建立减数分裂中染色体变化的模型是人教版高中生物必修2第2章第1节模型建构中的内容,学生通过制作减数分裂中染色体变化的模型,可体验动手制作的过程和小组合作的重要性,强化对减数分裂中染色体变化规律的理解。在这里介绍一种使用卡纸和磁铁等简易材料建立减数分裂中染色体变化模型的方法。一、材料用具材料:红色和黄色卡纸,磁铁(直径约为1.0~1.5cm),纸张。用具:剪刀,铅笔,直尺,透明胶带,壹圆硬币(或圆规)。
The model for establishing chromosome changes in meiosis is the content of the model construction in Chapter 2 of Chapter 2 of the PEP Biological Biology. Students can experience the process of hands-on production and collaborate with the group by making models for chromosome changes in meiosis. The importance of strengthening the understanding of chromosome changes in meiosis. Here is a method to establish a chromosomal change model in meiosis using simple materials such as cardboard and magnets. First, material appliances materials: red and yellow cardboard, magnets (diameter of about 1.0 ~ 1.5cm), paper. Utensils: Scissors, pencils, rulers, scotch tape, round coins (or compasses).
