歡迎閱讀《週日科學版》!我們每週日都要為你介紹可以在家中進行的有趣科學實驗。你可以在《科學日誌》中 記錄自己做了哪些活動,這樣就可以將所學的紀錄下來,比較這些結果,也許還可以利用它們來設計新的實驗!先看一下《科學日誌》的點子再開始吧。展開實驗之 前,記得要獲得大人許可喔!
This week we're going to make a paper dragonfly and a paper airplane. We're going to use these to demonstrate how helicopters, planes and even most birds are able to fly!
本週我們要來做紙竹蜻蜓和紙飛機,我們要利用這個機會來說明直昇機、飛機,甚至大多數鳥類的飛行原理!
What you will need:
Paper
Scissors
A paperclip
To make the paper airplane:
★ Take a look at the picture below. Fold a piece of paper in half lengthwise to make a center crease.
★ Unfold the paper. Fold the two upper corners of the paper to the center crease, and then fold the folded corners to the center crease.

★ Fold the paper in half again lengthwise, and then fold the two wings down.
To make the paper dragonfly:
★ Take a look at the picture to the right. You need to copy it on to a piece of paper. You can make it bigger if you like. Cut along the dotted lines and fold along the solid lines. First fold A and B down in different directions to make the paper dragonfly's blades. Next fold C and D over in opposite directions, and then fold E up and attach a paperclip to make a stable base.
Don't forget to record what happens in your Science Journal.

所需材料︰
紙
剪刀
迴紋針
紙飛機的製作步驟:
★ 參照下方圖示。將長方形紙「直立」對摺,中央會出現一條摺痕。
★ 把紙攤開,將上面兩個紙角摺向中央線,然後再將摺出來的折角摺向中央線。
★ 再把紙縱向對摺一次,然後把摺起的兩個機翼放下。
紙竹蜻蜓的製作步驟:
★ 參考右側圖示。你必須把圖示複印到一張紙上,你可以依個人喜好放大,然後沿著虛線剪開,再沿實線摺疊;先將A和B處朝不同方向摺下,做成紙竹蜻蜓的槳翼,然後將C和D處反摺交疊,最後將E處向上折起,再用一根迴紋針固定基底即可。
別忘了把結果記錄在《科學日誌》中。

A: Taiwanese-language pop singer Jody Chiang is finally staging a comeback after having “turned off the microphone” for nine years. B: Yeah, she’s set to perform for the National Day celebration at the Taipei Dome this Saturday. A: As the best Taiwanese-language singer, it would be a big loss if she continued her hiatus. B: Recently, Chiang revealed that she quit singing in 2015 due to cancer. A: That’s shocking. But it’s great to see her healthy and able to turn the mic back on again. A: 台語歌后江蕙「封麥」9年後,終於即將復開唱了。 B: 對啊她本週六將參加國慶晚會,在大巨蛋開唱。 A: 江蕙可是最棒的台語歌手,如果不唱歌太可惜了。 B: 她最近才透露,其實2015年是因為罹癌才會「封麥」。 A: 真是令人震驚!能再看到她健康地「開麥」太好啦。 (By Eddy Chang,
A: Apart from Taiwanese-language pop diva Jody Chiang’s comeback, South Korean girl group (G)I-dle is also performing in Taiwan this weekend. B: I know. They have concerts at the Taipei Arena on Saturday and Sunday. A: Actually, to meet their fans’ high demand, they’ve added one more show on Friday. B: They’re even adding a show? That shows how popular they are. A: My favorite group member is Taiwan’s Susan Yeh, known by her stage name “Shuhua.” Let’s go cheer her on. A: 本週末除了江蕙復出,南韓熱門女團(G)I-dle也將開唱唷。 B: 我知道,他們本週六、日將在小巨蛋開唱。 A: 應粉絲的要求,他們本週五還會加場。 B: 還加場?不愧是韓流人氣女團。 A: 我最喜歡台灣團員葉舒華!我們快去幫她加油吧。 (By Eddy Chang, Taipei Times/台北時報張聖恩)
Grenada’s Underwater Sculpture Park is a great example of how art can be combined with environmental conservation. __1__ on the ocean floor of the Caribbean Sea, this aquatic gallery was the brainchild of British sculptor and ecologist Jason deCaires Taylor in 2006. The park features sculptures that function as man-made coral reefs, with holes and shelters to attract marine life, thus forming a strikingly beautiful __2__. The sculptures are placed in a way that diverts visitors from nearby natural reefs. This creative approach to ecological preservation demonstrates how art can inspire, educate, and contribute to the sustainability of our environment. The
City life moves fast, and escalators are a lifesaver for busy commuters. __1__ It is widely believed that this practice keeps traffic flowing smoothly and avoids congestion. While on the road, drivers of slower vehicles are required to remain within the outside lane so that those traveling at faster speeds may pass in the inside lane. Similar to traffic lanes that separate vehicles driving at different speeds, this convention on escalators allows for both efficiency and courtesy. __2__ This system reflects an unspoken understanding that facilitates shared use of the space. However, the city of Nagoya, Japan, has
