师:很好。由于存在地球大气圈、地球水圈和地表的矿物,在地球上这个合适的温度条件下,形成了适合于生物生存的自然环境。人们通常所说的生物,是指有生命的物体,包括植物、动物和微生物。据估计,现有生存的植物约有40万种,动物约有110多万种,微生物至少有10多万种。据统计,在地质历史上曾生存过的生物约有5亿~10亿种之多,然而,在地球漫长的演化过程中,绝大部分都已经灭绝了。现存的生物生活在岩石圈的上层部分、大气圈的下层部分和水圈的全部,构成了地球上一个独特的圈层,称为生物圈。生物圈是太阳系所有行星中仅在地球上存在的一个独特圈层。课堂小结:地球所有的外部圈层是相互渗透、相互影响,甚至相互重叠的,在太阳和人类生活的参与下,整个地球生机盎然;同时,它们起着保护地球的作用,可以减弱太阳和宇宙辐射对地表的影响,减少宇宙中的陨石对地球表面的撞击。外部各圈中的物质运动和循环,是促使地表物质和形态演变的重要动力。
【转折过渡】除了以上所说的褶皱山和断层山之 外,是否还有其他类型的山脉呢?试举一例说明。【学生思考后回答】有,如富士山属于火山。【教师总结】同学们回答的很好,还有火山,那么火山是如何形成的呢?这就是我们要研究的下一个问题。【板书】3、火山【指导读书】请同学们阅读教材P81思考:①玄武岩高原和火山有什么联系与区别? ②火山由哪几部分构成的?③火山的规模是否相同?【学生回答】①联系:玄武岩高原和火山都是由于处于地下深处的岩浆,在巨大的压力作用下,有时候会沿着地壳的薄弱地带喷出地表而形成的。区别:玄武岩高原是岩浆沿着地壳的线状裂隙流出,往往比较宽广。如哥伦比亚高原。火山是岩浆沿着地壳的中央喷出口或管道喷出。如我国长白山的主峰。②火山由火山口和火山锥两部分组成。③火山的规模大小不一,大火山的相对高度可达4 000~5 000米,火山口直径为数百米;小火山的相对高度不及100米。
月球对地球的意义月球与地球形影相随,关系密切。月球对地球的影响,主要有以下几方面:1.地球上夜晚的自然照明,主要靠月亮。2.远在古代,人们就根据月相变化的周期,编订历法。我国农历月份的安排,是以月相变化 周期为标准的。农历规定朔为初一,这样,望就在十五日或十六日。我国人民的传统节日,像春节、中秋节就是按农历的月日计算安排的。3.由于地球表面各处所受月球和太阳引力的不同,地球上的水体产生了明显的潮汐现象。4.月球是人类星际航行的第一站。已知月球表面有多种宝贵矿藏;重力较小;没有大气层,利用太阳能的条件较好。如何利用月球的特殊环境,开发月球的资源,以及如 何利用月球作“码头”,使人类更好地研究宇宙,这将是月地关系的新篇章。
一般情况下,凡是支持物对物体的支持力,都是支持物因发生形变而对物体产生弹力。所以支持力的方向总是垂直于支持面而指向被支持的物体。例1:放在水平桌面上的书书由于重力的作用而压迫桌面,使书和桌面同时发生微小形变,要恢复原状,对桌面产生垂直于桌面向下的弹力f1,这就是书对桌面的压力;桌面由于发生微小的形变,对书产生垂直于书面向上的弹力f2,这就是桌面对书的支持力。学生分析:静止地放在倾斜木板上的书,书对木板的压力和木板对书的支持力。并画出力的示意图。结论:压力、支持力都是弹力。压力的方向总是垂直于支持面而指向被压的物体,支持力的方向总是垂直于支持面而指向被支持的物体。引导学生分析静止时,悬绳对重物的拉力及方向。引导得出:悬挂物由于重力的作用而拉紧悬绳,使重物、悬绳同时发生微小的形变。重物由于发生微小的形变,对悬绳产生竖直向下的弹力f1,这是物对绳的拉力;悬绳由于发生微小形变,对物产生竖直向上的弹力f2,这就是绳对物体的拉力。

重点难点1.欣赏和感知理解漫画作品.需要幼儿集中注意观察,这也是能否达到目标的重要条件。因此,我从活动开始便设置了一个个悬念,直到结尾也就是高潮部分,我没有直接揭晓答案,而是留给幼儿一个充分的想像空间。这样,使幼儿的注意得以长久保持。2.了解漫画特点对幼儿是有一定难度的,当然也不是一次活动所能完成的。因此,在活动中,我们不能空洞地将一些抽象的词汇灌输给孩子们听,而是通过精心设计的提问和让幼儿欣赏一些有代表性的漫画作品,有机渗透在活动中。我还设置了漫画墙作为准备和延伸活动,长期贴在教室里,使幼儿自己从中慢慢体会,不断深入地了解漫画。 活动目标1.理解漫画作品内容,尝试运用语言和图画刨编故事结尾。2.通过漫画欣赏、初步了解漫画的基本特点,更加喜欢漫画这一艺术形式。3.养成细致观察和大胆想像的习惯。 活动准备1.漫画书《父与子》一本,完整的4幅漫画作品、不加背景的图4一幅。2.供幼儿续编添画的作业纸每人一张、黑色水笔每人一根。3.布置一个漫画墙,上面贴有许多有代表性的漫画作品(单幅的、连环的、黑白的、彩色的、有趣可笑的、充满幻想的、讽刺褒贬的)。
【活动目的】1. 使学生明礼诚信,做一个诚实守信,言行一致的人。2. 锻炼学生组织活动的筹划能力、展示学生的表演才艺。【活动准备】1. 学生事先准备好有关诚实守信的相关书面材料2. 班长为本次主题班会的主持人,准备好相关讲稿。【活动过程】一、激情导入男:我们的祖国是一个有着悠久历史、灿烂文明的大国。女: 中华民族是一个勤劳、勇敢、智慧民族。男:在我们漫漫的人生路上,什么不可丢弃?女:在我们遇到艰难困苦时,什么要永留身边?男:它在我们身边,离我们是那样近;它又离我们越来越远,是那样模糊。女:它是我们远行路上的灯塔,指引着我们前行的方向。合:它就是我们人生路上的朋友——诚信!即诚实守信。男:什么是诚实守信呢?(学生交流:诚实意味着实事求是,表里如一,说实话,做实事,不虚伪,不夸大其辞。诚实的人,不说谎话,不会欺骗自己,同时也不欺骗别人,做事大大方方,不做违背良心的事,实事求是,言行一致,说到做到。)
一、引入 主持人:感谢父母,他们给予你生命,抚养你成人;感谢老师,他们教给你知识,引领你做“大写的人”;感谢朋友,他们让你感受到世界的温暖;感谢对手,他们令你不断进取、努力;感谢太阳,它让你获得温暖;感谢江河,它让你拥有清水;感谢大地,它让你有生存空间。感恩,是一种心态,一种品质,一种艺术。感恩是礼貌。有人帮助了我们,我们随口说声“谢谢”,可能会给对方心里带来一股暖流。有人为我们付出了许多,我们感谢他,他可能会更加多的帮我们。怀着感恩的心,是有礼貌,是知恩图报。所以,感恩,是一种有礼貌的品质。感恩是画笔。学会感恩,生活将变得无比精彩。感恩描绘着生活,将生活中大块的写意,挥洒得酣畅淋漓;将生活中清淡的山水,点缀得清秀飘逸;将生活中细致的工笔,描绘得细腻精美。所以,感恩,是一种多样的艺术。下面我宣布“让我们都有一颗感恩的心”主题班会现在开始!

活动准备 1、ppt课件,投影仪,电脑。 2、设置绘画区、拼贴区、泥工区、建构区、表演区,各个区提供相应的操作材料。 活动过程 1、欣赏建筑,感受造型的变化 (1)感受建筑物高低、方圆、形状等外形的丰富变化 ①引入:前段时间老师去外地旅游,发现那里的建筑可真漂亮,你们想去看一看吗?今天,杭老师把这些建筑的照片带来了,想和大家一起看看,好吗? ②播放课件出示建筑图片,让幼儿初步观察欣赏,感受建筑物的外形变化。 ③教师提问:你最喜欢哪一个建筑,它是什么样子的?在欣赏过程中,教师根据幼儿的回答用课件放大建筑图片,引导幼儿进行仔细观察,积极表达自己的发现。让幼儿发现建筑物有的是方方的、一层一层叠得很高;有的像一座塔,越高的地方就越细;有的是左右两边一样、是对称的;有的像一朵荷花……
活动准备:各种颜色、形状的卡通杯若干、彩色笔、蜡笔、图画纸若干张 活动过程:一、谈话法激趣。小朋友,天气炎热的时候,我们会口渴,口渴的时候会想要喝水。用什么装开水喝,用自己的杯子喝水是最卫生的。没有杯子的孩子也没有关系,通过这堂课的努力,我们会获得自己最喜欢的杯子的。二、展示若干漂亮的卡通杯。老师拿一只杯子让幼儿仔细的观察后,提问: 老师:孩子们,这是只——漂亮的卡通杯。想一想,说一说,杯子可以来做什么? 孩子会想到可以装水喝水,可以做屋子的点缀,可以用杯子装水漱口,还可以用保温的杯子装鸡汤等。杯子有这么多用处,你一定很想从这里面挑一只杯子吧。请小朋友们有序的来挑一只自己喜欢的杯子。看一看,你挑选的杯子的颜色、样式,摸一摸杯子,有什么样的触觉,想一想,我选的杯子与其他杯子有什么不同,和其他小朋友交流交流,说一说,我选择的杯子怎么认。
活动目标:l、通过游戏活动,发展幼儿走跑交替、跳跃及平衡的能力,体验游戏带来的乐趣。2、通过游戏活动,发展幼儿四肢的协调性、柔韧性和动作的灵敏性,提高幼儿听信号做相应动作的能力。3、培养幼儿的扩散性思维和协作能力。 活动准备:l、红、黄、蓝、绿色的塑料圈每人四个。2、红、黄、蓝、绿色的小旗各一面。3、大鼓一面,柱子两根。4、录音机、磁带。5、场地布置如图。
结合历史自古以来,江山美人历来都是引无数英雄豪杰竞折腰的,如果说英雄选择了美人却丢了江山,把所有罪名都归结于“女人是祸水”。但是,纣王无道,和有了妲己有必然的联系吗?有人说妲己坏透了,坏透了的妲己如果不是取得纣王的信任是坏不起来的,纣王听信了妲己的谗言,听与不听决定权在纣王,而不在妲己。强势永远在纣王一边。再来看看西施和杨贵妃:西施是作为越国贡献给吴国的供品来到吴王夫差的身边的,杨贵妃更是先是李隆基的儿媳妇被看中而得宠的。所以,西施和杨贵妃这两个可怜的女人根本没有自己的独立选择,没有独立的爱情,如果没有西施,就会有南施,或北施;如果没有杨贵妃,就会有李贵妃,王贵妃,总之什么施,什么妃是不能少的,因为那是吴王和李隆基的需要。

The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves. The motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them. The mission of wild aid is to ban illegal trade in endangered wildlife and mitigate climate change. It aims to educate the public to reduce the consumption demand for endangered wildlife products through public publicity and improve the awareness of environmental protection.1. Improve the awareness of wildlife protection by acquiring the knowledge of wildlife protection.2. Focus on environmental protection and protection of all lives.3. Analysis of the living environment of wild animals with appropriate thinking mode.4. Skillfully use the vocabulary and grammar knowledge of this unit to cultivate self-study ability according to the unit content5. Develop cooperative learning ability through discussion and other ways1. Enable the Ss to talk about the current situation of wild animals.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.
