    • Life in the Universe Is there any body out there?
    • Is this man right?
    • Communication on planet Earth Boys vs girls Make a time line of when these methods of communication were first used 250 000 years ago modern humans evolve Today Stagger the events correctly on the time line Which ones are long distance – which ones can be used to communicate with aliens
    • It only took Four Billion years for life on Earth to look for Extra Terrestrials
    • SETI The SEARCH for EXTRA Terrestrial Life
    • Where should we point our radar dish? The sky is a big place so where do we want to look first? Well, we know of one planet that has lots of life
    • Thinking of Earth as a planet orbiting a star deep in space what are the conditions that allow it to support life? For any thing to be alive they must be able to A planet with life on it is likely to have ..... Write in your books this sentence and complete With as many ideas as you can
    • The Drake equation
      • The Drake equation states that:
      • where:
        • N  is the number of  civilizations  in our galaxy with which communication might be possible;
        • R *  is the average rate of  star  formation per year in  our galaxy
      Write a list of things that would need to happen for us to contact intelligent life?
    • The Drake equation
      • where:
        • N  is the number of  civilizations  in our galaxy with which communication might be possible;
        • R *  is the average rate of  star  formation per year in  our galaxy
        • f p  is the fraction of those stars that have  planets
        • n e  is the average number of planets that can potentially support  life  per star that has planets
        • f ℓ  is the fraction of the above that actually go on to develop life at some point
        •   is the fraction of the above that actually go on to develop  intelligent  life
        • f c  is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
        • L  is the length of time such civilizations release detectable signals into space .
    • Where do I live? Design an Alien to live on a certain planet Create your planet first then an Alien which will evolve to fit the environment
