摘要《一天的气温》是人教鄂教版小学《科学》四年级下册第一单元“天气与气候”的起始课，具体学习内容是使用气温计测量气温，描述一天中气温变化的大致规律。科学实践活动“用气温计测量气温”，包括4个教学环节：认识并学习使用气温计；测量不同地点的气温，学会正确测量气温的方法；测量并记录一天中不同时间段的气温；根据连续测量的气温数据绘制折线图，借助统计图描述一天中气温的变化规律。这些环节一环扣一环，循序渐进，充分关注了环节之间的内在逻辑联系，体现了学习进阶的特点，既遵循了小学科学观测活动的一般流程，又符合学生思维发展的一般规律。

Abstract： "The temperature of a day" is the starting lesson of unit 1 "weather and climate" in the second volume of grade 4 of Science in the primary school of Hubei Education Edition of people’s education. The spe？ cific learning content is to measure the temperature with an thermometer and describe the general law of temper？ ature change in a day. The scientific practice activity "measuring temperature with thermometer" includes four teaching links： understanding and learning to use thermometer； Measure the temperature in different places and learn the correct method of measuring the temperature； Measure and record the temperature at different times of the day； Draw a broken line chart according to the continuously measured air temperature data， and describe the change law of air temperature in a day with the help of statistical chart. These links are linked step by step， paying full attention to the internal logical relationship between links， reflecting the characteristics of ad？ vanced learning. They not only follow the general process of scientific observation activities in primary schools， but also comply with the general law of students’ thinking development.

Keywords： thermometer； temperature measurement； temperature variation law
