Non-biodegradable materials, like plastic, do not break down easily and accumulate in the environment. They contribute to pollution, harm wildlife, and create long-lasting waste problems, posing a significant environmental challenge.
Biodegradable materials are those that can be broken down by natural processes, like wood, cotton, and paper. They decompose into harmless substances, reducing environmental impact and contributing to sustainability.
Materials are selected based on their properties, such as strength, flexibility, or durability. For example, metal is chosen for tools due to its strength, while plastic is used for containers because it is lightweight.
Metals are strong, hard, and durable. They are good conductors of heat and electricity, making them ideal for tools, machinery, and electrical wiring. Metals are also malleable and can be shaped easily.
Materials are substances used to make objects around us. They can be natural, like wood, or man-made, like plastic. Everything we use daily is made from some kind of material.
Opaque materials do not allow light to pass through them. This occurs because their internal structure scatters or absorbs light, preventing visibility through the material. Examples include wood, metal, and concrete.
Transparency is the property of a material that allows light to pass through it. Materials like glass, clear plastic, and some types of crystal are transparent, allowing us to see through them.
Plastic is lightweight, durable, flexible, and resistant to water and chemicals. It’s also easy to mold into different shapes, making it ideal for a wide range of products, from packaging to electronics.
Plastic is made from petrochemicals through a process called polymerization. This involves combining small molecules, called monomers, into long chains to form polymers, which are then molded into various shapes.
