水面上的硬币在研究物体的浮沉条件时，有个同学无意中发现了一个有趣的现象：把一塑料尺子竖放(或侧放)在水面时，发现尺子迅速下沉了；而当他把尺子平放在水面时，即可发现尺子漂在水面上。 竖放(或侧放)尺子在水面上时，尺子下沉，是由于尺子所受的浮力小于它自身的重力而引起的；那又为什么在平放尺子时，它却是漂浮在水面上，若按物体的浮沉条件，物体漂浮时浮力可是等于重力的呀。这两者岂不自相矛盾了吗?问题症结在哪里呢? 在高中物理教材第一册“固体和液体的性质”一章中，有一个小实验：要求学生用棉纸把缝衣针垫起放在水面上，当棉纸被水浸湿下沉后，观察现象并说明原因，很多同学认为缝衣针浮在水面是由于液体表面张力作用的原因，以为针受重力、浮力和液体表面张力三者相平衡而使针能漂在水表面上。 那么就让我们先来认识一下液体表面张力吧。 什么是液体的表面张力呢? 液体表面附近的分子由平衡位置向外运动时，因为外部空气和蒸气分子对它的斥力很小。不起显著作用。它只受到内部分子的吸引力，因此使它恢复到平衡位置的作用力就没有在液体内部时大，使得表面层里的分子振动的振幅要比液体内部分子的振幅大，一些动能大的分予就可能冲出吸力范围，成为蒸气分子，结果形成表面层里的分子分布比液体内部的分子分布稀疏，分子之间的距离就比较大(r>r0)、正是由于液面分子分布较内部稀疏，分子间距r>r0，分子间引力占优势而产生了液体表面张力，由此可知，液体表面的张力实质是分子间相互作用的合力，它指向液体内部，可见托起硬币的力不可能是液体表面张力。那么让我们再来看看浮力吧。 先让我们先做一个实验： 在一盛有水的烧杯的水面平放一张滤纸，把一枚面值一角的硬币平放在滤纸上，待滤纸被浸湿而下沉后，发现硬币仍漂在水面上。注意观察硬币周围会发现水面向下凹陷，而硬币并未浸入水中，只是漂在水表面上。由此可见，此时硬币并未受到浮力作用。那是什么力与重力相平衡而使硬币漂在水面上呢? 由上一实验现象可知，水面向下凹陷，发生了形变，从而产生了一个与形变方向相反的弹力——支持力，这就如在一个吹气的气球上放上一个物体，由于物体的重力而使气球形变(向下凹陷)，而产生了竖直向上的支持力一样。是这个与重力大小相等、方向相反的支持力使硬币漂在水表面上。( 上面几个实验中的塑料尺子、缝衣针漂在水面上与此相同 ) 为什么侧放或竖放尺子、缝衣针以及硬币时，它们都将沉到水底呢?我们还是以硬币为例，当它侧放或竖放时，液面的受力面积很小，压强很大，压力作用效果显著；这与穿高跟鞋踩在沙地，鞋跟将陷入沙中一样，硬币陷入了水中，从而打破了水面的弹性形变，使水表面对它的支持力不复存在。此时硬币只受浮力和重力作用，而由于重力大于浮力，所以硬币很快就下沉到水底了。而平放时，对水面压强很小，就不会发生上述现象，而使硬币浮在水表面上保持平衡。在自然界中，也有许多相类似的现象。有些小昆虫可以在水面上跑来跑去或停留在水面上，不致于陷入水里，也是同样的道理。

一、研究性学习的背景及特点 从20世纪80年代末开始，世界各国开始对本国的教育系统作重大改变，教育改革的一个基本点和共同点集中在如何使本国的青少年具备21世纪所需要的“关键能力”，即用新技术获取和处理信息的能力、主动探究能力、分析和解决问题的能力、与人合作及责任感、终生学习的能力等。要培养这些能力，仅靠传统的学科和原有的学习方式显然不行。于是，project--based learning或project learning，(我国称之为“研究性学习”)，应运而生。研究性学习是20世纪80年代末以来国际教育界比较普遍推崇和实施的一种新课程。这种课程源于美国，自20世纪80年代杜威提倡“新教育”以来，美国中小学始终比较强调学校与社会、教育与生活的联系，强调学生自主地探究学习。1996年美国国家科学院推出的《国家科学教育标准》明确指出，科学探究是科学教育的核心，学校教育要把科学探究作为获取知识和认识世界的一种方法，突出了学生主动探究的学习在整个教育中的地位和作用。其他国家也在这方面表达了相同的认识。 什么是研究性学习?从广义理解，研究性学习泛指学生主动探究的学习活动，它是一种学习的理念、策略、方法，适用于学生对所有学科的学习。从狭义看，作为一门独立的课程，研究性学习指在教学过程中以问题为载体，创设一种类似科学研究的情境和途径，让学生通过自己收集、分析处理信息来实际感受和体验知识的生产过程，进而了解社会，学会学习，培养分析问题，解决问题的能力和创造能力。 研究性学习的核心是要改变学生的学习方式，强调一种主动探究式的学习，是培养学生创新精神和实践能力、推行素质教育的一种新的尝试和实践，与现有的学科相比，它有以下特点： “问题”(或专题、课题)是研究性学习的载体，整个课程主要围绕着问题的提出和解决来组织学生的学习活动 在研究性学习活动中，指导者通常不是提供一篇教材，让学生理解、记忆，而是呈现一个需要学习、探究的问题(专题或课题)。这个问题可以由展示一个案例、介绍某些背景或创设一种情景引出，也可直接提出；可以由教师提出，也可以引导学生自己发现和提出。 开放性是研究性学习在内容选择上的主要特点 在研究性学习中，问题多来自学生生活着的现实世界，内容涉及的面可以相当广泛教材、校园以外的各种教育资源，学生学习途径、方法不一，最后研究结果的内容和形式各异，它必然会突破原有学科教学的封闭状态，把学生置于一种动态，开放、主动、多元的学习环境中。 研究性学习过程主要由学生自己负责完成 研究性学习强调以学生的自主性，探究性学习为基础，在确定研究性学习的内容后，通常采用学生个人或小组合作的方式来进行，整个课程的内容、方式、进度、实施地点，最后的表现形态主要取决于学生个人或学生小组的努力。学生在老师的指导下，在规定的时间内，成为某一个研究课题的提出者、设计者、实施者，他对课程目标的达成负有主要的责任。 综合性、社会性和实践性是研究性学习内容组织时应重视的几个方面 综合性即围绕某个专题组织多方面或跨学科的知识内容，以利于知识的融合贯通和多角度、多层面的思考问题；社会性即加强理论知识与社会生活实际的联系，特别关注与人类生存、社会发展密切相关的重大问题，注意开发社区资源；实践性即在学习间接经验的同时，提供学习直接经验并在探究实践中获得积极情感体验的途径与机会。二、研究性学习设计 语法教学中的研究性学习 现行的高中英语教学中语法知识多以直接描述的方法呈现，且同一知识点分散于几个单元，这种编排虽体现了循序渐进、高复现率中加深印象的教学方法，但接触时对学生的不求甚解便可的要求无疑加重了学生的机械记忆的负担，从而减弱学生学英语的兴趣。语法是有规律性的东西，采用研究性学习让学生根据已有的初步知识自己去总结规律，在这一过程中再发现、再创造，从而培养学生的创新能力和问题意识。在教学中，教师应采用学生感兴趣的素材，尽可能多地从启发诱导入手，设计一个个有梯度、有意图的问题、逐步引导学生去归纳总结出语法知识。学生归纳正确，给予肯定，增强学生的自信心；学生归纳不正确时，分析原因，指明正确的用法，让学生在“原来如此”的情感体验中加深对此语法知识的理解与记忆；学生归纳之后，教师再给予相应的操练，以期收到触类旁通和巩固的效果。 以学习倒装为例，我采用以下步骤： 创设情景，提供材料(在幻灯片上打出下列句子) ①Here comes the The bus comes ②Out rushed the The children rushed ③LiLei rushed So did LiM LiLei rushed So LiMing rushed out ④Only then did he realize that he forgot his He realized that he forgot his bag only 出示问题：请学生仔细观察句子，分析每组句子的异同。 学生研读每个句子后，可得出如下结果：每一对句子意思都相同，但语序不同；每组的前一句都是倒装句型。(若学生首次碰到，可由教师直接告知)教师设问：何为倒装?学生归纳倒装的共性(主谓颠倒)。在学生对倒装有一定的认识之后，引导学生找疑问： Q1：倒装的作用是什么? Q2：倒装句都一样吗? Q3：在什么情况下需要倒装? 让学生把每组句子的第一句连成文章，请学生比较异同，从而回答Q1；请学生对比14两组句子，引导学生回答Q2，再观察每组句子，并且让学生研读教材上提供的例句，让学生分组讨论、总结，然后以小组为单位发言，从而回答Q3。在完成对这三个问题的回答之后，倒装作为一语法知识便已轮廓清晰、重点鲜明地凸现在学生面前。在学生归纳分析过程中，教师适当讲评、补充。这一过程始终让学生处主导地位，教师只起指导作用。 在语法教学的研究性学习中，教师应始终用问题的提出引导学生步步进入语言规律的认识，提供的素材应力求贴近学生实际富有趣味性。 总之，在高中英语教学中，本着研究性学习的特点，教师应用多尝试以问题为载体，引导学生的思维；始终以学生为主体，多创设各种合作学习的活动，让学生在讨论、合作、探究、体验中锻炼思维，培养学生学英语的兴趣和自信心，让学生在提高听、说、读、写能力的同时，养成自主学习和创新意识，从而为成为二十一世纪的主人奠定基础。

科学小论文范文（一）：月食是一种特殊的天文现象　　月食是一种特殊的天文现象，当月球运行至地球的阴影部分时，在月球和地球之间的地区会因为太阳光被地球所遮闭，就看到月球缺了一块。也就是说，此时的太阳、地球、月球恰好或几乎在同一条直线地球在太阳与月球之间，因此从太阳照射到月球的光线，会被地球所掩盖。以地球而言，当月食发生的时候，太阳和月球的方向会相差180度。古代月食记录有时可用来推定历史事件的年代。中国古代迷信的说法又叫做天狗吃月亮。月食可分为月偏食、月全食及半影月食三种。当月球整个都进入本影时，就会发生月全食；但如果只是一部分进入本影时，则只会发生月偏食。月全食和月偏食都是本影月食。　　在月全食时，月球并不是完全看不见的，这是由於太阳光在透过地球的稀薄大气层时受到折射进入本影，投射到月面上，令到月面呈红铜色。视乎月球经过本影的路径及当时地球的大气状况，光度在不一样的月全食会有所不一样。　　有时月球并不会进入本影而只进入半影，这就称为半影月食。在半影月食发生期间，月亮将略为转暗，但它的边缘并不会被地球的影子所阻挡。但是看月全食务必在晚上看，而且观看月食的机率比日食的机率少的多。　　关于月食，还有一个故事：16世纪初，哥伦布航海到了南美洲的牙买加，与当地的土着人发生了冲突。哥伦布和他的水手被困在一个墙角，断粮断水，状况十分危急。懂点天文知识的哥伦布明白这天晚上要发生月全食，就向土着rnd喊，再不拿食物来，就不给你们月光！到了晚上，哥伦布的话应验了，果然没有了月光。土着人见状诚惶诚恐，赶快和哥伦布化干戈为玉帛。　　科技小论文范文（二）：科技改变生活　　科技改变生活，时代在渐渐发生变化，科学在不断进步。科技的发展，给我们的生活带来了许多便利，我们的生活与科技息息相关。　　在以前，农民伯伯每到春天，就要辛辛苦苦的进行插种，播种等的工作，夏天又要杀虫，秋天又要忙着收获，跟着种其他农作物。他们要一年四季，这样每一天重复着同样的顺序，天天佝偻着背下地干活，经常弄得自我筋疲力尽。可有时候天气会喜怒无常，下几场大雨或连续几天的干旱，再加上某些地方环境的污染严重，害虫随处可见，这些足以让农作物无法生长，农民辛苦的劳动得来的却是落得一场空。　　此刻，随着科技的发展，带来了一种新的培育方式太空育种。它是搭载科学实验的一种，是将农作物种子搭载于回到式地面卫星，借助太空超真空微重力及宇宙射线等地面不可模拟的环境变化，使种子发生变异，经过地面多代选育获得稳定的遗传性状，从而培育出新的农业品种来。　　自1987年以来，我国科学工作者利用回到式地面卫星，先后进行了多种植物的空间搭载实验，培育出了一系列高产、优质、多抗的水稻、小麦、番茄、青椒、芝麻等作物的新品种。太空育种已得到必须程度的应用，从太空的带来的果实，它的重量和外形都发生了变化，比在陆地上培育的果实要大得多，好吃得多。　　科学之门已经打开，科技带给我们的便利随处可见，以后科技的发展，还需要我们来探索，来创造。让我们插上科学的翅膀，在科学世界里自由地遨游，发现并探索我们生活中的科学，为未来的科技贡献我们的一份力量。（以上两篇600字的科技小论文范文均来源于学术堂）

中学生科技论文范文1：树干为什么是圆的 在观察大自然的过程中我偶然发现，树干的形态都近似圆的——空圆锥状。树干为什么是圆锥状的?圆锥状树干有哪些好处?为了探索这些问题，我进行了更深入的观察、分析研究。　　在辅导老师的帮助下，我查阅了有关资料，了解到植物的茎有支持植物体、运输水分和其他养分的作用。树木的茎主要由维管束构成。茎的支持作用主要由木质部木纤维承担，虽然木本植物的茎会逐年加粗，但是在一定时间范围内，茎的木纤维数量是一定的，也就是树木茎的横截面面积一定。接着，我们围绕树干横截面面积一定，假设树干横截面长成不同形状，设计试验，探索树干呈圆锥状的原因和优点。　　经过实验，我们发现：(1)横截面积和长度一定时，三棱柱状物体纵向支持力最大，横向承受力最小；圆柱状物体纵向支持力不如三棱柱状物体，但横向承受力最大；(2)等质量不同形状的树干，矮个圆锥体形树干承受风力最大；(3)风是一种自然现象，影响着树木横截面的形状和树木生长的高矮。近似圆锥状的树干，重心低，加上庞大根系和大地连在一起，重心降得更低，稳度更大；(4)树干横截面呈圆形，可以减少损伤，具有更强的机械强度，能经受住风的袭击。同时，受风力的影响，树干各处的弯曲程度相似，不管风力来自哪个方向，树干承受的阻力大小相似，树干不易受到破坏。　　以上的实验反映了自然规律给我们启示：(1)横截面呈三角形的柱状物体，具有最大纵向支持力，其形态可用于建筑方面，例如角钢等；(2)横截面是圆形的圆状物体，具有最大的横向承受力，类似形态的建筑材料随处可见，如电视塔、电线杆等。 　　在我的观察、试验和分析过程中，逐渐解释、揭示了树干呈圆锥状的奥秘，增长了知识，把学到的知识联系实际加以应用，既巩固了学到的知识，又提高了学习的兴趣，还初步学会了科学观察和分析方法。范文2：皮鞋为什么越擦越亮每到星期天，我总要完成妈妈交给我的擦鞋任务。告诉你，这可是我一星期零花钱的来源哦!拿到沾满灰尘的皮鞋后，我先把鞋面的灰尘擦掉，然后涂上鞋油，仔仔细细地擦一擦，皮鞋就会变得又亮又好看了。可这是为什么呢　　我找了同样牌子同样款式的新旧两双皮鞋进行对比观察。我先用手触摸两双皮鞋的鞋面，发现新皮鞋的表面比旧皮鞋的表面光滑得多。旧皮鞋涂上鞋油，仔细擦过后，虽然亮了许多，但仍无法与新皮鞋相比。皮鞋的亮度是否与鞋面的光滑程度有关呢?　　我取来一双没擦过的旧皮鞋，在放大镜下鞋面显得凹凸不平的。然后，我再在皮鞋上圈出两块表面都比较粗造的A区和B区，A区涂上鞋油并仔细擦拭，B区不涂鞋油作空白对照。我发现A区擦拭后，表面明显变光滑了许多，而且放在阳光下也比B区有光泽。为什么两者会产生这样的差别呢?　　我想到在物理课上老师曾经讲过：影剧院墙壁的表面是凹凸不平的，这样可以使声音大部分被吸收掉，让观众不受回声的干扰。同样道理，光线照到任何物体的表面都会产生反射，假如这个平面是高低不平的，光线就会向四面八方散射掉；假如这个平面是光滑的，那么我们就可以在一定的方向上看到反射光。　　皮鞋的表面原来就不是绝对的光滑，如果是旧皮鞋，它的表面当然更加的不平，这样它就不能使光线在一定的方向上产生反射，所以看上去没有什么光泽。而鞋油中有一些小颗粒，擦鞋的时候这些小颗粒正好可以填入皮鞋表面的凹坑中。如果再用布擦一擦，让鞋油涂得更均匀些，就会使皮鞋的表面变得光滑、平整，反射光线的能力也加强了。　　通过实验，我终于知道了皮鞋越擦越亮的秘密啦!范文3：醋对花卉有什么影响醋是生活中常用的调味品，花卉则能净化生态环境，并美化我们的生活。　　你是否想到过，醋和花卉有什么关系呢?我们怀着好奇心，开展了这个课题的探究。据富有种花经验的人告诉我们，对盆栽花卉施些醋溶液，可改善盆花的生长，增加花朵，而且花艳叶茂。这一点我们在实验中很快就证实了。　　浓度不同的醋溶液，对花卉有不同的影响吗?这是我们第二阶段的实验。我们选取长势相同的满天星、报春花、月亮花各四盆，分为四组，每组（三盆）各有三种花卉，分别编号、贴上标签。同时，我们取食用白醋配制成1％（pH值为2~3）、0．01％（pH值≈4）、0．0001％(pH值≈6)三种浓度不同的溶液，每天分别给三组盆花固定喷洒一种醋液，第四组盆花洒不含醋的清水。每五天观察记录花卉的生长情况。　　这项实验的结果是：喷洒低浓度醋液(pH值≈6)对这几种花卉没有明显影响；喷洒中等浓度醋液（pH值≈4）的花卉明显长得比其他几组好，花苞多，开花期提前，而且花色较浓艳，花期也延长了；喷洒pH值2－3的高浓度醋液后，反而使花朵过早凋萎。　　通过这次实验，我们可以告诉你：种花时适当喷洒一些醋液，可使花卉长得更好。不过要掌握好醋液的浓度，醋酸过浓则会伤害花卉。
