At Key Stage 3, students have to learn new skills as well as new concepts. We can discuss the results of experiments, the theoretical aspects, assist with analysis, help students improve their mathematical skills and help students improve the quality and organisation of their written answers.

The current KS3 Science National Curriculum states the following aims:

  • develop scientific knowledge and conceptual understanding through the specific disciplines of biology, chemistry and physics

  • develop an understanding of the nature, processes and methods of science through different types of science enquiries that help them to answer scientific questions about the world around them

  • are equipped with the scientific knowledge required to understand the uses and implications of science, today and for the future

It is split into 4 areas; 1 skill-based area and the 3 sciences:
  1. Working Scientifically

  • Adopting the attitudes of a scientist

  • Developing experimental skills and carrying out investigations

  • Developing the skills of analysis and interpretation of results

  • Developing the use of mathematics and SI units of measurement in a scientific setting.

  1. Biology

  • Understanding the ways cells function within the body.

  • Understanding the structure and functions of parts of the skeletal and muscular systems.

  • Understanding how living things digest and/or absorb nutrients.

  • Understanding the processes and significance of gas exchange in plants and animals.

  • Understanding how reproduction occurs in both plants and animals.

  • Understanding how recreational drugs affect the body.

  • Understanding the process of photosynthesis and the adaptations required for the process.

  • Understanding respirations in cells.

  • Understanding the different relationships between organisms, other organisms and the environment.

  • Understanding how characteristics are inherited and passed down, the importance of biodiversity and the role that natural selection takes.

  1. Chemistry

  • Understanding states of matter and changes in state.

  • Understanding the atomic model, the difference between elements, compounds and mixtures.

  • Understanding the use of symbols in formulae and conservation of mass in state and chemical reactions.

  • Understanding the difference between pure and impure substances, and, in addition, how these pure substances can be separated from impure ones using techniques.

  • Understanding various types of chemical reactions such as neutralisation, combustion, oxidation, displacement, acids and alkalis, and acids and metals. Furthermore, understanding how catalysts speed up reactions.

  • Understanding the energy changes involved when substances change state and the difference between exothermic and endothermic reactions.

  • Understanding the periodic table and the properties that can be associated with different groups. 

  • Understanding the differences between metals and nonmetals.

  • Understanding the properties of various materials.

  • Understanding the Earth’s structure, the various types of rock formations, finite resources, recycling, the carbon cycle, the composition of the atmosphere and the role of humans in climate change.

  1. Physics

  • Understanding energy and how the costs of energy are calculated in a domestic setting.

  • Understanding energy changes and transfers.

  • Understanding how changes in energy can be physically observed.

  • Learning how to describe motion in more detail.

  • Understanding forces and learning how to represent them in diagrams, how they relate to the ideas of work done and energy requirements. 

  • Understanding the concept of gravity.

  • Understanding pressure in fluids and in the atmosphere.

  • Understanding balancing and opposing forces.

  • Understanding how forces relate to motion.

  • Understanding different types of waves. Emphasis is placed upon light and sound.

  • Understanding electricity, including concepts such as current, series and parallel circuits, potential difference (voltage), ohms etc.

  • Understanding the difference between insulators and conductors.

  • Understanding static electricity.

  • Understanding concepts of magnetism and polarity. 

  • Understanding in a limited sense how D.C. motors operate.

  • Understanding physical changes: melting, freezing,  evaporation, sublimation, condensation, and dissolving.

  • Understanding the particle model.

  • Understanding how energy can be stored.

  • Understand the basic concepts of space physics.

The KS3 science curriculum is much more theoretical than the KS2 curriculum. It is a very important stepping stone into GCSE science as it provides the foundation to these exams as well as the transition between the big jump from KS2 to GCSE. KS3 science tuition gets the learner ready for KS4!

In our experience, students tend to enjoy the science that they learn at Primary School, but as they enter secondary school, they are introduced to the more theoretical aspects of science.

Often, students who struggle to fully grasp the theoretical aspects, and therefore can sometimes lose interest in the sciences. This loss of interest can lead to a loss in competency and confidence.

How Redbridge Tuition can help

At Redbridge Tuition, our aim is to help our students understand the theoretical aspects and assist them in understanding how science underpins their own lives and existence.

If a student is able to master the concepts introduced at Key Stage 3, then greater success usually follows at GCSE.

At Key Stage 3, students are introduced, not only to many new concepts but also have to learn new skills. Whilst we cannot conduct experiments, we can certainly discuss the results of experiments, the theoretical aspects, assist with analysis, help students improve their mathematical skills and help students improve the quality and organisation of their written answers.
