AS Science in society 1.9
This topic is about the theory of evolution and its significance for biology and for humans’
understanding of their relationship to other species. Darwin’s work is a good example of the
way in which science explanations are developed, using both scientific and cultural ideas.
Students consider some of the evidence that supports the theory.
The objections to the theory are discussed and used to illustrate some differences between
science and other types of knowledge.
The references below to How Science Works (HSW) and to Science Explanations (SE) use
the code letters found in sections 3.6 and 3.7 of the specification. Learning skills for Science
(LSS) activities are integrated into all the AS topics. These represent an alternative or
additional approach to some topics, emphasising the development of skills. They can be used
flexibly for class or homework activities depending on time available.
