KEY STAGE 3  

During key stage 3,  pupils build on their scientific knowledge and understanding and make connections between different areas of science. They use scientific ideas and models to explain phenomena and events, and to understand a range of familiar applications of science. They think about the positive and negative effects of scientific and technological developments on the environment and in other contexts. They take account of others' views and understand why opinions may differ. They do more quantitative work, carrying out investigations on their own and with others. They evaluate their work, in particular the strength of the evidence they and others have collected. They select and use a wide range of reference sources. They communicate clearly what they did and its significance. They learn how scientists work together on presentday scientific developments and about the importance of experimental evidence in supporting scientific ideas.

KEY STAGE 4

During key stage 4,  students learn about a wider range of scientific ideas and consider them in greater depth, laying the foundations for further study. They explore how technological advances relate to the scientific ideas underpinning them. They consider the power and limitations of science in addressing industrial, ethical and environmental issues, and how different groups have different views about the role of science. When they carry out investigations they use a range of approaches and select appropriate reference sources, working on their own and with others. They do more quantitative work and evaluate critically the evidence collected and conclusions drawn. They communicate their ideas clearly and precisely in a variety of ways. They see how scientists work together to develop new ideas, how new theories may, at first, give rise to controversy and how social and cultural contexts may affect the extent to which theories are accepted.
