Scientists are to carry out the first detailed survey of the Great Wall of China to establish just how long the ancient barricade is. The wall, the world's largest man-made structure, is estimated at over 5,000 kilometres long. Along with checking its dimensions the four-year study, which started in May 2007, will map the wall's exact route. Children will use their findings to make a slideshow advising the scientists on the best method.
- that the Earth, Sun and Moon are spheres
Children will learn:
- a method to measure a curved line
- to make a trundle wheel to measure non-linear distances
These resources were initially developed in partnership with the Centre for Science Education, Sheffield Hallam University.
