自然教材中有许多关于动植物的知识,教师进行这方面知识教学时,需要有相应的观察和实验材料,如:各种各样的花、不同开头的根、金鱼、蜗牛、蚕等。有的动植物在仪器里是没有标本的,需要自然教师自己准备,但是像蚕、蜗牛等小动物不是一时可以找到的。所以,在自然教室里设置生物角就显得非常重要了。 Natural textbooks have many knowledge about animals and plants. When teachers carry out knowledge teaching in this area, they need observation and experimental materials such as various flowers, different roots, goldfish, snails and silkworms. Some animals and plants in the instrument is not specimens, natural teachers need to prepare, but such as silkworm, snails and other small animals can not be found temporarily. Therefore, it is very important to set the biological corner in the natural classroom.
