Year 7 ILA Homework Properties of Materials and Recycling

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.

Homework Task 1 - Identify the standard recycling symbols shown below from 1 to 6 Products containing materials that can be recycled are often marked to show the material that they are made from. 1 2 3 4 6 5 Recycling Images courtesy of : http: //www. recyclenow. com/why_recycling_matters/recycling_symbols. html http: //www. warwickshire. gov. uk/web/corporate/pages. nsf/Links/513 B 04 AAB 66 E 868 B 80256 EBD 00338 A 6 E Extension Get photographic evidence of SIX plastics products that each have the ONE of the SIX different numbers in the recycling triangle (i. e.

GUIDANCE/SUPPORT for homework 2 Properties of materials Different 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.
