土豆是农村种养比较普遍的蔬菜植物,由于小学《科学》课安排有土豆沉浮与淀粉测试实验,《劳动技术教育》课又涉及到植物的种养,刚巧我校有一块劳动园地分配到五、六年级各班,于是,我们组织学生开展了“土豆种植形式与收获时间的比较实验”活动。让学生亲历土豆生长的全过程,探究土豆不同的催芽方法、不同的播种形式与收获时间的关系,既让学生学习土豆的种养技术,传承农耕文化,又自力更生,为《科学》课堂教学准备好充足的实验材料,实现了劳技实验探究与《科学》课实验材料采集双丰收。
Potatoes are the most common vegetable plants in rural areas. Due to the arrangement of potato ups and downs and starch test in the “science” class of primary schools, “labor and technical education” also involves planting and breeding of plants. It happened that I had a labor garden allocated to five , Sixth grade classes, so we organized the students to carry out the “potato planting forms and harvest time comparison experiment” activities. Let students look through the whole process of potato growth and explore the different methods of potato germination, different sowing forms and harvest time, both for students to learn potatoes planting and breeding techniques, heritage farming culture, and self-reliance, for the “science” classroom teaching preparation Good enough experimental material, to achieve the labor technology research and “science” class experimental materials acquisition double harvest.
