Nam sinh lớp 7 chế tạo thành công đèn bắt côn trùng

Nam sinh lớp 7 chế tạo thành công đèn bắt côn trùng

Sau thời gian mày mò nghiên cứu, em Nguyễn Duy Long (13 tuổi, học sinh lớp 7, Trường THCS Lương Thế Vinh, huyện Chơn Thành, tỉnh Bình Phước) đã sáng tạo thành công mô hình “đèn bắt côn trùng”.

Duy Long chia sẻ: “Thấy ông bà ngoại và bố mẹ phải vất vả với ruồi muỗi mỗi khi trời mưa xuống, vả lại khi học bài em cũng hay bị ruồi muỗi bu đến quấy rầy, từ đó em mày mò chế tạo ra đèn bắt côn trùng từ cây vợt đập muỗi sẵn có.

Mô hình đèn bắt côn trùng của em Duy Long

Lúc bắt tay vào làm, mẹ em đã tốn rất nhiều cái vợt muỗi vì em làm không thành công, nhưng em không nản chí và sau nhiều lần nghiên cứu cuối cùng em đã chế tạo thành công mô hình”.

Duy Long cho biết, vật liệu để làm đèn bắt côn trùng gồm: vợt bắt muỗi, bình khô, cục sạc điện, 2 công tắc điện, 2 đuôi đèn + 2 bóng đèn, hộp gỗ vuông…

Cách làm, dùng vợt điện mua sẵn đem nối vào bình khô (bộ phận tích điện 6V), rồi nối 2 đuôi đèn để thắp sáng bóng điện nhằm dẫn dụ côn trùng bay tới.

Kế đến, cho nối 2 công tắc điện (một công tắc điều khiển 2 bóng đèn và một công tắc điều khiển hệ thống lưới điện bắt côn trùng), sử dụng với dòng điện 220V. Sau đó, cho vào một hộp gỗ hình vuông có kích thước khoảng 20cm nhằm làm khung giá đỡ cho vợt bắt côn trùng.

“Vào ban đêm khi mở hệ thống ánh sáng đèn điện lên các côn trùng sẽ bay tới, gặp vợt điện ngay lập tức côn trùng sẽ bị tiêu diệt. Mô hình này còn có tác dụng làm đèn để học bài vào ban đêm, giúp tiết kiệm điện năng” – em Duy Long nói.

    RBNovember 13, 2012 Overall: Flavor Vapor Shipping Value I ordered my first Starter Kit and received it fairly fast. I believe I received a faulty battery, so I do not think I have experienced the full vapor yet, kind of bummed out about that, because I’m still buying cigarettes. They are sending me a new battery and I also purchased a manual battery as backup, which it’s on its way as well. I’m really hoping to get the experience that everyone else has had with V2. I will post again once received.

    ¿Tienes el morro de poner un enlace de una obra de la que no tienes los derechos, para que la gente se la puede descargar gratis, y dices que no eres un pirata? Y encima te quejas de que hayan bloqueado el blog.

    True enough, power is the final answer. Of course, rent seeking behavior is also corruption even by your definition. It is, after all, through a deception that people believe they have property rights. And without property rights, all other rights are meaningless. So what does all this mean to me? Just that it is useful to see things clearly. I don’t have any power over the weather, so I just deal with whatever comes my way. Turns out the same is true of government.

    hehe Am besten erstmal die komplette Seite lesen und dann fragen. Eigentlich sollte aus dem Text hervorgehen, dass die komplett selber zusammengeauft ist. Also die gibt es so nicht zu kaufen. Die Kosten habe ich nicht zusammengerechnet. Aber dadurch, dass ich alle verbauten Teile aufgelistet habe, kann das eigentlich jeder machen. Es sollten so um die 600€ sein. Werde sie aber noch ändern. Bin noch nicht ganz zufrieden.

Although, when faced with all that walking, I can see your point. Big time luck on your next attempt. I have a feeling this will be the charmed one.

    辛口、失礼します。書かれてないのですが、専業主婦でらっしゃると理解していいんでしょうか?その前提で書きますが、違っていましたら、失礼します。家事、育児は自分の仕事。勤務して報酬を得てくるのが夫の仕事。ひと先ず、そう考えて見られたらいかがでしょう?家事・育児分担と言われますが、「やってくれて当たり前、してくれなくてひどい。私は被害者だ。」というスタンスは違うんじゃないかな?と感じました。非難する雰囲気がプンプンしてたら、ご主人はますます動きませんよ。「子育て中で、私はキャパオーバー」て看板をでかでかと掲げるのって、評価を下げます。「子供の調子が悪くて、家事が進まなかったの。ここまでは頑張ったけど、至らなくてごめんね」て言ったほうが、同じ状況でも、ご主人にとっても、気分よく受け取れるんじゃないでしょうか。はっきり言って、一緒に出掛けてご主人の態度がストレスになるなら、無理に一緒に行くこともないんです。回数を減らせば、ご主人も気分よく付き合ってくれる可能性はないですか?て言うか、子供が公園で遊ぶ年になったらママ友もできて、パパ抜きで遊ぶ方法なんて、いくらでも見つかります。夫婦といっても、全てにおいて同じ目的で生きてるè¨Âme and effort you put into your blog and detailed information you offer!

    Being no fan of Obama administration, I do believe this article does unjustice to the truth, as after all, his administration inherited the financial crisis that previous American governements created. I am not sure that tightning the cashpresses would have been a better idea as traditionel economics say: spend in crisis and be frugal in a booming economy. It would have remained to be seen whether a republican administration would have found the magic cure out of this financial mess. Had they done what pure capitalism actually prescribes:letting the perpetrators of the crisis, the banks, go bust, what would have been the result?

I filled a prescription for a potent looking anti-inflammatory for the asthma attacks. I see the doctor again next week.Next Friday will be doctor day. I see a kidney specialist in the morning and my pulmonary specialist (the one treating my asthma) in the afternoon. I've decided to postpone the bulk of the grading for tomorrow
