Abstract

There is a growing concern over the decrease in student interest in the sciences. The atmosphere of entry-level science courses, particularly in the quantitative sciences, has been suggested as one cause of the loss of student interest (1). Investigations have shown that giving a formal lecture to any freshman science student by no means delivers information. Moreover, adequate learning is not guaranteed when students simply sit and listen to a lecture (2–5). To capture students' attention to the subject and to make the lectures interesting, various methods are suggested in the literature (6–8). We suggest that some simple riddles can be used effectively to make students interact in class. This method requires the student to provide answers to riddles in order to develop the discussion about a given topic. The riddles asked need not involve a quantitative problem, but are simply a means for evoking the material being discussed, as opposed to presenting it as a lecture. Here we report simple riddles on elements and their compounds to provide novelty to the freshman lecture in chemistry.
