This explains day and year length, seasons and the visibility of objects from Earth.-1651046355A100A1Describe the appearance of planets or moons from diagrams showing their position in relation to the Earth and Sun.-1651074930A200A2Explain why places on the Earth experience different daylight hours and amounts of sunlight during the year.-1460548895K200K2Our solar system is a tiny part of a galaxy, one of many billions in the Universe. Light takes minutes to reach Earth from the Sun, four years from our nearest star and billions of years from other galaxies.-1651062230A300A3Describe how space exploration and observations of stars are affected by the scale of the universe.-1651057785A400A4Explain the choice of particular units for measuring distance.-1651010604500Key words-1460555245K300K3Galaxy: Collection of stars held together by gravity. Our galaxy is called the Milky Way.-1460532385K400K4Light year: Distance light travels in a year (over 9 million, million kilometres).-1460555245K500K5Stars: Bodies which give out light, and which may have a solar system of planets.-165108382000-1460546990K600K6Orbit: Path taken by a satellite, planet or star moving around a larger body. Earth completes one orbit of the Sun every year.-1460544450K700K7Exoplanet: Planet that orbits a star outside our solar system.53975876303003Extend-1460559055E100E1Predict patterns in day length, the Sun's intensity or an object's shadow at different latitudes. -1460549530E200E2Make deductions from observation data of planets, stars and galaxies.-1460564770E300E3Compare explanations from different periods in history about the motion of objects and structure of the Universe.-1355452157E400E4-1206561595E500E5 ................
