Science

Objectives:

Biology

- Describe the structure and function of the digestive system. Identify the components of healthy diets and describe what these components are used for. Explain where the different components are digested using knowledge of enzymes.
- Identify the steps involved in plant reproduction, including pollination, fertilisation, seed dispersal, germination and growth.
- Identify the parts of the respiratory system in human and to describe the difference between aerobic and anaerobic respiration.
- Identify the main groups of unicellular organisms. Compare prokaryotic and eukaryotic organisms.
- Describe the causes of variation with species and explain how this variation is linked to the evolution and extinction of species.
- Describe the adaptation of plants and explain how these adaptations impact on the growing of crops.

Chemistry

- Describe how fuels are burned, what the products of burning coal are and how they affect the environment.
- Describe the structure of an atom, properties of elements and how they are arranged in the periodic table.
- Describe the properties of metals and how they react with water and acids. Describe how properties of metals change when they are mixed with other elements.
- Describe how rocks are formed, describe their properties and explain how they are broken down and transported.
- Describe and explain the properties and use of different materials, for example, polymers and ceramics.
- Identify the reactivity of different elements and use this to predict chemical reactions.

Physics

- Describe and explain how forces and particles affect the observed behaviour of fluids.
- Describe how light can be refracted and explain how this can be used to produce pictures from cameras
- Describe and explain energy transfers and evaluate the cost efficiency of different appliances
- Describe how the movements of the Earth within space cause changes to the seasons, the impact of the Earth’s magnetic field and calculate the weight of objects.
- Use mathematical equations to calculate speed and work done and explain the effect of turning forces
- Describe changes to current and voltage in series and parallel circuits and explain how electromagnets work.
