Abstract: A series of simple experiments is described, for presentation in the secondary school classroom aiming at the development of understanding Chemistry by the students rather than provoking “love” for the topic. The experiments present modifications of known procedures adaptable to practically any point of secondary education and to any level of sophistication provided by the school facilities. The simplicity, clarity of the procedures and security of the students are the factors considered as central relative to thrilling which has been a distractor in many related projects. Emphasis is placed on solutions, and especially the description of their concentration and the understanding of the meaning of the various forms this description may possess. The experiments are also related to discussions and queries which are designed to promote active thinking and develop both practical and mental skills among the students.
