Tweet

I'm entering this space challenge which is set up by my science department. The prize is a trip to kennedy space centre and yes if i win, i'll be going to america and hallelujah, i will be able to meet the astronauts and visit the admin area and watch rockets launch. it will be a brilliant oppurtunity for me which i can't miss. Rolling Eyes Very Happy ok here's my challenge: - design an ecosphere to allow human life on another planet in the solar system. You cannot choose earth. - your entry should demonstrate internet based research and should be firmly based in ICT. - you need to consider the requirement for life and how you should use science to support human needs. ok as a starter, i have no idea what ecosphere is and it's kinda confusing to me. im thinking of doing a powerpoint presentation for this research but CAN SOMEBODY PLEASE HELP ME WITH THIS CHALLENGE? can somebody explain to me about ecosphere? because i'm pretty confused here
