Earth in Space

relate the movement of planets around the Sun to gravitational forces

use the library to find out about 'weightlessness' experienced by astronauts in space

discuss which objects in the Solar System will have the greatest gravitational pull

make an annotated diagram to explain the effect of the Sun on the movement of the planets

find out how we determined that the Earth moves around the Sun.

Gravity is simply a pull that is exerted by any object. Note that larger objects are not always heavier. When astronauts go into space, they experience 'weightlessness' and float about. The spacecraft and astronauts are, in fact, in 'free-fall'. That is, they are 'falling' towards the Earth but never reach it because of the speed of the spacecraft in orbit and the curvature of the Earth. What this means is that the astronauts are apparently weightless because they are 'falling' at the same speed as the spacecraft.

Over the great distances in the Solar System, it is the Sun that exerts the greatest effect on the planets. Every planet would move through space in a straight line without the Sun's gravitational pull, which causes the planets to swing round in orbit. The results of careful observations of the apparent movement of stars could be explained by Earth orbiting the Sun. We now have visual confirmation of Earth's Click here to go to the start of this Strandmovement, seen from space.

use secondary sources to find out how evidence of our Solar System has been collected

find out how we determined that the Earth moves around the Sun

make a chart outlining the history of space exploration and flight

identify some other ways in which we find out about space, using library and websites.

Sputnik was launched in 1957. Apollo 11 landed men on the Moon in 1969 using a three-stage rocket. Shuttles, which are re-usable, have been used since 1981 for putting astronauts into orbit around the Earth. Pupils should be reminded of the very limited nature of this exploration - our planet and its moon - a far cry from the 'Star Wars' fantasies. Telescopes have been used to view the heavens since the early seventeenth century. Huge and sophisticated light telescopes are used now and one of these is at the Royal Observatory in Edinburgh. Other forms of energy can now be detected, having been emitted long, long ago from distant stars. Some instruments detect part of the spectrum that is not visible, such as infrared light, whilst others detect x-rays. The quality of light reaching us tells us much about the source of the light. Spectroscopes are used to study this. Radio telescopes are used to detect radio Click here to go to the start of this Strandwaves from space.

Pupils should be encouraged to look at the particles in the rock as well as colour. Help pupils to understand that the same material can be 'pebbles', 'stone' and 'rock'. To investigate wearing away, two rocks can be rubbed together. Take care that rocks are rubbed gently and that particles do not get into pupils' eyes. Permeability can be tested by dropping small quantities of water on to the rock.Click here to go to the start of this Strand

Nitrogen (78%), oxygen (21%) are the major constituents of the atmosphere. Argon, little known, is the third major at 1%, whilst carbon dioxide makes up a surprisingly small 0.03%. Uses for gases include nitrogen for freezing food, oxygen which we need for breathing and which can be used to make hot flames for welding, argon for filling light bulbs (it does not burn) and carbon dioxide for fizzy drinks and fire extinguishers. Nitrogen gas can also be changed by combining it with other substances to make plant fertilisers that are very important in Click here to go to the start of this Strandfood production.

describe what happens when materials are burned

investigate burning, with close teacher supervision, of a range of materials and select appropriate ways of recording findings

demonstrate the effect of putting a large glass container over a lighted candle floating in a trough of water

collect samples of fabrics and their labels that indicate fire-retardant properties and make links to safe living

make a poster illustrating some of the hazards of burning things

The source of heat should be limited to a night-light candle in a metal container and it may be necessary to carry out the investigation as a teacher demonstration. Use a spent matchstick, a strip of paper, cotton, wool and nylon threads, held over the flame using two wooden clothes pegs to grip the test material (taking care!). Avoid plastics, which are highly flammable. You are advised to try out the activity for safety before allowing pupils to become involved. The results involve the output of heat and light energy, smoke and residual black carbon. Invisible gas is also produced. These are irreversible chemical changes. The experiment with the floating candle can be used to provide a focus for discussion on what is needed for things to burn (oxygen in the air) and what is produced (water, invisible gas, new material). It may be appropriate to introduce the idea of a chemical reaction taking place.Click here to go to the start of this Strand

using a variety of clear liquids, e.g. tap water, salt water, coloured ink and distilled water, predict whether each liquid is pure or whether it has dissolved material in it and devise a test to find out

You will need to set the scene by reminding pupils about solutions and the use of soft paper (blotting paper or filter paper) to separate solids and liquids. The salty solution can then be allowed to dry, when the water evaporates, to leave pure salt. This can be tasted with care, using only a fingertip touched to the salt.Click here to go to the start of this Strand

describe the effect of burning fossil fuels use reference books to find out what fossil fuels are and what happens when they burn

debate actions that we could take to reduce carbon dioxide output from the burning of fuel and draw up a list of class proposals for action.

Coal, oil and gas are our fossil fuels, having been formed millions of years ago from dead organisms. They all yield lots of heat energy on burning so they are good fuels. They produce carbon dioxide and water too when they burn. Increasing carbon dioxide is worrying us because it acts like glass in a greenhouse - it lets heat from the Sun in but not all of it is allowed to escape, so the atmosphere is slowly warming. This is the 'greenhouse effect'. Because of this, we regard the carbon dioxide increase as pollution.

Nuclear energy, hydroelectricity, wind power, cycling, public transport, higher road-tax charges, etc., together with international agreements, provide a large canvas for exploring responsibilities, Click here to go to the start of this Strandconsequences of actions, etc.

distinguish between 'heat' and 'temperature' 

measure the temperature of warm water in a mug and at intervals as it cools, keeping clear records of findings.

give an explanation of the drop in temperature, referring to the heat energy that is being lost. monitor and record the temperature, in a range of places over 24 hours, using a temperature sensor

Avoid using hot water and mercury thermometers. Use a digital thermometer for safety. Temperature tells us how hot an object is; this is usually measured in degrees Celsius (ºC). However, this measure does not tell us how much heat energy the mug contains. A mug of water at 45ºC has a temperature of 45ºC and a certain amount of energy. If we add a second mug of water at 45ºC the temperature remains the same but we have doubled the amount of heat energy.Click here to go to the start of this Strand

Lenses that curve inward - concave lenses - produce smaller, upright images. Those that curve outwards - convex lenses - are more interesting. They magnify, and if used to focus an image on a screen, seem to turn things upside down. The idea of 'focus' can be introduced through examination of sharp and fuzzy images.

carry out an investigation to test the predictions and make an organised report, including findings.

The more bulbs in a circuit, the less bright they become. If one bulb 'blows' the circuit is broken and no other bulbs will light (this happens with some Christmas tree lights). If more batteries are added to a circuit (remember, + to -) then a bulb becomes brighter; if too much electricity flows, the bulb will 'burn out'. Bulbs are made to match a certain number of batteries. Multiple batteries are usually used in torches to give a Click here to go to the start of this Strandvery bright light.

visit a hydro-electric scheme

discuss the relative merits of conventional and hydro power generation, with respect to the environment

discuss the environmental impact of the generation of electricity and the energy wasted as a consequence of the many energy transfers

Essentially this requires an appreciation that energy in fuel is used to heat water. The resultant steam turns a turbine, which causes magnets to turn in a generator. This action converts movement into electricity (the steam is cooled to reform water in large cooling towers). Hydro electricity is significant in Scotland, where falling water drives the turbines.

Air pollution and heating effects on rivers have been associated with conventional power stations. Carbon dioxide effects may be referred to, though gases of the air and the effect of burning fossil fuels are considered under 'Earth and Space'.Click here to go to the start of this Strand

Conversion & transfer of energy

draw up a simple list of rules for safe use of electricity in our homes

Introduce the National Grid. The current from the power station is carried to our homes through thick, overhead power lines carried by pylons. The current in the power lines is very small but the voltage is very high. This makes transmission of the electrical energy more efficient. Before reaching our homes these high voltages are reduced by 'transformers', located in 'substations', from 400,000 to a nominal 230 volts. As the voltage decreases the current again increases. The current is then carried in underground cables to our homes where meters show how much electricity we use. Note that voltage is not properly introduced until Level E. Dangers to avoid include wet hands, frayed leads, overloaded sockets, changing bulbs when the lamp holder is live. Click here to go to the start of this Strand

investigate the energy resource in foods.

The term 'resource' is used in preference to source to encourage the idea that energy is not some kind of material like fuel (the energy resource). When fuels burn they release energy that make things happen. Oil, gas, wood, coal and peat are the common examples, but look out too for paraffin, candles, petrol, diesel. Food may also be named as an energy resource. Click here to go to the start of this Strand

Forces & their effects
describe the relationship between the Earth's gravity and the weight of an object find out what happens when a ping-pong ball and a golf ball are released at the same time from a height of two metres establish the link between weight and gravity by using a forcemeter to weigh everyday objects.

Gravity is the name of the force that causes all objects to attract one another and which pulls objects towards the centre of the Earth. Gravity makes all objects accelerate towards the ground at the same rate but most people find this difficult to believe and so they expect heavier objects to fall faster. (Take care, since air resistance can slow down the falling object so results may not always be convincing.)

Weight is the force of gravity on an object - it depends on both the strength of gravity and the amount of matter that makes up the object. Weight is measured as a force - newtons - but this need not be introduced until Level F. Interestingly the unit kg is used to measure 'mass'. In common usage 'mass' is often referred to as 'weight'.

Variety & characteristic features
give the main distinguishing features of the major groups of flowering and non-flowering plants

group examples of flowering plants into those with long narrow leaves with parallel veins (e.g. grasses, iris, daffodil, tulip) and those with leaves of a variety of shapes with veins forming branching patterns (e.g. sycamore, horse-chestnut, geranium)

examine and draw examples of non-flowering plants from the local environment, e.g. lichens, mosses, ferns, algae, conifers, etc.

survey a part of the local area, school building, etc., and locate and identify examples of flowering and non-flowering plants.

Flowering plants are subdivided into two large groups, technically known as monocotyledons and dicotyledons - terms that relate to the existence of one or two 'seed-leaves' inside the seeds - but the leaves of the mature plants can themselves be used as the basis for recognition. At this stage it is not necessary to use these technical terms. Interested pupils could use magnifying lenses to look at pea, bean, sunflower or maize seeds and to plant the seeds and observe their growth and leaf vein patterns. Colourful posters of non-flowering plants can be obtained and pictures can be downloaded from various websites.

Pupils should be encouraged to discuss the plants found and to discuss how they identified the plants. This will encourage their observation skills and the use of the distinguishing features.Click here to go to the start of this Strand
