Abstract: 

In a society that generates information rapidly, schools have to fulfil their programmes<br>imaginatively. Thus, extra-curricular activities may be helpful for the students to acquire wider knowledge<br>than that they may get within the classrooms. On the other hand, randomness is present in almost all everyday<br>decisions, mainly based on prior information so it is important to have at least a rough idea on how specific<br>events may affect the chances of other events. We explore both ideas here in the context of a science fair, in<br>which two high-school senior students conducted an investigation about conditional probability using a game<br>called "Shut the box". We also want to pose, as a research question, if, after their participation in the science<br>fair, these students have reached higher levels in probabilistic reasoning compared to their classmates or have<br>acquired knowledge about concepts far beyond the official curriculum.
