On Saturday, February 23, 2019, took place the eighth workshop of “Γλαfx”. The children carried the starry sky to the lab. Through S.T.E.M. activity, using Styrofoam glasses, cardboard and the Star Walk 2 application, they built a constellation projector. Having first learned about space and constellations, through the application, each child chose his favorite constellation to take it to his projector. Then in a dark room and with the help of a flashlight, they projected their constellations. In addition, each group has made a poster to showcase their work and transfer their experiences from the program to the FIRST LEGO League qualifier in Xanthi.
