Metals - materials characterized by their luster, malleability, ductility, and good electrical and thermal conductivity. They are often used in construction, machinery, electronics, and transportation due to their strength and durability., Polymers - large molecules composed of repeating units called monomers. They can be natural (e.g., cellulose, rubber) or synthetic (e.g., plastics, synthetic fibers). Polymers have diverse properties and are used in a wide range of applications, including packaging, textiles, automotive parts, and medical devices., Ceramics - inorganic, non-metallic materials typically made from clay, silica, or other minerals, which are hardened by firing at high temperatures. They are known for their hardness, brittleness, and heat resistance, making them suitable for applications such as pottery, tiles, bricks, and advanced ceramics used in electronics and aerospace industries., Wood - a natural material derived from the stems and branches of trees. It is valued for its strength, versatility, and aesthetic appeal. Wood is used in construction, furniture making, paper production, and various decorative and artistic applications., Composites - materials made by combining two or more different types of materials to create a new material with enhanced properties., Glass - an amorphous, transparent or translucent material made primarily from silica. It is known for its hardness, smoothness, and optical properties. Glass is used in windows, bottles, lenses, optical fibers, and electronic displays, among other applications., Natural Fibers - materials derived from plants (e.g., cotton, flax, hemp) or animals (e.g., wool, silk). They are valued for their comfort, breathability, and biodegradability. Natural fibers are used in textiles, ropes, papermaking, and composite materials.,
