1. Year 7 ILA Homework Properties of Materials and Recycling

2. Homework Objective 1 To be able to identify standard recycling symbols GUIDANCE/SUPPORT for homework 1 Recycle Recycling means that you take the material used for a part, break it down or melt it and use it to make a new part. Recycling can be carried out for metals and many different types of wood, plastics, card and paper. It is easiest to recycle products that are made from only one material. Unfortunately, many products are made up of lots of different parts and materials, which means that they need to be taken apart to allow recycling. As a result, it can sometimes cost more to recycle than it would to make new material.
