生物科学是一门实验科学。让学生在家里动手做些观察实验,也是不应忽视的一个方面。因为中学生物实验取材广,简便易做,但往往培养期长,需要连贯性的观察,这使家庭实验成为必要与可能。可以根据教学内容,有计划的给学生拟定实验的题目和方法。例如: (一)种子的萌发目的要求:证明水分、空气和适宜的温度,是种子萌发的外界条件;胚是形成幼苗的内在依据。实验材料:菜豆种子、玉米种子。 Biological science is an experimental science. Let students do some observation experiments at home, but also should not be overlooked in one aspect. Because of the wide range of biological experiments in secondary schools, easy to do, but often long training period, the need for coherent observation, which makes the family experiment necessary and possible. According to the teaching content, students can plan to experiment with the topics and methods. For example: (A) the germination of seeds Purpose requirements: to prove that water, air and the appropriate temperature is the germination of the external conditions of the seed; embryo is the basis for the formation of seedlings. Experimental materials: bean seeds, corn seeds.
