Science Arena

20190427 – STEM Games logo – Arena S – bijeli tekst(1)

In the Science Arena, students will solve project assignments in different branches of Chemistry, Biology, Biotechnology and Biophysics. The aim is to solve an exercise in the most efficient, realistic and a budget-friendly way.


Hijacking the brain

Have you ever wondered if it were possible to hijack someone’s brain? What would it take? The Science Arena will be exploring small molecules that have the power to become evil rulers of our brains. These molecules can manipulate us, take control of our lives and eventually take some of them. We will uncover their molecular pathways so that we can prevent them from hijacking more brains than they’ve hijacked already.


Project Assignment

The project assignment consists of three related stages. The competition will be organized in three days each of which represents one competition stage. Teams will be given an assignment in the morning, deal with it during the day and present their solutions to supervisors in the afternoon. Team solutions are graded and ranked each day. The best teams will qualify for and compete in the finals in the fourth day of the competition when they will present their solutions to a panel of judges who will announce the winner of the Science Arena.

Who might compete in the Arena

Full time students studying in the field of Natural Sciences and the related subfields of Chemistry, Biology, Biotechnology and Biophysics (recommended but not limited to) can compete in the Science Arena.
