The purpose of collecting different materials like paper, wood, and metal is to observe and compare their physical properties, such as shine, texture, and color, which helps in understanding their characteristics and grouping them based on similarities.

A material shines when light falls on it by observing if it reflects light, creating a glossy or metallic appearance. Shiny materials, like metals, will visibly reflect light, unlike dull or matte surfaces.

Sports balls can be grouped based on properties like size, color, texture, and bounce. For instance, balls used in games like tennis and cricket may be grouped together based on their smaller size compared to larger balls used in football and basketball. They can also be categorized by color, such aRead more
Sports balls can be grouped based on properties like size, color, texture, and bounce. For instance, balls used in games like tennis and cricket may be grouped together based on their smaller size compared to larger balls used in football and basketball. They can also be categorized by color, such as white cricket balls or yellow tennis balls, and by texture, such as the smooth surface of a basketball versus the stitched surface of a baseball.
Some metals lose their lustre over time due to oxidation, tarnishing, or corrosion. Exposure to air, moisture, and environmental pollutants causes surface reactions that dull the metal's shine. For instance, iron rusts, and silver tarnishes, reducing their reflective qualities.

Non-lustrous materials include wood, rubber, and most ceramics. These materials typically have a matte or dull surface that does not reflect light well, resulting in a non-shiny, non-glossy appearance.
