Enhanced descriptions from Syndetics:

This fun and educational series brings a fresh new approach to the many aspects of invention. It traces the history of over 120 great inventions and inventors, from prehistoric times into the 21st century and beyond. looks at a problem in a lively cartoon story...thinks of a possible solution - maybe something a little crazy but often holding the germ of a good idea...comes up with way of solving the problem - and eureka!...sets to with ideas for a make-and-do model...and finally, tests it out. And while these ideas are building, there's all the science behind each invention to find out about too! From crossing rivers to hauling heavy loads, this title of the Crafty Inventions series poses the problems that lead to 10 of the very first inventions. Work out how the wheel transformed people's everyday lives and why the spear became a cutting-edge weapon. Then re-create a cave painting, build a hut-on-stilts and craft your own raft, bridge and water dipper.
