会说话的模型-七年级科学团队合作活动

　　阳光明媚的冬日，教室里同学们兴致勃勃地拿着各自制作的人体模型，摩拳擦掌准备上台大展身手。

　　On a comfortable day in December, the anticipated students of seventh grade excitedly held the models they made of the circulatory system for science class.

　　最近7年级的同学在科学课上学习了人体的血液循环系统。艰涩的专业词汇，复杂的身体结构，同学们不免有点头大。科学组的老师们好像看到透了我们的心思，组织我们进行了科学小组活动。本次小组活动要求各个小组运用不同的材料先做出一个完整的人体模型，再根据模型描述人体血液循环系统。

　　In the past few weeks, the students of grade seven were studying human blood circulation in science class. However, the professional vocabulary, complex body structures greatly confused the students. The teachers of the grade seven science department came up with an idea to solve this problem: organizing a project. The teachers required each group of students to use different materials, completing a full model of the human circulatory system. Finally, the students would have to present their projects through speaking.

　　课后，同学们马不停蹄地搜集资料，汇总，制作模型。大家就地取材，有的用黏土，有的用纽扣，还有的用不同颜色的毛线代表不同流向的血液。模型的形式也是各种各样，有的是一张图纸，有的是电脑模型，有的竟然大到能装下一个人。然而不管哪种模型，人体的血液循环都纤毫毕现。

　　After the introduction of this project, the students immediately began to prepare for it. They researched for extra information they could add, organized it, and at last, made the model. Every student used their creativity: some used clay to mold, some used buttons, and some even used woolen yarn to represent the different flows of blood. The forms of models were also various: some were papers, some were computer models, and some were large as a real-sized human. No matter the forms, the details of the model were always complete.

　　展示时间到了，有的小组派出一名代表上台演讲，有的全组一起分享。“体循环的基本过程是血液从心脏的左心室输出，经主动脉及其各级分支，到达全身各部分的毛细血管……”生动的模型和细致的讲解，让大家对血液循环系统的科学知识印象深刻。

　　When the time of presentation arrived, some groups elected a representative to lecture their classmates about their model. Some groups shared with the whole group. The basic flow of blood goes from the left atrium of the heart, passing the aorta, and arteries, arriving the capillaries..." Vivid posters and detailed explanations made a deep imprint on the students of seventh grade.

　　这些海报体现出了同学们探索科学的兴趣和努力，更让同学们大开眼界，去认识更多，了解更多，探索更多。

　　斯宾塞曾经说过：“科学是人们生活中最重要、最美好和最需要的东西。”希望大家能够永远保持一颗好奇的心，去继续发现更多关于世界的奥秘!

　　Throughout this activity, not only did everyone experience the joy of making models, but also reviewed their knowledge while they've been preparing. Science group projects like this arose the students' interest in science, and also matured our skills of exploring the attractive subject of science.
