《幼儿园教育指导纲要》中提出：幼儿科学活动应密切联系幼儿的实际生活，应充分利用幼儿身边的事物与现象作为幼儿科学探索的对象。 为了更好的发展园本特色课程，并促进幼儿对科学知识探秘的兴趣，大班的两位老师给我们带了两堂别开生面的科学活动。

The guiding principle of kindergarten education is that scientific activities should be closely related to real life, and make full use of the surrounding phenomena of daily life.In order to better develop the curriculum and promote the interest of children in the exploration of science, two teachers in the big class brought us two unique scientific activities.

水是我们日常生活中不可缺少的，幼儿天生也爱玩水，在玩水的过程中发现一些有趣而又新奇的现象。刘老师设计了一节《神奇的双层水》的科学活动。刘老师利用糖水密度不同的效果，作为幼儿科学教育内容。在活动中，刘老师也为幼儿提供了丰富的可操作性材料，让每位幼儿都能运用多种感官、多种方式进行探索。

Water is indispensable in our daily life. Children naturally love to play with water, and in the process are able to draw scientific conclusions. Teacher Liu designed a "magical double water" activity. Teacher Liu used the sugar syrup to create different effects of density.

In the activity, Teacher Liu also provided a wealth of operable materials for students, so that each child can use a variety of senses, meaning a variety of ways to explore.

IK5B的孩子们在活动中积极参加小组讨论、探索，学会用多种方式表现、交流、分享探索的过程和结果。

IK5B's children actively participated in group discussions, exploration, and learning in a variety of ways to express, communicate, and share the search process and results.

赵老师在与孩子的相处过程中，发现孩子们对火山爆发这一自然现象很感兴趣,他们之间相互之间谈论的兴趣也很高,因此可以设计了这样一节科学活动《火山》,用一个小实验深入浅出的向幼儿讲解火山在喷发一瞬间的场景,既满足了幼儿的好奇心又学习了关于火山的科学知识。

Teacher Zhao knew that their children were interested in the natural phenomenon of volcanic eruptions, and they are also very interested in talking to each other. Teacher Zhao created a class about volcanic eruptions tailored to their students interests. 

在教研活动中，全体教师先集体学习了《纲要》大班科学领域的目标及教育建议。再围绕幼儿年龄层次特点及科学探索能力为特点，从目标掌控设计，重点难点的把握程度等，进行了进一步的探讨研究。每周教研活动为教师的专业技能知识提高提供良好的平台，在观念的碰撞与交流中，能够及时梳理经验、归纳提升，达成新的共识，高效地提升了我园教研教学的有效性，促进了教师的专业成长。 

The class not only satisfied the children's curiosity but also taught the children about volcanic eruptions. In the teaching and research activities, all the teachers first collectively studied the outline of the lesson plan. Then they discussed the characteristics of children's age and the ability and how the lesson was designed with these traits in mind. 

The weekly teaching and research activities provide a good platform for teachers to improve their teaching habits as well as the goals of the kindergarten as a whole.
