This paper summarizes a brief history on the two after-school activities, ProjectBSD and NELab. Both activities shares the same aim: to find students who have an intention to be great but do not know how to do it, to get them together, to organize them into one group, and to wait for a chemical reaction between them to cause. What the author prepares is just a room and computers. It is the practice of active learning. Since our activities spanned rather long period of time, fifteen years, only this paper cannot describes the details, and the author just chronically introduces the two activities, and specific analyses of them form the point of view of learning sciences will be dealt on another paper.

Methyl Orange (MO), one of the water-soluble azo dyes, is well-known as pH indicator extensively used in secondary schools and post-secondary education institutions of chemistry. Besides, azo compounds are applied widely in imaging industries including the textile, paper, printing, and food industries. In the present study, researches on the chemical structures of MO, the positions H+ attaches in MO appear to be unclear, are described historically, dealt with acid-base reaction, ammonium-azonium tautomerism in acidic aqueous solutions by means of UV-Vis spectroscopy. Furthermore, problems in the textbooks of analytical chemistry due to misunderstanding the difference between resonance theory and tautomerism are pointed out for precise learning the structures of MO and its protonated species in an aqueous solution. X-ray crystal structures of MO are shown to support teaching students of chemistry too.
