    Date Gnomon(cm) Shadow(cm) Angle(°) Declination Solar noon
    01 March 30.4 -cloudy!!!-  :( -7.54 12:37

    Too pity as today theoretical angle was around 45

    (45.6)*** and we discussed the ways we could use this and the way Thales has used this to measure pyramids' height in Egypt. Finally, creation on school's google drive of a slide for March equinox

    *** for every 100cm of measured shadow the gnomon would be 100+2.1 cm

    C4 class working on google drive -presentations


    From May's activities: Working on shared google sheet

    From 26 April's activities: Eratosthenes and Van Gogh

    Δείτε το βίντεο για τον Van Gogh  και το βίντεο για τη μέτρηση της Περιφέρειας της Γης από τον Ερατοσθένη που δημιούργησαν οι μαθητές της Πετρούπολης και συζητείστε τα συμπεράσματά σας από τα δύο παραπάνω βίντεο στο mentimeter(slide2) που ακολουθεί (Watch the 2 videos that follow below ; one is about Eratostjenes method created by Petroupoli's stydents and the 2nd video is about Van Gogh. Then try to answer the questions of Mentimeter). Group discussion in class will follow.)

    Hint: Try to spot these words on the video and maybe you could use them on mentimeter

    mind -  eyes -  recognise patterns and descride them - hardest concepts in nature - art/geometry to depict the way it looks - movement - fluid  -  light - age of suffering

    Video A (created by Petroupoli's students):

    Video B about Van Gogh:

    Results in Mentimeter

    Students evaluation of the project: "A word that comes to your mind connecting to this project"




    Last year in Eratosthenes 2017 (in December 2017) Bill had created a project in scratch calculating the Distanceampng two places when their latitudes were given (we had the pleasure that project to have been remixed by our partners in Colombia and translated in Spanish)

    This year in April, a project was created in scratch by Aggelos (11th Junior High School of Ilion) which calculates the Circumference of the earth as a result of the data provided of the measurements of two partners. Aggelos team had worked the part that the two partners schools are on the same hemisphere; in checking the other cases he had help from the teacher.
