Insulator
An insulator is a material that does not easily allow the flow of electricity or heat through it. This is because insulators have tightly bound electrons that do not move easily, which prevents the flow of electricity or heat.
Properties of Insulators
Insulators have the following properties:
- High resistance to the flow of electricity
- Poor conductors of heat
- Do not easily allow the movement of electrons
- Examples of insulators include rubber, plastic, glass, and wood
Applications of Insulators
Insulators have various applications in everyday life and technology:
- Insulating materials are used to cover electrical wires to prevent the flow of electricity to unwanted places
- Thermal insulators are used in building materials to maintain indoor temperatures
- Insulating gloves and mats are used by electricians to protect themselves from electric shocks
Study Guide
Here are some key points to remember about insulators:
- An insulator is a material that does not allow the flow of electricity or heat easily
- Insulators have tightly bound electrons that do not move easily
- Examples of insulators include rubber, plastic, glass, and wood
- Insulators have applications in electrical insulation and thermal insulation

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
