During KS4 Chemistry, students learn about the way science and scientists work within society. They consider the relationships between data, evidence, theories and explanations, and develop their practical, problem-solving and enquiry skills, working individually and in groups. They evaluate enquiry methods and conclusions both qualitatively and quantitatively, and communicate their ideas with clarity and precision. All students develop their ability to relate their understanding of science to their own and others’ decisions about lifestyles, and to scientific and technological developments in society. Students also develop their understanding and skills in ways that provide the basis for further studies in science and related areas.
Chemical and material behaviour
- Chemical change takes place by the rearrangement of atoms in substances
- There are patterns in the chemical reactions between substances
- New materials are made from natural resources by chemical reactions
- The properties of a material determine its uses
Earth and Environment
- The surface and the atmosphere of the Earth have changed since the Earth’s origin and are changing at present
- The effects of human activity on the environment can be assessed using living and non-living indicators
Structure and bonding
- The outer electrons of atoms are involved in chemical reactions.
- The structure and properties of a substance are strongly dependent on the nature of the bonding which results from the forces between the electrons and nuclei of atoms.
- Raw materials are converted into new and useful substances by chemical reactions.
- The theoretical yield of a chemical reaction can be calculated.
