In this unit pupils learn that micro-organisms share the characteristics of other living things, find out about growing micro-organisms to make products, and about the role of micro-organisms in infectious diseases. They learn about the body's defence systems and how immunisation can protect against microbial infections. - Top |

In this unit pupils learn that characteristics are inherited and how this is used in selective breeding, why selective breeding is important and about variations arising from environmental differences. - Top |
||
 |
||
| In this unit pupils learn how the human respiratory, digestive and circulatory systems interact to maintain activity, about the functions of the skeleton and about ways in which diet, exercise, smoking and drugs affect health. - Top | ||
 |
||
| In this unit pupils explore the properties of metals and non-metals, learn that different acids react in similar ways with metals, with metal carbonates and with metal oxides. They represent elements by symbols and compounds by formulae and use word and symbol equations to describe these reactions. - Top | ||
 |
||
| In this unit pupils learn that although metals react in a similar way with oxygen, water and acids, some react more readily than others. They establish and use a reactivity series for metals and represent chemical reactions by word and/or symbol equations. - Top | ||

||
| In this unit pupils explore a range of useful energy transfers and transformations and discuss the use of electricity as a convenient way to transfer energy to do useful things. They associate the concept of voltage with the transfer of energy in a circuit and investigate the voltage of cells. They also study how electricity is generated, with reference to environmental impacts and use the principle of conservation of energy to identify ways in which energy is dissipated during transfers. - Top | ||

||
| In this unit pupils learn about the gravitational pull between bodies; how it depends on the masses of bodies and the distance between them. They relate the movement of planets around the Sun, and that of satellites around the Earth, to gravitation and study how artificial satellites are used to observe the Earth and provide information about the solar system and the universe. They also find out about space exploration. - Top | ||
 |
||
| In this unit pupils use the concept of speed, consider the relationship between forces (including balanced forces) on an object, and its movement. They study the effects of water and air resistance on speed, and how streamlining reduces these effects and use ideas of balanced and unbalanced forces to explain the movement of falling objects. - Top | ||
 |
||
| In this unit pupils study pressure on solids and describe applications of this in everyday appliances and study hydrostatic pressure in fluids and describe an application, eg hydraulic jack . They describe the operation of levers, including examples from the human body, which depend on the turning effect of a force and learn about the principle of moments. - Top | ||
