Lesson content
What is Plastic?
Plastic is a synthetic material made from polymers. It’s lightweight, durable, and easily molded into different shapes. We use plastic in many things, like bottles, bags, toys, and furniture. it’s a synthetic material commonly used because of its versatility.
what is Rubber?
Rubber is a material, either natural or synthetic, that’s stretchy. It’s used to make things like tires, erasers, and shoe soles. we also find it in hoses, belts, and gloves.
Types of Materials
Plastic
Many different kinds of plastic exist, each with its own special qualities. The following are examples:
Rubber
