摘要
利用手机热成像技术拍摄“浓硫酸加入水中”和“水加入浓硫酸中”这2个不同操作呈现的温度变化,将看不见的能量变化转化成可视化的颜色变化,加深对浓硫酸稀释规范操作的理解,发展学生的证据推理意识。
This paper introduces the use of mobile phone thermal imaging technology to capture the temperature changes in two different experimental processes of“adding concentrated sulfuric acid to water”and“adding water to concentrated sulfuric acid”.The invisible energy changes are transformed into visual color changes,deepening the understanding of the standardized dilution operation of concentrated sulfuric acid,developing students’awareness of evidence reasoning.
