====== Catalysts Demonstrations ===== Catalysts are substances that affect the speed of a chemical reaction without being consumed in the process. This category explores how catalysts work, why they are important in both natural and industrial settings, and how they connect to ideas about energy and reaction rates. Understanding catalysts helps explain efficiency in chemical and biological systems.\\ ---- struct table ---- schema: demo cols: page, materials, difficulty, safety, summary header: "Demonstration", "Materials", "Difficulty", "Safety", "Summary" filter: categories~Catalysts 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\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\
