Aims:
• to promote investigation rather than lectures
• to present the research world to students
• to have student’s projects in March 2007
In these aims, we will
• propose experimental materials with many choices of protocols
• visit classrooms to▪ launch the project and raise questions
▪ present research jobs
• propose classrooms to visit our laboratory

Three subjects of thinking:
• dendrochronology,
• study of carbon sources and sinks,
• study of carbon exchanges between atmosphere and ocean.

Questions
• Can we get climate information from trees?
• Are all rings of a tree similar?
Experimentation
• How to measure rings?
• Working in groups -> measure precision and experimental error
• Edit the profile “ring width versus years”
dendrochronology
Modeling
• From experimental results and with meteorological data, construction of a model “ring width and meteorological events”
Model validation
• Profiles for past centuries (Xth or XVIIIth century) will be analyzed and compared with historical texts.

Questions
• Where does atmospheric CO2 come from?
• How is atmospheric CO2 regulated?
• Is the atmospheric CO2 concentration similar all through the day, all through the year?
Experimentation
• CO2 concentration measured in several places
• Construction of little greenhouses with CO2 sensors
Aims
• Understanding of the carbon cycle (daily and seasonal)
study of carbon sources and sinks

study of carbon exchanges between atmosphere and ocean
Questions
• Does any exchange occur between atmospheric and ocean CO2?
• Are they similar all over the Earth?
• What changes in the ocean produce atmospheric CO2 rises?
Experimentation
CO2
Sea water
clam
