ODTÜ’de Bilim Eğlencelidir / Science is fun at METU
A competition was organized as a part of “Science is fun at METU” science-fair organized by Middle East Technical University in order to attract and engage high-school students in scientific activities. Science-fair took place at METU Campus on November 14th, 2014 as a full-day event.
About 100 traffic cones were arranged in a parking lot similar to the basal plane of a hexagonal crystal. Therefore, each traffic cone represented an atom. Students used a 2D coordinate system similar to the crystallographic directions. Coordinate system and crystallographic directions and arrangements were introduced to the students at the beginning of the competition.Then, 10 artifacts (clues) were randomly placed under the cones. These artifacts are related to some basic materials science knowledge. After providing the correct answer, students were directed to the second artifact.
Questions and directions got harder and complicated after each clue. Overall, 70 students participated in the competition individually or in groups. Only 1 group of students answered all 10 clues correctly and they are awarded by an Apple Ipad Air. They decided to receive a gift card equal to the price of Ipad and shared the gift card equally. All of the students, however, successfully found their way in the crystal without making any mistakes. At the end of the day, they all knew why atoms in solids arrange themselves in a crystallographic manner, the purpose of the crystal and crystallographic directions and common materials science knowledge.
