1. 1. The Solar System and Beyond Year 8 Physics
2. 2. Lesson 1 Starter Write down 4 things you already know about The Solar System and Beyond
3. 3. 7L1 Lesson 1 Objectives • to know the difference in size between the sun and the Earth • to explain phenomena such as day and night, and the apparent movement of the Sun • to use a model to show that the axis of spin of the Earth is at an angle to its orbit round the Sun
4. 4. The Earth is divided up into the northern hemisphere and the southern hemisphere: Northernhemisphere Southernhemisphere Equator
5. 5. The Earth is tilted on an axisNorth poleSouth pole
6. 6. While the Earth is spinning the side that faces the sun is in ________ Sunrise
7. 7. The Earth Copy the diagram below and label it using these words: North pole South pole EquatorNorthern hemisphere Southern hemisphere North pole Northern hemisphere Equator South pole Southern hemisphere
8. 8. Day and NightOn the diagram below:a) Shade the side of the Earth which is night-time.b) Label the side of the Earth which is day-time. day- time
9. 9. The Earth spins on its axis every ___ (__ hours)
10. 10. A Moving Sun?The apparent movement of the Sun across the sky is caused by the Earth spinning on its axis
11. 11. Length of DayThe Sun is at a higher angle in the sky in summer than in winter. This means the Sun is ABOVE THE HORIZON longer in summer than in winter. So, insummer, the days are longer and the nights are shorter, compared to winter.
12. 12. The Earth orbits the sun every… …year (365 1/4 days)
13. 13. This orbit is actually a “slightly squashed” circle (ellipse)
14. 14. The Earth is kept in orbit by the force of… Gravity …and by the fact that is is moving at a high velocity
15. 15. Gravity also keeps the moon in orbit around the Earth. The moon orbits the Earth every… …month (28 days)
16. 16. strongerGravity is ________ if the planet has more mass: Earth Jupiter
17. 17. The Earth & Beyond : Day & Night  How long is one day?  24 hours  How long is one year?  365¼ days  Planet Earth spins on its tilted axis and orbits the Sun.  This causes days & nights and the seasons.
18. 18. Answers to questions in the pupils’ text: 7L1 a West h 24 hours i anti-clockwise, b South viewed from above N pole c can cause permanent damage j 1 year (365 days) to your eyes k 365 (or 365, leading to a d shorter discussion of leap years; e lower February 29th; for century-years f we would die; all life would only if not divisible by 400) end l force of gravity g Australia, China, Japan; if morning in UK then America, West Indies; if afternoon in the UK then Pakistan, Bangladesh, India (use a globe to show this)
19. 19. 7L1 Lesson 1 Review of objectives • to know the difference in size between the sun and the Earth • to explain phenomena such as day and night, and the apparent movement of the Sun • to use a model to show that the axis of spin of the Earth is at an angle to its orbit round the Sun
20. 20. • Lesson 2 Starter The Seasons In your groups discuss: Why December is hot in Australia but cold in Britain
21. 21. 7L1 Lesson 2 Objectives • to describe the differences between the 4 seasons • to explain variations in day length and climate in different seasons
22. 22. The tilt of the Earth on its axis is also responsible for the seasons:When the northern hemisphere is tilted towards the Sun, it isnorthern summer and winter in the southern hemisphere.When the southern hemisphere is tilted towards the Sun, it issouthern summer and winter in the northern hemisphere.
23. 23. Two things happenbecause of this tilt:1) The days are longer during the summer2) The weather is warmer during the summer (due to the hemisphere being closer to the Sun)
24. 24. Summer and WinterWhen is the Sun highest in the sky? Summer or winter? Sun in SUMMER at noon. Sun in WINTER at noon.
25. 25. Why?Why is it northern summer when the northern hemisphereis tilted towards the Sun?When the northern hemisphere istilted towards the Sun, the Sun isat a higher angle in the sky andthe Sun’s rays are less spreadout. Therefore, they have agreater heating effect. In northernwinter the Sun is at a lower anglein the sky because the northernhemisphere is tilted away from theSun. Consequently, the Sun’srays are more spread out andhave a lower heating effect thanin summer.
26. 26. East and WestHow does the Sun move across the sky during the day?Because the NOON is when theEarth SPINS, Sun is HIGHEST inthe Sun moves the sky.across the sky. The Sun RISES The Sun SETS in the EAST. in the WEST.
27. 27. The 4 SeasonsYour teacher will give you a slip to stick into your book like the picture below. On the diagram, shade the parts of the Earth where it is night-time and fill in the gaps. Northern Southern
28. 28. Look at the the diagram of the earth below. Notewhere the light is shining. Then drag the seasonto match the correct hemisphere in the table.

37. 37. • Lesson 3 Starter Link the Key words to their meanings Year The time taken for the Earth to spin once on its axis. Day A large object, like the Earth, that orbits a sun. The time taken for the Earth to orbit the Sun Night once. When our side of the Earth is turned away Sun from the Sun. The star at the centre of our Solar System Planet which provides almost all our energy.
38. 38. 7L2 Lesson 3 Objectives • to know that there are luminous and non luminous objects • to know that the Sun is a light source, but the Moon and Earth are seen by reflected light • to explain how the view from the Earth of the Moon causes the phases in a regular sequence
39. 39. SatellitesSATELLITES are objects that ORBIT other BODIES.Satellites are held in orbit by the FORCE OF GRAVITY ofthe body they are ORBITTING.Gravity is the FORCE OF ATTRACTION between all MASSES.The LARGER THE MASS, the greater the attraction. TheCLOSER two masses are together, the greater the attraction.ARTIFICIAL SATELLITES are satellites that are made byhumans. They have many uses:ASTRONOMY GEOLOGY COMMUNICATIONS STUDYING CLIMATE CHANGE MONITORING THE WEATHER
40. 40. The Earth & Beyond : Probes & Satellites POLAR ORBIT SATELLITES :  Low orbit around the Earth passing over North and South poles.  Earth rotates underneath them as they orbit.  Used for large-scale mapping and global weather monitoring.
41. 41. The Earth & Beyond : Probes & Satellites GEOSTATIONARY SATELLITES :  Stay above the same place on Earth.  Speed of orbit matches the Earth’s rotation.  Used for communications, satellite TV, weather forecasting, intelligence, GPS.
42. 42. The MoonThe MOON is the Earth’snearest neighbour.The Moon has NOATMOSPHERE orliquid surface water.Its surface is coveredin CRATERS madeby impactingasteroids.Several manned missions have been to the surface of the Moonand it is the only other surface that humans have walked on.The Moon is seen by REFLECTED LIGHT and it takes 28DAYS to ORBIT the Earth.
