A Way to Enjoy Physics!

           “In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is itself often more valuable than twenty formulae extracted from our minds.”– Albert Einstein

            As what Albert Einstein had said, “A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds,” this means that the teaching of physics is clearly enhanced by the use of demonstrations. These provide an opportunity to illustrate the scientific method and teach the students to relate experimental observations to scientific theory. Experiments represent the means by which scientific knowledge has advanced so rapidly in modern times. Finally, not to be underestimated, demonstrations make the learning of physics much more enjoyable!

            Recently, the 4th year students of Minglanilla National Science High School conducted several demonstrations. Examples of these are The Burning Water, The Match Missile, Detergent Propelled Boat, The Singing Glass, Magic-Come-Back-Can, Funny Reflection and many more! All of the demonstrations have been thoroughly tested in a classroom setting. The students selected demonstrations that are so especially striking or provocative manners, as well as some of the standard demonstrations that can be presented in diverse, but unusual ways.

            In part, this reflects each feeling that is necessary to come by the attention of the students and convince them that Physics is interesting before any real learning can occur, because there seems to be a little help available for the student who wants to improve the quality of his or her presentation, the usual style of physics demos is to list the important concepts and to give a large number of demonstrations to illustrate one by one.

            The apparatus required for each demo varies considerably in complexity. Some of the demos can be done with equipment available at home or from a local hardware store. Others are best conducted from components found in a well-equipped physics laboratory or available from specialized vendors.

            Although most of the demos are completely safe, a few of them involve potential dangers, and should be carried out by someone who is knowledgeable in physics as well as in experimental technique.

            As one of the presenters, I could say that physics demos not only arouse the interest of the students but also help them in their studies; besides, demos enrich students’ knowledge regarding this subject.
