Candy is made from sugar, and sugar comes from a plant. Your sweater might be made of sheep s wool, and many bridges are made out of stones. We make things by taking some material directly from nature. Other things are made by artificial materials. Things we use every day are made from all kinds of material wood, paper, metal, glass, wool, cement, and many other materials. But we must always use the right material for each thing we make. Can you imagine the problem we would have if we tried to make this book out of metal? It wouldn t be a very useful book!
