Uli is visiting his grandfather and realizes that he has become forgetful. In his opinion, Grandpa definitely needs a computer to help him in such situations. To his surprise, however, his grandfather claims that he still has a small computer in the garden shed and shows him a sunflower seed. At first, Uli is very disappointed, but when Grandpa explains that this tiny seed contains all the information for a huge sunflower, he is thrilled and his interest in the processes of nature is awakened. Since many children in elementary school are already aware of the fascinating possibilities of a computer, this book offers a motivating introduction to the equally interesting seasonal processes of nature right outside their door.
