WebIt will give their examination some focus if they are required to compile lists, say, hard or soft, or solid, liquid or gas. If students do not seem to be thinking about why the materials differ ask a few leading questions such as "Why might solid iron be different from aluminium?" Or you could develop a game of 20 questions to identify a material. Web1 jun. 2024 · Aluminum metal will readily react with water at room temperature to form aluminum hydroxide and hydrogen. That reaction doesn’t typically take place because a layer of aluminum oxide naturally coats the raw metal, preventing it from coming directly into contact with water.
