SFB 754:  Climate - Biogeochemistry Interactions in the Tropical Ocean

• Subject Area: Geosciences ; Biology ; Medicine
• Term: from 2008 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 27542298

SFB 754 Outreach conducts dedicated courses on SFB 754 topics at schools, in summer schools and in special programmes for pupils and teachers. To complement these, it will create an experiments brochure with instructional videos for classroom experiments. These materials (in German and in English) will be presented to teachers in a series of training events, and they will be freely disseminated to schools via the SFB 754 Outreach website, an SFB 754 YouTube channel and through the school programmes of the SFB 754's partners.
