1. School CO 2 Net Start of an educational project around Groningen University Harro A.J. Meijer (CIO) and Martin J. Goedhart (IDO) Goals:  Let pupils experience: CO 2 is NOT exotic, but measurable at and around school (and in the class room)  Learn about making measurements (reliability, calibration)  Learn about the carbon cycle  Learn about atmospheric processes and basic meteorology  Learn about climate issues and global change in general

2. Necessity (1): Instrumentation CO 2 analyser: needs to be - reliable - cheap - yet reasonably accurate Analyser of choice: Vaisala GMP 343 Supply secondary schools with a monitoring station consisting of : a CO 2 analyser and a basic meteorological station

3. (1) Instrumentation (cntd): For monitoring:- Wind speed and direction - Temperature, pressure and humidity Our choice: Davis Vantage Pro wireless. Extras: solar insolation, precipitation amount Select a basic meteorological station

4. Necessity (2): Data handling Database system for - Data storage and processing - Visualisation - Data exchange between schools - Availability of the CIO station Lutjewad data - General information about the project - Educational materials and links

5. Necessity (3): Educational material Use the existing network between the didactics organisation of the u. Groningen natural science faculty and secondary school teachers - Consider both the measurement results and the measurement process - Huge potential for pupil exam projects - Texts, leaflets, booklets - Excursions taking the CO 2 analyser along (class room, parking houses, pastures, crop fields, woods, greenhouses) -Visits to the participating schools by CIO scientists - Site visits by school classes or groups of pupils

6. Practicalities -Financing: First 3 schools paid by private Dutch foundation (Gratama foundation). One school in the city, one in the "suburbs", one rural. - Team of 8 interested schools is formed for educational material development, 5 of them on the waiting list for equipment Time Schedule July 2005: Gratama foundation grants application September 05:Selection and Purchase of instruments November 05:Elementary form of data base ready November 05:Start of Educational material development December 05:Installation of the devices on the roofs of the schools

7. Outlook - General enthusiasm among secondary schools - More funding needed (about 5 k€ instrumentation per school) - If project extends: personnel support will be needed beyond our CIO research group (at present only few months of student assistance included in application) Extension with the Wageningen E-mission project (Hilhorst) European dimensions??
