The International Space Station weighs almost 400 tonnes and covers an area as big as a football pitch. It would have been impossible to build the Space Station on Earth and then launch it into space in one go – there is no rocket big enough or powerful enough. To get round this problem the Space Station was taken into space piece-by-piece and gradually built in orbit, approximately 400 km above the Earth’s surface. We tried to figure out if the ISS would fit in our playground.  In class, we looked at plans and diagrams and worked out how each section was connected. It was lots of fun but we now realise, why it took soooo long to build!!!
