Teaching material lists of wind, water, etc to do work, in order to make students to moving objects have energy to form more clear of the specific impression, as well as using the stage of hydropower and wind power. Raises the concept of kinetic energy, by experiment shows that the size of the kinetic energy relationship with speed, quality, to develop the students ability of observation analysis, potential energy is first introduced from the Angle of the work of teaching concept of potential energy, again by experiment or observation study of the determinants of the size of the potential energy of life phenomenon.
(2) learning the analysis of emotions
