Year 7 ILA Homework

Properties of Materials and Recycling

Homework Objective 1To be able to identify standard recycling symbols

GUIDANCE/SUPPORT for homework 1

RecycleRecycling 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.

Properties of materialsDifferent materials have different properties. This means that each material might perform differently when tested or used in the same way.

When you are designing a product, you need to choose a material that has the properties needed by your product.

GUIDANCE/SUPPORT for homework 2

Properties of materialsSome of the questions that you may ask and some of the material properties that you might find related to materials are shown in the table below.
