作为一项为期三年的纵向研究，探讨了儿童（11岁至14岁）的物质概念的发展，本文报告的结果与儿童的理解沸水和颗粒的想法。证据表明，对于大多数的学生，粒子的想法提供了手段，让他们开始接受的泡沫在沸水中的水变成了气体状态。这一点的重要性，在儿童的理解的气体样品作为一个样本的物质，进行了讨论。有人认为，沸水必须被视为具有课程意义，远远超出了它与一个定义的温度。
As part of a three-year longitudinal study which explored the development of children's concept of a substance (ages 11 to 14), this paper reports the findings in relation to children's understanding of boiling water and particle ideas. Evidence is presented which suggests that, for most of the pupils, particle ideas provided the means for them to begin to accept that the bubbles in boiling water were the water changed to the gas state. The importance of this, in terms of children's understanding of a sample of gas as a sample of a subtance, is discussed. It is argued that boiling water must be seen to have a curriculum significance which goes far beyond its association with a defined temperature.
