    This is a science problem so keep religion and politics out of this.
    You can post your replies in any language you are comfortable with.

    Here's the problem :
    Can you come up with practical method to explain how sunrise and sunset happens to someone who has no knowledge about the Earth's rotation on its axis or Earth's orbiting of the sun ?
    Imagine you are explaining this to a child.

    take two balls, define one as sun and other as earth.
    Let child observe when one ball goes around the other.
    put a needle or a mark on the earth ball, define it as man.
    let child observe sun relative to man's position :D

    good but not good enough. Relativity is not something a child knows yet..

    that needs relativity to understand tho its how you perceive, the child thinks what he/she perceives is true. I think you should pass this question if asked, until the child knows that everything is not in the way that it seems to be lol

    I'm not looking for a way out here. Just thinking how something like this can be explained to someone who doesnt know anything about it or related to it.

    Ask your student to stand still looking forward. Then you walk around him. At a point he will start to see you from the corner of his eye. That is sun rise. And after sometime he will lose the site of you. That is sun set. In between is day. Is this OK...

    that is more practical with a child but it does have one problem.
    That way the child will thing the sun is going around the Earth.
    But I like your way of thought. :yes:

    yea I have an idea; but it'll need some extra stuff.
    * a camera(a web cam is ok)
    * 2 balls

    define, camera as eyes of man.
    define, balls as sun and earth.
    get earth going round and round around sun and rotate it along its axis too
    turn on the camera get live feed, and show child what 'man' observes
    thus what the child observes :D

    So this needs a webcam. A wireless one ?
    Also where to place the camera ?

    Oh yes that problem is there...

    then lets do it other way around. This time you stay still and ask your child to spin. His sight will be like this _ you _ you. (day night day night). I think this will do the job...

    yeah a wireless one is better, put it on a rather large foot ball get a bigger ball and if you can stuck up a light in it lol that's all just take the earth ball around the sun ball with the correct rotation, child will understand it :P child will understand relativity too :lol:
