    1.3 On line Pretest for students

    - Pretest for students  (there is also in pegagogical module Pre-test (Learningapps) et PDF papier pour pretest)

    2. Measurements

    2.1   Before the measurement
    Experimental preparation of the measure (choice the gnomon, test verticality, choice of a good spot at school with min declination of the ground). 
    Be informed of the updates in the work procedure for the organization of measures over special several days (equinox or solstice Strategies)

     

    2.2 During the measurement

    • Measurements of the height of the gnomon, and the length of the shadow
    • Photography of the gnomon/shadow at solar noon and optional photographs or videos of the (team) work of the students

    2.3 After the measurement - Publish data

    • Post of the measurement to social networks (school, date, time,  gnomon, shadow, photo of the measurement)
    • Post of the measurement to twinspace project journal by admin student
      photo + data (school, date, time,  gnomon, shadow, names of the students that were responsible for the measurement)
    • Publication of the data of measurements on a shared google spreadsheet of the month (in the Google sheet, it is the one with the tab  "data" ) (This step is of great importance to be done as soon as possible as the results of the measurements are created daily by the admins)
    • Publication of the photos in your school photo gallery of the TwinSpace and optional in your school's google sub-folder in the   "School gallery 2021" shared folder.
    • Updating your school page - best practice is to use a google slide for gathering photos and data of the measurements per month

     

    3. Eratosthenes observation and method

    3.1 Present the historical experiment :Eratosthenes method

    3.2 Present how the collaboration among schools makes Eratosthenes method valid for any date: Eratosthenes collaborative measure

    Forum activity: https://twinspace.etwinning.net/220567/forum/267906/thread/3236382

     

    4. Video Conferences

    Videoconferences among all partner classes are scheduled for:

    • March/September equinox, 
    • December solstice,
    • and special events.

    It is also a recommendation to the partners to schedule video conferences bilaterally any time available for their classes

     

    4.1 Before the Video conference
    Admins: Create online event in twinspace (Twinspace > online meetings > name of event). Call for the participation of the partners.
    Partners are requested to sign up to the event.

     

    4.2 During the Video conference
    Partners visit  Twinspace > online meetings > name of event.
    Partners need to download adobe connect and enter the meeting room.
     

    Short video https://www.youtube.com/watch?v=3o5MD8urHdI (from 1’- 2.27’) with instructions.

     

    4.3 After the video conference
    Admins: Publication of the video conferencing

     

    Organise the content of videoconferences

    Verification of results, estimation of measurement quality from the 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.
    Preparation of the videoconference with the slides (country-city-school-student-made)/ slide shared to the partners to prepare their students. Extra presentations/games/online joined activities are implemented with the ideas that partners share in a “vc preparation google slide”
     

    5. Experimental activities &  transdisciplinar activities 

    The basic experimental activities are presented in the page: https://twinspace.etwinning.net/220567/pages/page/2120605

     

    Ideas for other experimental and transdisciplinar activities

    -Media Literacy: A debate with “valid sources”: Flat earth?

    -Alternative models of the earth, why not possible, "what if ..." case

    -Following the traces of human knowledge about the earth and its movements

    -Satellites

    -Solar system (planets' movements around the Sun in comparison to Earth)

    -When Eratosthenes met Euclides, or Thales, a celebration of Thales Day

    -Time from prehistory to nowadays: when do we start to talk about times, meanings of times, measurement of time

    -paired schools to create a quiz for the other country using the photos and the facts that their mate has posted so far. A collective quiz after for all the partners

    -Culture exchange activities among partner countries
