在科学活动“认识昆虫”之后,教师安排了美术活动,让幼儿画一只自己喜欢的昆虫。有的幼儿画了蜻蜓,有的幼儿画了七星瓢虫、蝴蝶……其中两名幼儿因画蝴蝶发生了争执。幼儿甲:“你画的蝴蝶不对,蝴蝶应该有四只翅膀,可是你只画了两只。”幼儿乙:“我就想给蝴蝶画两只翅膀,因为我觉得这样很漂亮,老师说画画的时候不分对不对,自己认为漂亮就行。”
科学和艺术是幼儿园课程的两大领域,但在教学实践中常常发生矛盾,你认为是应该告诉幼儿正确的科学知识呢?还是尊重幼儿的审美理解和表达?在教学实践中又应该如何处理两者关系?

Who invented tea?
Did you know that tea, the most popular drink in the world(after water), was invented by accident? Although tea wasn't brought to the western world until 1610, this beverage was discovered over three thousand years before that. According to an ancient Chinese legend, the emperor Shen Nong discovered tea when he was boiling drinking water over an open fire. Some leaves from a nearby bush fell into the water and remained there for some time. The emperor noticed that the leaves in the water produced a pleasant smell. Later he decided to taste the hot mixture. It was quite delicious. And in this way, one of the world's favorite drinks was invented.
