A-level Applied Science/Choosing and Using Materials

About this UnitEdit

From the AQA Specification:

In this unit you will learn about:

  • the different properties of materials such as metals, polymers and ceramics;
  • how scientists define the properties of a material and compare values for different materials;
  • how to measure some of the properties of a material and investigate how they allow the material to be put to a particular use;
  • why different materials behave in different ways;
  • how the internal structure of a material influences the way it behaves;
  • ways in which properties of a material can be modified by altering the structure of the material.

How you will be assessedEdit

In this unit you will be required to complete an external examination of 1½ hours duration. The examination will consist of a series of compulsory short answer questions and will be marked out of 80. The examination may also contain a comprehension exercise.

You will be assessed on your knowledge, understanding and skills relating to choosing and using materials.
