  • Observing space

    1. 1. Observing space Telescopes LO: Be able to state why we would want to observe objects in space. Be able to describe how we observe objects in space using the Hubble telescope. Be able to explain how the Hubble telescope works & be able to provide examples of objects that it has found. TASK: Why would we want to see objects in space? Write down your thoughts on a mini-whiteboard!
    2. 2. So what did you think? • How about this for a reason why we should observe space? • http://www.youtube.com/watch?v=VNtsVP 42bOE • Other ideas?

    12. 12. Where is the best place for a large telescope on earth? • Paired activity – using the fact file below, choose the best site to place a large optical telescope. Place Latitude Population density Altitude Mauna Kea, Hawaii, USA 19 degrees N 1650 per sq m 4205 m Oruro, Bolivia 17 degrees S 150 per sq m 3710m Greenwich, London, UK 52 degrees N 3750 per sq m 28 m Kharga, Egypt 25 degree N 6 per sq m 59 m
    13. 13. Where should the telescope be placed? In my opinion, the best site for the telescope is............. This site is better than the others because ......................... ....so how can we overcome and also ....................................................... these problems? Where should .............................................. It is not perfect through, aswe put the telescope? Is there Another really good site is ........................................ somewhere else? because ........................................................... The worst site would be .............................. because ...................................................................
