Summary:This study aims to make 4th grade students understand why thermal convection occurs. For this purpose, it is necessary to promote the relationship between the 4th grade units “How things warm up” and “Temperature and volume of things.” We verified the effectiveness of demonstration experiments with water balloons and water cooling, and the introduction of watching videos of solar balloons. Few of the children who received regular classes (control group) answered that water and air became lighter and increase in volume when heated together. On the other hand, many (experimental group) who participated in demonstration experiments with water balloons and water cooling and watched videos of solar balloons responded in such a way. A significant difference was confirmed between the control and experimental groups. The results suggest that it is effective to introduce demonstration experiments of water balloons and water cooling and watching videos of solar balloons to make 4th grade children understand why thermal convection occurs.
