On the following sites you will find lots of information about the InfoSphere – Student Laboratory for Computer Science at the RWTH Aachen.
The InfoSphere offers different approaches to various facets and applications of computer science for children and teens covering all school grades. There are half-day and full-day modules as well as modules that stretch over several days. Modules contain research- and 'Puzzle'-projects and, above all, a hands-on experience. Many of the modules were designed for middle schoolers, so that no prior knowledge is required, and can be booked for every grade. Some of the modules can be easily integrated into high school computer science classes, to broaden the knowledge on covered topics with a field-trip or as an alternative to in-class teaching.
