In recent years scientific knowledge and understanding has increased, resulting in the introduction of new materials, drugs and technologies. Many of these are beneficial to us but some have implications on society and the environment.
The Earth provides us with the resources necessary for our continued existence. Scientists play a vital role in furthering our understanding of how resources can be removed from the Earth and used for our benefit whilst ensuring sustainability.
Scientists such as research chemists, materials scientists, environmental scientists and polymer scientists all work to try to produce new products and minimise their impact on the environment. They also realise that the home environment needs to be monitored in order to maintain our health and wellbeing.
This unit is assessed by a one-hour written paper, which is worth 25% of the overall marks for the specification.
Application of knowledge and understanding gained in discussing, evaluating and suggesting implications of data and evidence is also assessed in the written paper. Areas that could be covered are highlighted at the end of each context.
