我校(甘肃酒泉二中)几年来,注重利用本地条件,积极开展生物课外活动,引导学生通过各种渠道学习生物知识,取得了明显效果。其中一项主要活动是参观地区农科所。每当百花盛开的春夏之际,我校生物教师就抽出一定时间,分批组织初一、二年级学生中的生物爱好者和班干部,步行前往附近的农科所参观学习。在往返的路上,教师引导学生观察路边、田埂上丛生的杂草,学习识别和采制植物标本的方法;配合捕捉昆虫,指导学生观察风媒花和虫媒花形态结构上的特征和对传粉方式的适应。到达目的地后,首先带学生参观农科所内栽培的观赏植物。由于这些植物中多数是本地没有的种类,开阔了
In the past few years, our school has paid great attention to the utilization of local conditions and actively conducted biological extra-curricular activities to guide students in learning biological knowledge through various channels and achieved remarkable results. One of the main activities is to visit the Regional Agricultural Institute. Whenever the blossoms bloom in spring and summer, our biology teachers take a certain amount of time to organize the first-year and second-year students in biological enthusiasts and class cadres, walking to the nearby Agricultural Institute visited the study. On the way back and forth, the teacher guides the students to observe the weeds on the roadsides and fields, learn ways of identifying and collecting the plant specimens, cooperate with the catching insects to instruct the students to observe the morphological features of the windflowers and the insect flower, adapt. After arriving at the destination, first of all, take the students to visit the ornamental plants cultivated in the Agricultural Science Institute. As most of these plants are native species, they are wide open
