Are you looking for something to extend those students who are your Science boffins? For the last 8 years I have been involved in organizing the German BrainBee that has now expanded into a non-profit called DNO (Deutsche Neurowissenschaften-Olympiad). Originally the German BrainBee was to select the German champion for the International BrainBee, but DNO has a mission to get more neuroscience into schools so that students and teachers can learn more about the brain, nervous system and behaviour.
The competition is free to enter and all materials are in English. The students receive access to a unique study guide that has been created by a team of researchers who they will meet when they take part in the competition (21st March, in Bonn, Berlin, Frankfurt or Heidelberg*). Winners of these competitions get selected for the National Competition (April/May) and the overall winner represents Germany at the International BrainBee in Washington D.C. (August).
Outcomes: All of the information and resources necessary for their students to enter a regional neuroscience competition (DNO) in either Berlin, Bonn, Frankfurt or Heidelberg* and full support from the DNO team.
