Non renewable - fossil fuels (coal, oil and gas) and nuclear fission. Renewable – solar, wind, wave, biomass, geothermal, tidal, hydroelectric, nuclear fusion. be able to describe advantages and disadvantages of each energy resource know that many energy resources e.g. wind, fossil fuels, are ultimately dependent on the sun’s energy Space You should: be able to state the planets that make up our solar system in order from the Sun know that the solar system is part of the Milky Way galaxy which is part of a much larger universe. be able to describe why we have day and night know that a year is the length of time it takes a planet to orbit the sun Magnetism and Electromagnetism You should: know that only certain metals are magnetic be able state that like magnetic poles repel and unlike poles attract be able to describe how a compass works be able to draw the shape and label the direction of the magnetic field of a bar magnet be able to state that the magnetic field is strongest at the poles be able to describe how to construct an electromagnet be able to describe how to increase the strength of an electromagnet Waves You should: understand that all waves transfer energy from one point to another know that in TRANSVERSE waves the particles vibrate at RIGHT ANGLES to the direction of motion of the wave know that in LONGITUDINAL waves the particles vibrate PARALLEL to the direction of motion of the wave know that SOUND waves are LONGITUDINAL know that WATER waves and ELECTROMAGNETIC waves e.g. LIGHT , INFRARED, RADIO etc, are TRANSVERSE know the meaning of AMPLITUDE and WAVELENGTH know that the units of AMPLITUDE and WAVELENGTH are in metres or cm or mm know how to label AMPLITUDE and WAVELENGTH on a wave diagram Electromagnetic Waves You should: know the names of the different waves which form the electromagnetic spectrum be able to arrange the different parts of the electromagnetic spectrum in order of increasing or decreasing wavelength know that electromagnetic waves do not need a medium to travel through know that all electromagnetic waves travel at the speed of light in air or vacuum know that all electromagnetic waves are transverse waves know that all electromagnetic waves carry energy or transfer energy be able to recall some uses and dangers of electromagnetic waves. The Atom You should know that: everything is made of atoms atoms are extremely small atoms are made up of a nucleus and shells the nucleus contains protons and neutrons electrons orbit the nucleus in shells protons are positive; electrons are negative; neutrons are neutral protons and neutron have the same mass, electrons are 2000 times lighter atoms are neutral (number of protons equals number of electrons) Electrostatics You should: know that plastic materials can be charged by friction know that positively charged objects have a deficiency of electrons and negatively charged objects have a surplus of electrons know that like charges repel and unlike charges attract be able to describe two uses of electrostatics – dust removal and spray painting be able to describe how sparks can be dangerous – lightning and tankers Electricity You should: know the circuit symbols for a battery, bulb, switch, ammeter, resistor, variable resistor be able to use the circuit symbols to draw simple circuits and be able to describe how they work know that a complete circuit is needed for a bulb to light know that conductors allow electricity to flow through them and insulators do not know that conductors have free electrons and insulators do not have free electrons understand that current is a flow of charge carried by free electrons know that conventional current flows from the positive of the battery to the negative of the battery and electrons flow from the negative of the battery to the positive of the battery know that current is measured in amps using an ammeter recall that the current is the same everywhere in a series circuit know that resistance is measured in ohms and is the opposition to the flow of the current describe how a variable resistor can be used to vary the current in a circuit and make a dimmer switch know that when current flows in a wire the wire heats up – explain why the wire heats up and give some examples of how this heating effect is used at home, e.g. toasters know what a parallel circuit is and be able to describe how the current splits up along the parallel branches be able to explain what is meant by a “short circuit” be able to describe some of the dangers associated with electricity Speed You should be able to: calculate average speed from measurements of distance and time using the equation: Average speed = total distance / total time re-arrange the average speed equation: distance = average speed x time time = distance / average speed Forces You should: know what forces can do know that there are two types of force, and give examples of each be able to state the definition of centre of gravity know when an object will topple over and when it will remain stable know that FORCE is measured in newtons know that MASS is measured in KILOGRAMMES know the difference between MASS and WEIGHT Know and use the equations: • weight (N) = mass (kg) X 10 • weight (N) = mg know that a force can cause an object to turn know that the turning effect depends on the size of the force and where it is applied know the equation: moment = force x distance know that a moment can be measured in Ncm or Nm know the principle of moments and be able to apply it to unfamiliar situations be able to explain when a lever is a force multiplier be able to explain when a lever is a distance multiplier Kinetic Theory: You should be able to: plot a scatter graph and draw a line of best fit comment on the reliability of results displayed on a graph identify mathematical relationships from graphs state the differences between solids, liquids and gases describe the changes of state that occur between solids, liquids and gases Heat Transfer You should: be aware of the difference between temperature and heat know that there are 3 methods by which heat energy is transferred be able to describe an experiment which shows that different materials conduct at different rates be able to identify which materials are good conductors and good insulators and state some uses know that convection occurs in fluids (liquids and gases) know how convection arises be able to describe experiments which show convection taking place in water and air know that a medium is needed for heat transfer by conduction and convection know that radiation is heat transfer by infra red (heat) rays know that radiation can travel through a vacuum know and be able to demonstrate that dull black surfaces , when hot, are the best emitters of radiation know and be able to demonstrate that dull black surfaces are the best absorbers of radiation know that shiny surfaces are the best reflectors of radiation
