explain day, month and year in terms of the relative motion of the Sun, the Earth and the Moon |
record the changes in shape of the Moon over a calendar month and use models to illustrate and explain the phases use video or computer programmes to establish the difference between the 24-hour rotation and 365-day (approximate), orbit of the Earth use a datalogger to collect data about temperature and light using a tilted globe relate these measurements to seasonal changes |
This is a challenging topic for pupils and teacher alike. The Moon orbits the spinning Earth that is itself in orbit round the Sun. Good evidence of these relationships comes from a solar eclipse, when Earth, Moon and Sun are aligned, with the Moon preventing sunlight from reaching us. For able pupils it is worth introducing the subject of gravitational effects on our oceans, so that when Sun and Moon pull from the same direction we get our largest tides. Similarly, the inclination of the Earth's axis can be introduced to explain seasons. There should be an appropriate emphasis on scale and pupils should be introduced to the use of light years to measure vast distances [the distance that light, travelling at 300,000 km per second (186,000 miles per second), covers in one year]. Light from the Sun takes only 8.3 minutes to reach |

During research, other familiar terms will be encountered - planets, moons, comets, asteroids, meteorites. This might help establish scale of the much larger stars and galaxies. For black holes the emphasis is on the dead star becoming smaller and smaller yet having a constant mass. Near the surface of the star there is a corresponding increase in gravitational pull, which eventually becomes so strong that |

describe the particulate nature of solids, liquids and gases and use this to explain their known properties |
observe and offer explanations of a variety of experiments: (comparing masses of identically sized blocks of different materials, putting a small coloured crystal into cold water and into hot water, trying to fit a metal bar into a gauge before and after heating, opening a perfume bottle at a distance, heating a metal rod that has paperclips attached by petroleum jelly, trying to depress syringes filled with solid, liquid and gas) observe what happens when measured volumes of dried peas and sand are mixed and use this to explain the reduction in volume occurring when alcohol and water are mixed investigate diffusion in air, in liquid and in gel predict the effect of gas pressure (collapsing can experiment), using the particulate theory |
The series of experiments should be carried out quickly. The purpose is to encourage observations and explanations. Most pupils will have incorrect ideas at this stage. They can be revisited once the particulate nature is established. The terms 'atom' and 'molecule' should be introduced with care. Particle motion is faster in a gas than in a liquid, and faster in a liquid than in a solid. Pupils find it difficult to accept that the spaces contain nothing - believing that they are occupied by air. Take particular care in explaining the pea/sand model. This subject allows for the idea that theories must be tested and that they can be used to explain the results of experiments. Models are very important in helping us to understand how nature works. |

Much of the bread is lost during the burning but a black solid is left - carbon. This is an example of a simple chemical called an element. It consists of atoms of only one type. When examining the range of materials it will be helpful to include some gases, e.g. chlorine. Prepare samples of hydrogen and oxygen to further illustrate the existence of elements. It may be helpful to point out that many elements are metals. |

group research task to search for data on five elements (symbol, state at 20 °C, metal or non-metal, magnetic or not, appearance, etc.) examine a range of metals to establish their common properties demonstrate malleability compare metals with non-metals look up melting points of common metals and non-metals. |
There are 84 metals and 21 non-metals. Metals are usually strong, malleable, ductile, sonorous. They shine when polished, are good conductors of heat and electricity and (except mercury) are solid at room temperatures.
Non-metals tend to be brittle. They are not strong, generally have low boiling and melting points and are poor conductors. |

investigate conduction of heat in a variety of materials use a spiral of paper to demonstrate convection over a heat source and observe convection using a crystal of potassium permanganate |
Conduction is explained in terms of vibrating molecules. Pupils often believe that when they touch a cold object, cold flows into their fingers, but of course the sensation is due to heat flowing out from their fingers into the cold object. This is why good conductors such as metal feel cold to the touch and why insulators, such as expanded polystyrene, feel relatively warm. Convection is explained in terms of |

Establish that air is a relatively poor conductor and so is often involved in insulation - in clothing, bedding and in newer foam lagging for pipes, etc. Expanded polystyrene could be mentioned, together with the associated fire hazards. Metals are used in radiators, cooking utensils, etc., because they are good conductors. This topic links with materials and their uses. |

use a slide projector to cast a large spectrum on a wall and identify the colours and the order in which they appear explore and record the images seen in a prism challenge pupils to find out how the coloured rays produced by a prism can be re-mixed |
The rainbow colours always appear in the same order - ROYGBIV (VIBGYOR is easier to remember!). The glass (or plastic) of the prism alters the angle of the light rays passing through. This is called refraction. Each different colour of light is refracted by different amounts, so the white light is split up into its constituent colours. |

Light travels in straight lines. It is bent (refracted) as it passes into and out of glass. The investigation lends itself to measurement of angles and the collection of more quantitative data. The ideas of reflection, transmission and absorption should be explored.

Hang an electric bell inside a jar connected to a vacuum pump and listen for sound before and after evacuating the jar. This can be used to establish the need for particles to transmit vibrations. A pencil can be used to listen to the sound, e.g., of a clockwork timer. Plastic foam, egg boxes and newspapers can all be used to reduce noise.

Pupils should be familiar with the units 'amperes' and 'volts'. Voltage may be explained as an electrical force pushing electricity around a circuit. Large voltage causes a large current. To double current we double the voltage (if the resistance does not change). A thin wire has more resistance than a thick one. The electrical resistance of a wire can produce a heating effect. |

use two spring balances to pull in opposite directions use a simple model of a see-saw to investigate relationships between opposing forces weigh a series of objects suspended in air and then suspended in water discuss balanced and unbalanced forces on moving and on stationary objects to create explanatory diagrams using arrows to show the direction and scale of the forces involved |
The readings on both balances indicate that the two forces are equal - Newton's Third Law of Motion (action force and reaction force are equal and opposite). The force x distance from the pivot, when the see-saw is balanced, is equal on both sides. If there were no friction, a trolley pushed in a certain direction would speed up and would then keep going at a constant speed once it was released. Pupils could be encouraged to draw a diagram of a car with the engine thrusting it forward so that the unbalanced force in the direction of movement results in the car speeding up. A block of wood on a table is stationary, with the downward force |

create and use keys to identify living things |
use published keys to identify a wide range of organisms, both plants and animals use computer programs to identify organisms produce simple keys to identify given groups of shells from a beach, leaves from trees, birds around the school, house plants from around the school |
Keys should be of both branched and paired statement types. The decision points in the keys should not be made too difficult and should be made on the basis of readily observable external features. The keys should also be selected to avoid unnecessarily technical language. The value of diagrams in keys this stage cannot be overemphasised. Pupils use both types of keys with ease but branching keys are easier to create than paired statement keys and should be attempted first. Many pupils will need practice in the intermediate step of converting a branched key into a paired statement key before attempting a paired-statement key |

give examples of inherited and environmental causes of variation |
group work to make collections of pictures of particular types of familiar organisms, e.g. people, cats, dogs, roses, cabbages discussion or investigation of ways in which individuals in each group are similar or different to others count and record the number of seeds in the fruit of flowering plants, e.g. peas in a pod, pips in apples or oranges, or 'petals' on lawn daisies measure and record variable features that occur in the group of pupils and discuss which are the result of inherited characteristics and which are due to environmental factors, e.g. tongue-rolling ability, ear lobes attached or unattached, left- or right-handedness and height, hand span, foot length add to or create a database to store information about features carry out an investigation into the variation in growth of seedlings such as cress, peas or beans. |
Discontinuous variation arises from inherited characteristics. An organism either shows a characteristic or it does not. In humans examples include tongue rolling, left-handedness, blood grouping, and ear lobes. Eye colour is generally included in this group but can be confusing since a range of colours exists. The presentation of the findings will be a bar graph as the horizontal axis label will be descriptive and not numerical.
Continuous variation arises from the action of environmental factors and gives a smooth grading between two extremes with the majority of individuals being somewhere towards the centre (height, leaf length, etc.). Observations should be systematic and involve measurement; the graphical presentation will be in the form of a histogram. Sensitivity to issues relating to parenthood is needed when talking about inheritance. Teachers may prefer to use fictional characters for this work. It is important to establish that some variation, e.g. height, may be a result of both inherited and environmental factors. |

In every ecosystem there is a continual struggle for survival between organisms of the same species and between different species. Competition for space, light and food might have short-term effects on survival. Successful breeding ensures species survival. Competition in plants is usually for light and moisture. Seed dispersal reduces intraspecific competition and leads to colonisation of new areas.
