7L Background information7La – Observing the sky/A place near the SunThe Earth spins in an anticlockwise direction (as seen from above the North Pole), making the Sun appear to rise in the east and set in the west.

There are various definitions of a lunar month. The Pupil’s Bookgives 29.5 days, which is the length of time from one new moon to the next (technically known as a synodic month).

Leap years occur every four years, except that the century years arenot leap years unless they are divisible by 400; so 1900 was not a leap year, but 2000 was. 7Lb – Moonshine

The formal names for the different phases of the Moon are, in order: new moon, waxing crescent, first quarter, waxing gibbous, full, waning gibbous, last quarter, waning crescent, and then new moon again.The same face of the Moon is always towards the Earth. No onesaw the ‘back’ of the Moon until a Russian spacecraft called Lunik 3 sent back pictures in October 1959. The first samples of Moon rock were brought to Earth by the Apollo

Latitude and longitudeThe Earth is divided up by a series of grid lines that allow locations to be identified by a set of coordinates. Lines of latitude runaround the Earth, parallel to the Equator. Lines of longitude run from the North Pole to the South Pole.longitude

EclipsesA solar eclipse occurs when the Moon comes between the Earth and the Sun, and the eclipse is only visible from small areas ofthe Earth. There is a total eclipse (where the Sun is completely obscured) somewhere in the world every two or three years. Partial eclipses occur when the Moon does not completely cover the Sun.At present, the relative sizes and distances of the Moon and Sun are such that the Moon’s disc is almost exactly the same apparent sizeas that of the Sun. This has not always been the case – in the past the Moon was much closer to the Earth, and total eclipses would then have been visible over a wider area. The Moon is gradually moving away from the Earth, so eventually there will be no total eclipses at all because the

Equator

Before the advent of electronic navigation aids, a ship’s positionat sea had to be determined by reference to the stars, and by using a very accurate clock (called a chronometer). Latitude was determined by using a sextant to measure the angle above the horizon of a known star – calculations and reference to datatables could convert this measurement to a latitude. To determine longitude, a navigator would note the time of local noon (i.e. when the Sun was at its highest point) using a clock set to Greenwichtime – hence the need for an accurate clock. For every hour’s difference, the ship was 15º east or west of Greenwich. The first chronometers accurate enough to be used for this purpose were built by John Harrison in the second half of the 18th century – a story told in Dava

A lunar eclipse (when the Moon moves into the shadow of theEarth) occurs at full moon. The Moon is usually still visible during a lunar eclipse, although as a dark disc (often with a red colour). Thisis because the long wavelength red light is refracted by the Earth’s atmosphere, and some of this reaches the Moon Eclipses do not happen every month because the plane of theMoon’s orbit around the Earth is tilted slightly compared with the plane of the Earth’s orbit around the Sun.Time zones

Local time depends on longitude. All time zones are referenced to the Greenwich Meridian – hence Greenwich Mean Time, or GMT. GMT has now been superseded by Coordinated Universal Time (UTC), which is still referenced to the Greenwich Meridian and is based on time from atomic clocks rather than being directly related to the Earth’s rotation. The abbreviation came about becauseEnglish-speaking countries wanted the abbreviation CUT, but the French phrase for Coordinated Universal Time is

TidesThe gravitational pull of the Moon causes tides (Worksheet 7Lb/5), but the difference between high and low tide varies through the month. When the Sun, Moon and Earth are in line (at new moon and full moon) the effect of the Sun’s gravity is added to that ofthe Moon, and the tidal range (difference in height between high and low tide) is high; these tides are called spring tides and there are two each month. When the Earth, Sun and Moon are in an L- shape (at first quarter and last quarter) the Sun’s gravity partially counteracts the effects of the

Each time zone is approximately 15º wide. A place 30º east ofGreenwich would, in theory, be 2 hours ahead of UTC. However this simple geographic rule is complicated by international agreementson common time. For instance, Spain, parts of which are west of the UK, is one hour ahead because it sticks to central Europeantime. Nepal is 5 hours and 45 minutes ahead of UTC, just to make their time different to Indian time which is 5 hours and 30 minutes ahead of UTC. In some places the lines defining the time zones bend around islands or follow national boundaries, to keep all of a country inside one time zone. At a longitude of 180º is the international date line – again this line bends to keep all of a country on the

The surface of the MoonThe dark areas visible on the Moon were once thought to be seas, hence the name ‘mare’ (pronounced mar-ay), from the Latin forsea (plural ‘maria’ (mar-ee)). After further investigation, including the return of rock samples by the Apollo missions, these areasare now known to be lava flows. Similarly, at one time the craters on the Moon were thought to be volcanic in origin, but it is now known that they are impact craters caused

The relative ages of different parts of the Moon’s surface canbe worked out from the principle of superposition – if featureA appears to be on top of feature B, feature A must have been formed after feature B. In the case of the Moon, any crater whose ejecta spread across surrounding features must have formedafter those surrounding features. Any lava flow that appears to fill

Pluto is not always further from the Sun than Neptune. Pluto’sorbit crosses that of Neptune, and from 1979 until 1999 Pluto was actually closer to the Sun than Neptune – this will not happenComets are large balls of (mainly) ice in highly elliptical orbitsaround the Sun. As comets approach the Sun, a stream of gas and dust particles formed by evaporation streams out forming the ‘tail’.A collision with a comet (or part of a comet) is thought to have caused a violent explosion at Tunguska in Siberia in 1908, when more than a million square kilometres of forest were flattened.There is often some confusion about the terms meteor andmeteorite. A meteor is the trail of light seen as small dust-likegrains burn up in the Earth’s atmosphere. Meteorites are fragments of solid material that reach the Earth’s surface –

A more quantitative estimate of the age of the lunar surface canbe made by counting the number of craters. The older the surface, the more impact craters you would expect to see. However it is not quite as simple as this! The early Solar System was full of lumps of rock that could cause impacts. As time progressed, and many of these rocks had actually hit planets or moons, the rate of impacts slowed. Estimates of the changing rates can be made by studyingthe surfaces of various bodies in the Solar System, which can help in estimating the ages of surfaces.You would expect that the Earth would have been subjected to a similar number of impacts as the Moon, as it is in roughly the same place in the Solar System. The reasons why there are so few craters apparent on the surface of the Earth include:

Our Sun is an average sized star. It only appears bright because weare so close to it. If we could move to Pluto, the Sun would appear almost as distant as any other star in the night sky. The biggest starsIt is a common misconception that there is no gravity in space,fostered by pictures of astronauts floating around their spacecraft. This is obviously untrue since it is the Earth’s gravity that keeps the Moon orbiting the Earth. There is a point between the Earth and Moon (closer to the Moon than the Earth) where the gravitational fields cancel each other out, but even this point is still subject tothe gravitational field from the Sun and, to a far lesser extent, other bodies in the Solar System.Satellites remain in orbit because the combination of their speed and the gravitational attraction of the Earth gives them a curvedpath that ‘falls’ around the planet. Most GCSE physics texts

• the Earth’s atmosphere destroys many smaller bodies through

heating• a body falling in the ocean is not likely to leave a crater• weathering of the Earth’s surface removes signs of smaller craters• plate tectonics changes the surface of the Earth, and so

7Lc – A plan for all seasonsIt is a common misconception that summers are hotter because the Earth is closer to the Sun in the summer. The Earth is in fact slightly further away from the Sun in the northern hemisphere summer– which is why a northern hemisphere summer would be slightly cooler than summer at the equivalent latitude in the southern hemisphere.

Our normal sensation of weight is due to the fact that the groundor floor is stopping us falling down towards the centre of the Earth. In orbit, the astronauts inside a spacecraft are attracted towardsthe Earth with exactly the same force as the spacecraft itself, and so feel no sensation of weight. This state is often referred to as‘weightlessness’, although this is not meant to imply that

The tilt of the Earth’s axis is approximately 23.4° at present – thisangle varies between about 21.8° and 24.4° over a 40 000 The Arctic Circle is an imaginary line around the Earth 23.4° fromthe North Pole (measured from the centre of the Earth) – the significance of this is that for anywhere north of the Arctic Circle there is at least one day in each year when the Sun does not riseabove the horizon, and at least one day when the Sun does not set. The Tropic of Cancer is 23.4° north of the Equator, and this is the furthest north that the Sun is directly overhead on at least one day each year. The Antarctic

All four of the ‘gas giant’ planets (Jupiter, Saturn, Uranus andNeptune) have rings, although Saturn’s rings are by far the most spectacular. The rings consist of millions of small particles of ice (‘dirty snowballs’) orbiting in one plane.An account of the discoveries of Uranus, Neptune and Pluto is given in Tom Standage’s The Neptune File.In 2006 Pluto was ‘demoted’ from a planet to ‘dwarf planet’ by the International Astronomical Union. Two other objects were also designated as dwarf planets, and more may be added to this category as further observations are made of the outer Solar System. Theother two dwarf planets (at the time of writing) are Eris, which

ObjectivesAll pupils must:

(1) recall that we live on a planet called Earth which gets heat and light from the Sun

(2) describe some of the evidence for the Earth being spherical(3) explain that a day is the time taken for the Earth to

spin once on its axis(4) explain that a year is the time needed for the Earth

to orbit the Sun once, and why we have leap years(5) recall that the Moon orbits the Earth once every 29.5 days.

Correctly use the words astronomer, axis, day, Earth, leap year, lunar month, Moon, orbit, satellite, sphere, Sun, year.

Most pupils should:(6) recall that the Sun rises in the east and sets in the west(7) appreciate why some people are fascinated by astronomy(8) explain why the time is different in different parts

of the world(9) describe, in simple terms, how the circumference of

the Earth can be measured using shadows.Correctly use the word ellipse.

Question 2 is designed to help pupils to recall some of what they learnt in KS2. As the theme of the first few topics of this unit is using a model (i.e. our current model of theSolar System) to explain observations, it is worth making sure that pupils understand the difference between an observation and the explanation for it.• Must: the AT document link on page 163 opens Observations – a document with more detailed questions about the movements of the Sun and Moon, which can be used in place of question 2

I – how would this affect the weather?)• PMI: the Earth should have more than one moon.

(Possible answers: P – it would not get as dark at night, because there would be two moons to provide light; M – if it were brighter at night we would not be able to see as many stars; I – do other planets have more than one moon?)

• PMI: the Earth should spin faster on its axis. (Possible answers:

P – days would be shorter, so we would not have to go to school for as long each day; M – there would be more days in a month/ year, so we would have to go to school more often; I – would we be able to go to sleep at the right times?)OOO: Sun, Earth, Moon.

Encourage them to draw the different shapes that the Moon canappear to be, and to put their drawings in order. Ask for ideas about why the Moon appears to be different shapes.

Explaining tasks

1: Practical: Phases of the MoonDemonstrate the phases of the Moon using a torch or other light source to illuminate a sphere (a blown-up balloon will do). Theroom will need to be darkened. Group the pupils together, with the light source at one side of the room, and walk around them withthe sphere, showing that the part of the Moon they can see is not always fully illuminated. Higher-attaining pupils can then be asked to draw the shapes they see when the ‘Moon’ is illuminated from different angles – many pupils find this difficult, particularly if the room cannot be made dark enough.

Exploring tasks

1: Phases of the MoonAsk pupils to record the shape of the Moon over a period of time. Exercise care when giving explanations and instructions to children about how to accomplish these observations. Pupils should betold not to go outside at night without the permission of a parent/responsible adult; possibly even accompanied by the adult. Most,if not all, of these obserations can be accomplished by looking through the windows from inside the house/flat. It Resources

happen everymonth – this is because the plane of the Moon’s orbit is at a slight angle to the plane of the Earth’s orbit around the Sun. The diagramat the top of page 167 may help to explain this. The Moon is not often in a direct line between the Earth and the Sun at the correct point in its orbit. Even when it is, the shadow the Moon casts onthe Earth is small compared to the size of the Earth, and so total eclipses are only seen from small areas of the Earth.

1: Pupil’s Book pages 168–169 (AT)This explains the reasons for seasonal changes. Worksheet 7Lc(1) is the Access Sheet for this topic.

1: What if? questionsAsk pupils to suggest what would be

different if:Afl

• the Earth was further away from the Sun (year length longer,

weather cooler)• the Earth spins at a different rate (shorter days if it spins faster)• the Earth’s tilt was less (less difference between

The AT animation link on page 169 opens Explaining day lengths– this explains why the length of a day varies with the seasons, and also varies with the distance north or south of 2: Practical: Seasons demonstration 1Use a globe to demonstrate the seasons. A purpose-made globeis best as such globes are usually mounted at the correct angle to demonstrate the tilt of the Earth’s axis. A strong light source suchas a slide projector or overhead projector works best, in a darkened room. A blob of Plasticine® or similar stuck on top of the UK may help pupils remember which part of the globe they live on. Remember to spin the Earth in an anticlockwise direction so that the Sun appears to be rising in the east, and to maintain the tilt of the ‘Earth’ as you move it around its ‘orbit’ so that it is always

Answers to these questions will allow you to judge how well pupilshave understood the explanation of the seasons. Pupils can be asked to describe these differences in writing.2: Quick CheckA

flThe Quick Check sheet provides a set of statements to

be usedas a ‘connectives’ exercise. The statements cover the content of thisand previous topics. Connectives are a set of sentences for pupils to complete in their own words, including one of the followingconnecting words: and, because, but, however, such as, therefore, which, to. The worksheet can be handed out to pupils, or it can be copied onto an OHP slide or the list can be written on the board. Pupils can be given 5 or 10 minutes to complete their sentences, and then they can share their ideas with the class. The obviousanswers to most questions involve using ‘because’ as a connective, but higher-attaining pupils should be encouraged to use the other connectives if they can, and to

ResourcesGlobe; slide projector or overhead projector; Plasticine®.

3: Practical: Seasons demonstration 2As a follow up to Explaining 2 (demonstrating the seasons using a globe and strong light source), use a light sensor and datalogging equipment to record the length of the ‘day’ as you slowly turn the globe. Move the globe so its axis is tilted in a different direction relative to the light source, and repeat the measurement. Help pupils to relate the orientation of the axis to the ‘Sun’ with the lengths of the days measured. It is important to keep the speedof rotation of the globe the same for all measurements if a fair comparison is to be made. It may be worth discussing this aspect of the demonstration with pupils. Alternatively, if two light sensors are available, it should be possible to record data for (say) the UK and southern Australia at the same time, thus avoiding this difficulty.• Could: ask pupils to predict the variation in day

length in equatorial regions, and then test their

ObjectivesAll pupils must:

(1) recall that the other planets are spheres orbiting the Sun(2) recall that the Sun is a star and it is enormous

compared to the planets(3) explain that we see the other planets because they

reflect light from the Sun.Correctly use the words planet, Solar System.

Most pupils should:(4) obtain and recall information about the planets in the Solar

System, plus asteroids and comets(5) explain that the temperature of a planet and

length of its year depend on its distance from the Sun

(6) describe some ways in which ideas about the Solar System have changed over time

(7) describe some of the conditions on other planets or moons, and how this information has been found.Correctly use the words asteroid, comet, inner planet,outer planet.

• The first AT video link on page 174 opens Observing the stars

– this shows Owen talking about the stars and other objects that can be observed with telescopes.

• The second AT video link on page 174 opens Constellations – which explains what constellations are and how different cultures have seen different patterns in the sky.

5: Quick Quiz revisitedA

fl Revisit the 7L Quick Quiz to test pupils’ knowledge of thecontent of this unit. If you have the ASP on CD-ROM use Quick Quiz2 which provides the same activity but with the answers arrangedin a different order. Pupils could fill in their answers on the 7L Quick

3: International astronomyWorksheet 7Le(3) looks at how astronomers collaborate in terms of using observatories on opposite sides of the world, contributing both funding and expertise to international projects, and also at theprocess of peer review.

6: Astronomy club displayA

flAsk pupils to compile a display to introduce

newcomers tothe local astronomy club. The display will use photos and diagramsfrom the Pupil’s Book (see suggested list below), and pupils need to write captions to explain what the pictures show. The selection of photos and their captions should explain what we know aboutthe Earth and its seasons, the Moon and the planets, and stars. This activity can be done as an assessed task. A sheet of level descriptions is provided on page 310 of the ASP. If used for this purpose, you may wish to ask pupils to expand verbally on anycaptions that are short on detail. If time permits, pupils could also choose photos from the internet and compile a

1: Quick CheckA

fl The Quick Check sheet provides a set of questions andanswers that can be cut out and made into cards. These cards can• give pupils just the shaded question cards and ask them to write

down the answers• use the cards as a question loop activity (in this case

each card should contain a question and the answer printed next to it)

• use the cards to play dominoes (again, each card should consist of a question and an answer)

• use the cards to play snap, where a ‘matching pair’ is a question and its correct answer (each card should be just one question or one answer)

• give pupils or groups of pupils the cards and ask them to match the questions and the answers, or have a competition to see which group can match all the cards in the shortest time (each card should be just one question or one answer)

• play a card matching game (pairs or pelmanism) where all the cards are laid out face down, and pupils take turns to turn over two cards. If the two cards are a matching question and answer,the pupil keeps the cards. If they are not, the cards are turned face down again and the next pupil takes their

Use the 7L End of Unit Test. A mark scheme is given in the ASP. Encourage pupils to identify areas that are still weak and toformulate plans to strengthen those areas.

The second AT presentation link on page 174 opens Ideasabout the stars – this shows children giving various ideas about thestars. If this was used at the beginning of the topic (Starter 1), ask pupils to look at the comments they noted down and to make any necessary amendments. Pupils can then

9: Level ladderA

fl Pupils should tick the boxes on the Level Ladder to recordthose statements that they feel they know. Alternatively they canuse a traffic light system or the CRI index (see Introduction, page17) to record degrees of certainty. Ideally pupils should be certain of all statements at a level to be sure they are

If it has not been used already, show each statement in turn andask pupils to comment on it. If they disagree with the statement ask them to explain why.3: Test questions and mark schemeA

flAsk pupils to make up a set of test questions on the

contentof this topic or the content of the unit as a whole. Each group couldwrite a question worth 4 marks, and also write a mark scheme for it. The questions could be given to other groups and thenthe answers compared with the mark schemes as part of
