb as a whole includes glass and other insulating materials.
- Conductor for the filament but overall, the bulb is used as an insulator in circuits.

10. Blanket:
- Made of fabric (wool, cotton, or synthetic materials).
- Insulator because fabrics are poor conductors of electricity.

11. Slippers:
- Made of fabric or rubber.
- Insulator because both fabrics and rubber are poor conductors of electricity.

12. Teapot:
- Typically made of ceramic or metal. If it’s ceramic, it’s an insulator; if it’s metal, it’s a conductor.
- Assuming it’s ceramic: Insulator.

Final Answers:

1. Fleece jacket: Insulator
2. Pan with eggs: Conductor
3. Wooden door: Insulator
4. Hat: Insulator
5. Metal radiator: Conductor
6. Sweatshirt: Insulator
7. Sink: Insulator
8. Gloves: Insulator
9. Light bulb: Conductor (filament)
10. Blanket: Insulator
11. Slippers: Insulator
12. Teapot: Insulator
