任教小学科学已经有两年了,深感遇到的实验不少,可真正让学生做的不多。就要上《通电线圈》了,我决定让学生们自己也做一回探索者。于是我准备好实验材料:导线、铁钉、磁铁,电池由学生自备。让学生来制作电磁铁并判断一下磁极。到教室一说,学生也欢天喜地热情高涨,于是师生意气风发进入实验室。

Teaching primary school science has been two years, a lot of deep experience experiments that can really allow students to do much. It’s up to the “power-on coil,” and I decided to have the students themselves do the explorer again. So I prepared the experimental materials: wire, nails, magnets, batteries prepared by the students. Have students make electromagnets and judge the poles. To the classroom said that students are also joyful enthusiasm, so high-spirited teachers and students into the laboratory.
