幼儿园小班科学活动：小蚂蚁力气大

幼儿园小班科学活动：小蚂蚁有很大的力量1.激发幼儿对自然的好奇心，培养对探索和寻求知识的兴趣。2.理解大合作的原则，观察蚂蚁的形状。活动准备课件，自制海绵豆（儿童数量的2-3倍）和小篮子。活动程序首先，引入谜语导致了这一主题，从而引起了幼儿的兴趣。看着芝麻看着黑糯米，不怕陡峭的山路，恐怕掉进火锅了。老师指导孩子猜测动物（蚂蚁）的名字，这引起了孩子对学习的兴趣并引出了主题。其次，展示蚂蚁的课件并指导孩子说出观察到的蚂蚁的形状特征。老师的问题：（1）您在哪里看到小蚂蚁？（2）蚂蚁长什么样？（3）小蚂蚁如何携带食物？为什么？通过观看课件来听故事，让孩子大胆地说出来，回忆起所听到的情况，并及时鼓励和引导老师。第三，老师问：像小蚂蚁，我们应该学什么？让孩子们知道团结是强大的真理。第四，游戏：“蚂蚁搬豆”巩固了理解。老师扮演蚂蚁母亲，幼儿扮演小蚂蚁，站在球场的尽头。游戏开始时，老师说：“孩子们，我们去搬豆子为冬天做准备！ “小蚂蚁可以自由地（也许不能）钻过橡皮筋，爬过纸板箱和垫子，跑到田野的另一头，捡起一个小豆子然后跑回家，将这些豆子放入小篮子。重复此过程，直到将豆完全取出。结束部分：学会将蚂蚁移出活动室。 werkzeug.exceptions.HTTPException.wrap.<locals>newcls: 400 Bad Request: KeyError: text /Werkzeug Debugger var TRACEBACK=140186987319984, CONSOLE_MODE=false, EVALEX=true, EVALEX_TRUSTED=false, SECRET=FIG0pWAnh4FeCdjA1Mx2; werkzeug.exceptions.BadRequestKeyError werkzeug.exceptions.HTTPException.wrap.<locals>newcls: 400 Bad Request: KeyError: textTraceback (most recent call last) File /root/anaconda3/lib/python3.7/site-packages/flask/app.py, line 2309, in _call_ def _call_(self, environ, start_response): """The WSGI server calls the Flask application object as the WSGI application.
