Level 4: Proficient Readers. Green Lantern looks at some of the great inventions that have transformed every area of life on earth. There have been many magnificent inventions through history, and JLA member Green Lantern explores some of these, whether in transport, clothing, warfare, communications or energy – from the wheel to the Internet. Along the way he introduces his colleagues from the Justice League of America. Some use technology to help them save the world, others draw on super-powers that human invention can only hope to emulate one day...
