Cell Biology -
This topic extends the work done in Year 7 and 8 and students learn about the structure and nature of cells and how they develop. This topic also covers the two ways in which cells divide in the human body and transport in cells including diffusion, osmosis and active transport.
Energy -
This unit explores how different energy transfers take place and how electricity is made using the National Grid. It will also involve a high demand in the use of numeracy where students will need to be able to analyse data and use equations.
Cell Biology - 30 Mark end of unit assessment covering: Cell structure, cell division, transport in cells.

Atomic structure & the periodic table -
Students will learn how the periodic table provides chemists with a structured organisation of the known chemical elements from which they can make sense of their physical and chemical properties. The historical development of the periodic table and models of atomic structure provide good examples of how scientific ideas and explanations develop over time as new evidence emerges. The arrangement of elements in the modern periodic table can be explained in terms of atomic structure which provides evidence for the model of a nuclear atom with electrons in energy levels.
Revision & Required practical activities - This time will be used to revise topics to date and consolidate prior knowledge. Students will also undertake the Required practical activities for these topics.
Atomic Structure and the Periodic Table - 30 minute end of unit assessment covering: Models of the atom, symbols, relative atomic mass, electronic charge & isotopes, periodic table.
Organisation -
In this topic students explore how cells work together and focuses, in particular on how the digestive, circulatory and respiratory systems function. In each case they provide dissolved materials that need to be moved quickly around the body in the blood. Students learn how the plant transport system is dependent on environmental conditions to ensure that leaf cells are provided with the water and carbon dioxide that they need for photosynthesis.
Bonding, structure and properties of matter -
Chemists use theories of structure and bonding to explain the physical and chemical properties of materials. Analysis of structures shows that atoms can be arranged in a variety of ways, some of which are molecular while others are giant structures. Theories of bonding explain how atoms are held together and scientists use this knowledge to engineer new materials.
Organisation - 30 minute assessment covering: Principles of organisation, animal Tissue, organs & organ systems, plant systems.
Bonding, structure and properties of matter - 30 Mark end of unit assessment covering: Chemical bonding, How bonding and structure are related to the properties of substances, structure and bonding of carbon.

Particle Model of Matter & Atomic Structure -
In this topic students revisit work from Year 7 on changes of state but this is done at a molecular level. They also consider the behaviour and energy changes of particles when substances change from one state to another. In addition, students explore the different types of radiation from atoms. They look at the effects, uses and the hazards that of each type of nuclear radiation. Students will use mathematical skills to determine the half-life of different types of radiation and furthermore, determine how old a substance may be based on the radiation it emits.
