Our science class made a “warm map” of the street between school and the station. At three points, we placed a thermometer in the shade and waited for its reading to settle. We also used a safe surface thermometer, with our teacher, to compare sunlit pavement and a bench beneath a tree.
The pavement was warmer at that moment, but our results did not tell us the temperature of the whole town. Time, cloud cover, and the material under the sensor could all affect a reading. We marked these conditions beside our numbers.
The most useful part of the map was a route. A short walk past several trees felt easier than the direct route across an open square. We asked the student council to consider this when making a summer walking guide.
A single number did not tell the entire story. The pattern of shade, surfaces, and where people actually walked helped us turn measurements into a question about daily life.

Chinese translation
科学课上，我们给学校到车站之间的街道制作了一张‘热度地图’。在三个地点，我们把温度计放在阴凉处，等待读数稳定。我们还在老师指导下使用安全的表面温度计，比较阳光下的人行道和树荫下的长椅。
那一刻，人行道的温度更高，但这组结果不能说明整个城镇的气温。测量时间、云层多少、传感器下方的材料，都可能影响读数。我们把这些条件也标在数字旁边。
地图最有用的部分是一条路线。虽然经过几棵树的路稍绕一点，走起来却比穿过空旷广场的直路轻松。我们请学生会在制作夏季步行指南时考虑这一点。
单个数字不能讲出全部情况。树荫、路面以及人们实际走的地方所形成的规律，让我们把测量结果变成了一个有关日常生活的问题。

Background notes (Chinese)
对比路面温度时，测量条件和地点很关键。学生记录了阴影、时间等因素，也没有把三处读数当成全城气温；他们用观察结果讨论更舒适的步行路线。
