What you’ll learn

Materials All AroundUnderstand that objects are made from materials and name common ones.The stuff an object is made from is its material. Common materials include wood, metal, plastic, glass, and fabric, and each looks and feels different. The same object, like a cup, can be made from several materials.
What Materials Are LikeDescribe material properties such as see-through, waterproof, hard, and bendy.Every material has properties, which are ways it behaves. Glass is see-through, rubber and plastic are waterproof, and materials can be hard, soft, or bendy. Comparing properties helps us understand what each material is good at.
The Right Material for the JobMatch materials to jobs based on their properties and explain the choices.People choose materials by thinking about the job an object must do. See-through glass suits windows, waterproof rubber suits boots, and strong wood suits tables. Picking the material with the right properties makes objects work well.
