一、开门见山
在如今这个科技如此发达的时代,我们是否应该更多的了解科技?或者自己动手制作一些有趣的科技小物件?那么今天我们来教大家一款小学生科技小制作——飞行器。(飞行器图片)
最简单的科技小制作 二、需要什么材料
1.做飞行器的简易飞盘;
2.铝箔纸;
3.纸质卡片;
4.塑料杯
三、步骤详解
1.将做飞行器的简易飞盘倒放在桌子上,将铝箔纸晾开并铺在盘子里,慢慢将铝箔纸铺平,确保不留任何皱折和气泡。
2.将卡片切成3*4的小块,下方留半公分的空隙即可。
3.将小卡片放到铝箔纸上的1/3处,中心轻轻按压,让小卡片紧紧贴附在铝箔纸上面。
4.将塑料杯翻过来,看到杯口处有许多较小而坚硬的起点。将铝箔纸贴到这些起点上,使其固定。
5.将铝箔纸到平的一侧向杯子的中心处盘绕,直到将要盘绕到中心点的时候,重新将卡片轻轻按压,确保它不会掉落。
6.将卡片中的1/3再向杯子的中心点盘绕,确保卡片不会掉出来。
7.然后再将剩余的铝箔纸缓慢拼接在一起,用手指轻抚铝箔纸的表面,使铝箔纸几乎没有气泡和皱折。
8.当有足够大的空间来进行下一步的粘贴之时,可以使用双面胶进行粘贴,并且再次确定一下纸和卡片是否牢固,这样,飞行器的主体就制作成功了。
9.最后,使用另一个卡片剪出一些小小的,形状相同的三角形(大约三个左右),并且粘贴在飞行器的上端,以增加它的耐风性。
飞行器的制作就完成了,接下来就是驾驶它飞翔的时候啦。
四、注意事项
1.在制作的过程中,注意卡片粘贴位置,一定要切记将卡片紧贴。
2.粘贴的双面胶一定要够粘稠,这样才不会出现遗漏的情况。
3.要确保飞行器的平衡能够恰到好处以保证正常的飞行和运行。
五、制作成果展示

六、走出课堂,走向大自然
飞行器的出现,让我们因为它的精益求精和敏捷性而另眼相看,纷纷走出课堂,走向大自然。我们可以在户外飞行小飞行器,享受阳光和自然的凉爽,更可以在这种亲眼看到飞行器飞起来的乐趣中学习到更多关于物理学的知识。
七、遇到问题怎么解决
在制作中,如果遇到一些无法解决的问题,可以请教父母或者老师进行咨询和帮助,也可以在同学间提出讨论,共享经验,得出正确的解决方法。
八、小结
这次制作飞行器,给我们带来了很多的乐趣并且学习到了更多的科学知识。希望大家可以继续走出课堂,在生活中不断地探索和尝试,用自己的双手创造更多的科技小制作,让我们在科技的进步中共同成长。

【Main Text】
I. Get straight to the point
In this era of highly developed technology, should we know more about technology? Or make some interesting little technological objects by our own hands? Then today we will teach you a small science and technology production for elementary school students - flying objects. (Picture of flying objects)
II. What materials are needed
1. Simple flying disc for making flying objects;
2. Aluminum foil;
3. Paper card;
4. Plastic cup
III. Step by step
1. Put the simple flying disc for making flying objects upside down on the table, spread the aluminum foil and lay it in the plate, slowly flatten the aluminum foil, making sure no wrinkles or bubbles remain.
2. Cut the card into small pieces of 3*4 and leave a half centimeter of space below.
3. Put the small card on 1/3 of the aluminum foil, press it gently in the center to make the small card stick tightly on the aluminum foil.
4. Turn the plastic cup upside down, and there are many smaller and harder starting points at the mouth of the cup. Stick the aluminum foil to these starting points to fix them.
5. Coil the aluminum foil to the center of the cup with the flat side of the aluminum foil, until it is about to coil to the central point, and gently press the card again to ensure that it will not fall.
6. Coil 1/3 of the card to the center of the cup, making sure the card doesn't fall out.
7. Then slowly splice the remaining aluminum foil together, and gently rub the surface of the aluminum foil with your fingers to make the aluminum foil almost without bubbles or wrinkles.
8. When there is enough space for the next paste, double-sided tape can be used for pasting, and once again, make sure that the paper and card are secure so that the body of the flying object is made successfully.
9. Finally, cut some small, similarly shaped triangles (about three) out of another card and stick them to the top of the flying object to increase its wind resistance.
The flying object is made, and then it's time to fly it.
IV. Precautions
1. Pay attention to the location of the card paste during the production process and make sure to stick the card tightly.
