On December 21, 2020, Aycan TETİK ALGÜL's Team from 14 EYLÜL SECONDARY SCHOOL and Şehit Abdulkadir Yıldırım Secondary School Ümran ACAR team met online with zoom. First we introduced ourselves. Then we started using our web 2.0 tools. They watched the informative video about MARS, our FIRST web 2.0 tool prepared by NASA. Then, we held a quiz contest via https://www.educaplay.com/learning-resources/7986505-m_ars.html. After the quiz, the students played the fun game about MARS at https://kahoot.it/. After the games were over, we met in the chat room of the Twinspace page and evaluated the activity we had realized. My students met with Ümran ACAR's team in the forum room. They evaluated our effectiveness The activity our Ümran ACAR teacher applied to our students in the meeting.
