====== Density and Buoyancy Demonstrations ===== Density is a measure of how much mass is contained in a given volume, and buoyancy explains why objects float or sink. This category explores the principles that connect mass, volume, and displacement. Understanding density and buoyancy helps explain natural phenomena and practical applications in science and engineering.\\ ---- struct table ---- schema: demo cols: page, materials, difficulty, safety, summary header: "Demonstration", "Materials", "Difficulty", "Safety", "Summary" filter: categories~Density and Buoyancy filter: page~demonstrations:% sort: title csv: 0 ---- **Materials**\\ ★☆☆ Easy to get from supermarket or hardware store\\ ★★☆ Available in most school laboratories or specialist stores\\ ★★★ Requires materials not commonly found in school laboratories\\ **Difficulty**\\ ★☆☆ Can be easily done by most teenagers\\ ★★☆ Available in most school laboratories or specialist stores\\ ★★★ Requires a more experienced teacher\\ **Safety**\\ ★☆☆ Minimal safety procedures required\\ ★★☆ Some safety precautions required to perform safely\\ ★★★ Only to be attempted with adequate safety procedures and trained staff\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\
