Recently, we were visited by seventh and eighth grade students from Libellus, a private elementary school in Bratislava, as part of their Chemistry and Biology course. An interactive workshop on how science is done was prepared for them, where they were told about the basic principles of science, about cells in the blood, neutrophils and how they create traps for bacteria. What it means to publish in a good journal and how to formulate and test hypotheses was not left out.
