I currently teach biology and geology at International School in Valbonne Sophia Antipolis, on the French Riviera near Nice.
In the past, I also worked in a few french schools in Canada, Germany and Portugal before coming back to France.
When not in the classroom, I'm a coordinator for an educational seismological network in France called ‘sismometers at school’.
Indead, working on seismometers in schools gives students (12-17 years old) more motivation and a better opportunity to focus on natural hazards knowledge as well as the use of real time databases.
I am member of the Committee of Education of EGU. I am also involved in the International Earth Science Olympiads in my country and I supervise, in my regional area, the teachers’ training program in geosciences.
It is the reason why I am working with scientists from Geoazur (CNRS) located in Sophia Antipolis in South of France.
I try to make my students or my colleagues realize how important more investigation, more field tools, more data use in science teaching are.
I involve my students in field schoolwork and in network databases. I am really looking forward to bringing more authentic science to my students.

Basalt is a volcanic rock (microlitic structure).
From a primary magma from partial melting of the mantle peridotites.
The rocks are classified as basic as base-rich (MgO, FeO) and low alkali (K2O, Na2O).
They are dark because of Fe2O3.
After the structure, density, porosity, magnetism, mineralogy of rocks, geochemists up!
The weekly question focused on the difference between the black smokers and white smokers.
All these hydrothermal fields are encountered during oceanographic explorations.
1. Black smokers: they are in the form of chimneys. Emission of sulphurous water at temperatures above 300 º C.
High levels of transition metals. Sulphide deposits in chimneys.
The answer was found by some of our frequent readers. Thank you for following us and explore with us in a fun way, all aspects of geology.
Once the candle lit, the small ring of nickel previously attracted by the magnet will stop being attracted to it and will hang in the vertical piece of wood.
When cores arrive in the lab from the drill floor, scientists and technicians study physical properties of the rocks (magnetism susceptibility for example).
Magmatic rocks contain ferromagnesian minerals (see previous enigma). During the cooling of magma, the rocks, with such minerals can 'fossilized' the magnetic field. Some rocks from the oceanic crust are very amazing.
The magma produced in the oceanic ridge, while cooling slowly, crystallizes in magmatic rocks.
The challenge for the petrologists on board the JR consists to discover the history of the oceanic crust genesis by the study of minerals in the magmatic rocks.
To resolve the enigma, it is necessary to recall the stages of the minerals crystallization.
When the magma becomes rock !
Since one month, the scientists aboard the JR have examined with the rocks coming up to the seafloor.
Once their physical properties recorded (see previous enigma), these rocks are described.
Several teams of researchers and technicians are in charge of this work.
Seven rocks cores from the ocean floor…
among them a sediment core less dense than the others hard rocks cores …
How to find it using the balance only two times ?
A enigma that can be solved as follows (see attached) :
Core on deck, core on deck
