Starting the project: Schools and students presentations
Presentations and exchanges between pupils,
Communication of the geographic coordinates of the school
Localization on a Google map
With more than 3000 photos of measures, we prefer to store them in the folders of a Google drive, to not slow down the display of the page materials/images. The page materials/images is reserved for school photos, Geogebra figures (about 500) and screenshots of tables of measures (about 500) are also published in materials/images
(you must be member of the Eratos Google group to edit some of the Google documents)

Depending on specific conditions (curriculum, level of students, etc.), schools adapt their annual progress. A progression in 5 sequences is proposed in the Pedagogical module.
Fixed dates such as the solstices (June and December) and equinoxes (March and September), as well as the World space week (October 4-10) are rendez-vous for which participation is strong. European schools are also mobilizing to coordinate measures for "no noon shadow days" which concern schools in the intertropical zone.
Coordination of the measures
Teachers are in constant contact to coordinate action at other events (India International Science Festival, Encuentro de Astronomía de Colombia) It is rare for a measure posted in real time on social networks to remain orphaned. Teachers are mobilized to ensure another measure and allow a collaborative calculation.
Before any measure
Experimental preparation of the measure
Organization of measures over several days (equinox or solstice Strategies)
Students are organized in international teams: Task forces
During the measurement
Determination of the solar noon
Measures of the height of the gnomon, and the length of the shadow,
Photographies and videos
After the measurement
Instant communication through social networks
Pooling of internet documents :
Publication of the results of measurements on a shared google spreadsheet of the month in "School data" .
Publication of the photos in your school photo gallery of the TwinSpace and in your google "School gallery"
Verification of results, estimation of measurement quality from ephemeris
Looking for the best partnership in a shared spreadsheet in Google drive
Choice of the partner school which will lead to the nearest calculation 40000km.
Drawing the geometrical figure of the measurement, followed by calculation of the circumference of the Earth using a Geogebra model.
Publication of the results in the day page
Publication of the month newsletter
