Lessons were conducted for the 4th gradestudents at an elementary school concerning therelationship between temperature and the volumeof air. Teaching was based on printed materialswhich contained observation tasks with explanationsfor their results. Each of the tasks wasgiven in which the students were asked to predictits results by answering some multiple-choicequestions on it.The textbook used at the school has instructionsfor students to do an experiment early inthe introductory part in which a cork plug madeof polyethylene form is made to jump out of aflask by warming (the air in) the flask, but inour study the experiment was conducted later in the consolidating stage. In addition, our teachingincluded another observation which the studentsdid as to how the air expands and contracts insidethe flask which was held upside down on thesurface of water.Judging from the students' active involvementin the activity, their answers to the taskquestions, and their written comments after theclasses, it is considered that our teaching waseffective in awakening their interest and mhelping them understand the contents.
