去年9月开学后,曹老师带我们在操场上测量了杆的影长,探究太阳高度角和杆影长度的关系,但在短短一节课内并没有取得实际结果。曹老师建议我们在周末选择天气好的一天再测量。我出于好奇,主动向他借了测量的“宝贝”——太阳高度角测量器,并在他指导下学会了独立使用太阳高度角测量器。回到家,爸爸和妈妈鼓励我要有耐心,同时帮助我把观测地点定在家里的大阳台上。9
After starting school in September last year, Cao took us to measure the length of the pole in the playground and explored the relationship between the altitude of the sun and the length of the pole shadow. However, in a short course, no actual results were obtained. Mr. Cao suggested that we choose a good day on the weekends and then measure. Out of curiosity, I volunteered to borrow the measured “Baby” - solar elevation angle gauge and, under his direction, learned to use the solar elevation angle gauge independently. When I got home, my father and mother encouraged me to be patient, and at the same time, help me set the place for observation on the terrace at home. 9
