利用威尼尔传感器探究水蒸气的温室效应*

利用威尼尔(Vernier)传感器进行实验探究,通过对比分析、证据推理可以验证除二氧化碳外水蒸气也是一种温室气体。通过威尼尔传感器实时采集不同气体样品在太阳灯模拟日光照射下的升温数据,让数据变化趋势清晰直观地呈现在眼前,使学生直观感受到平时无法可视化的温室效应现象。本实验是对中学教材温室效应有关内容的很好补充,既贴近生活与自然,又利于激发学生对化学的兴趣。

Inquiry on Greenhouse Effect Caused by Vapour with Vernier Sensors

It can be proved, through comparative analysis and evidence reasoning from the inquiry experiments with Vernier sensors, that vapour is also a kind of greenhouse gas, only less well-known than carbon dioxide to most people. Collecting data of how the temperature of different kinds of gases rise when exposing to the light of sunlamp with Vernier sensors can present a clear and evident trend of changes, helping students to have a visual perception of the normally invisible phenomenon of greenhouse effect. This experiment was relevant to daily life and the great nature, which would be a perfect supplement to the content of textbook and would contribute to an improvement in students’ interest in learning chemistry.
