Chemistry (Salters) - As and A2 at Downend School
Emphasis on practical work, good subject combinations are Biology, Physics, Maths, Geography.
Chemistry is the study of the properties and reactions of substances. Practical work is an important element. The course develops an understanding of chemical principles through modern applications of chemistry. The AS course contains five teaching sections (themes).
AS - Three Units
1. Chemistry for Life -
Elements of Life: A study of elements and compounds in the universe, the solar system and the human body.
Developing Fuels: A study of fuels and the contribution that chemists make to the development of better fuels.
2. Chemistry of Natural Resources -
Elements from the Sea: A study of the extraction of halogens from minerals in the sea together with a study of the properties and uses of Group 7 elements and their compounds.
The Atmosphere: A study of important chemical processes occurring in the atmosphere – the ozone layer and the greenhouse effect.
Polymer revolution: A study of the development of addition polymers.
3. Chemistry in Practice -
Competence –carrying out practical. Competence is assessed over a period of time using a minimum of six different practical activities.
Measurement – carrying out quantitative experiments accurately.
Analysis and Evaluation –applying chemical knowledge and processes to unfamiliar situations.
Observation –making and recording valid qualitative observations.
Interpretation – recognising, recalling and showing understanding of chemical knowledge.
A2 - Three Units (plus the AS Units comprising 50% of the total A2 marks)
1. Chemistry of Materials -
What’s in a Medicine? A study of medicines such as aspirin, their development, chemistry and synthesis, illustrating some of the features of the pharmaceutical industry.
The Materials Revolution: A study of condensation polymers and other modern materials.
The Thread of Life: A study of proteins and enzymes, DNA and its use in synthesising proteins.
The Steel Story: An account of the production, properties and uses of steel, with reference to other metals.
2. Chemistry by Design -
Agriculture and Industry: A study of how chemists use industrial processes to benefit mankind and how they contribute towards a safe and efficient food supply.
Colour by Design: A study of chemical basis of colour, pigments, paints and the use of chemistry to provide colours to order.
The Oceans: A study of the role of the oceans in cycling chemicals, including salts and carbon dioxide, and maintaining pH, i.e. the importance of the oceans to life on Earth.
Medicines by Design: An account of the way chemical principles and techniques are used to investigate the effect of chemicals on the body, and to design and make pharmaceutical substances to meet specific needs.
3. Chemistry Individual Investigation -
A single individual investigation for which students are expected to spend about 18 hours in the laboratory. The topic may be taken from any aspect of chemistry. This unit is teacher assessed and externally moderated. You are assessed in eight skill areas: Chemical ideas, Methods, Communication, Observations and Measurements, Analysis and Interpretation, Evaluation and Manipulation, Demand.
AS: GCSE Core and Additional Science at Grade B or above orGCSE Chemistry at Grade B or above
A2: Grade D in AS Chemistry
