  1. The Earth & Beyond : Our Moon These are called the phases of the Moon. SUNLIGHT N.B. This is the view from Earth

  2. The Earth & Beyond : Our Moon Crescent Moon N.B. This is the view from Earth.

  3. The Earth & Beyond : Our Moon Half Moon N.B. This is the view from Earth.

  4. The Earth & Beyond : Our Moon Gibbous Moon N.B. This is the view from Earth.

  5. The Earth & Beyond : Our Moon Full Moon N.B. This is the view from Earth.

  6. The Earth & Beyond : Our Moon Gibbous Moon N.B. This is the view from Earth.

  7. The Earth & Beyond : Our Moon Half Moon N.B. This is the view from Earth.

  8. The Earth & Beyond : Our Moon Crescent Moon N.B. This is the view from Earth.

  9. The Earth & Beyond : Our Moon New Moon N.B. This is the view from Earth.

  10. During a lunar eclipse the Moon is on the opposite side of the Earth to the Sun. During a lunar eclipse the Earth blocks the Sun’s light from reaching the Moon. Where must the Moon be for a lunar eclipse to take place?

  11. During a solar eclipse the Moon moves directly between the Sun and the Earth. During a solar eclipse the Moon blocks the Sun’s rays from reaching part of the Earth. Where must the Moon be for a solar eclipse to take place?

  12. The Earth & Beyond : Eclipses • A solar eclipse happens when the Moon comes in between the Sun and the Earth. This casts a shadow over the Earth.  The last solar eclipse over the UK was on 11th August 1999. Solar eclipses don’t occur very often.  A lunar eclipse happens when the Earth comes in between the Sun and the Moon. This casts a shadow over the Moon.  Lunar eclipses happen in most years.

  13. Draw the lunar or moon eclipse and the solar or sun eclipse H.W

  14. The Earth & Beyond : Probes & Satellites For thousands of years humans have been fascinated by the night sky and what lay beyond it.

  15. The Earth & Beyond : Probes & Satellites Science Fiction writers first suggested the idea that we could put artificial satellites into orbit around the Earth. This only became reality in 1957 when the Soviet Union placed Sputnik I and Sputnik II into orbit [Sputnik II contained a live dog!]. Today, artificial satellites are launched very frequently by space shuttles and unmanned rockets.

  16. 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.

  17. 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.

  18. The Earth & Beyond : Probes & Satellites

  19. The Earth & Beyond : Probes & Satellites Meteorites, the Solar Wind and ‘space junk’ all travel very quickly through space and can damage satellites. Astronauts need to ‘space-walk’ in order to fix them.

  20. The Earth & Beyond : Probes & Satellites It can ‘see’ much further into space and give us images of stars and galaxies many light years away, like this cartwheel galaxy. Astronomical satellites like the Hubble Space Telescope [HST] are large telescopes placed in a high orbit far from the effects of the Earth’s atmosphere.

  21. The Earth & Beyond : Probes & Satellites On July 4th 1997, NASA launched the ‘‘Pathfinder’ Discovery Mission to Mars. It cost $150 million and used the ‘Sojourner Rover’ buggy to test Mars’ atmosphere, surface and weather, amongst other things. Our search for answers and clues to the origin of the solar system and the possibility of life elsewhere led to the development of unmanned space probes. For years, science fiction has brought us stories of Martians - but could they really exist? Or have existed?

  22. The Earth & Beyond : Probes & Satellites

  23. The Earth & Beyond : Probes & Satellites The Sojourner Rover

  24. The Earth & Beyond : Probes & Satellites Was Mars like the Earth until something catastrophic happened? The tests carried out by the Rover showed that Mars is much more like the Earth than was expected.

  25. The Earth & Beyond : Probes & Satellites The tests also showed that the crust of Mars is very similar to continental crust on Earth and that volcanoes had played a part in Mars’ formation. Why did the volcanoes stop? Did the gases they gave out kill any Martian life?

  26. The Earth & Beyond : Probes & Satellites The surface of Mars has undergone intense erosion by massive floods and by strong winds. Did it rain on Mars? How much water was there on Mars? Was there life in the water?

  27. The Earth & Beyond : Probes & Satellites 1. Give 2 uses of artificial satellites. 2. What is meant by a ‘geostationary’ orbit? 3. What problems do satellites encounter in space? 4. Why do astronauts have to wear ‘space suits’ when repairing satellites? 5. Why can the Hubble Space Telescope ‘see’ much further into space and produce much clearer images than telescopes on Earth. 6. Why didn’t NASA send astronauts to Mars instead of spending millions of dollars on the ‘Pathfinder’ Discovery Mission? 7. Give 2 reasons why there is unlikely to be life on Mars?

  28. A Earth B Jupiter C Pluto D Venus 1. What is the name of this planet?

  29. A Friction B Upthrust C Gravity D Nuclear 2. What force keeps the planets in orbit around the Sun?

  30. A Comet B Planet C Asteroid D Moon 3. What object from the Solar System is shown?

  31. A 28 days B 24 hours C 365.25 days D 365 days 4. How long does it take the Earth to spin once on its axis?
