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!
Taiwan has lots of earthquakes. Do you know why? This week we're going to look at plate tectonic theory. This experiment can be very messy, so make sure you do it over a bowl or a sink.
What you will need:
A box of eggs

Toothpaste
The chamber part of a syringe
A bowl
A large world map
Tracing paper (optional)
Tissues (optional)
▲ Ask a grown-up to help you hard-boil some eggs. Gently tap the pointed end of one of the eggs when it's still raw so that you break a small part of the shell.
▲ As the eggs boil, observe what happens to the damaged egg.
▲ Let the eggs cool. Put the damaged egg to one side.
▲ Very carefully tap an egg on a hard surface so that you get some cracks in the shell. Be careful, you don't want too many, one or two is fine!
▲ The surface of the egg is now a little like the surface of the earth, with separate plates. Try gently moving the plates around by pressing gently on the egg's surface. Move them so that they slide past each other
and move away from each other. How do the plates interact?
▲ Choose a crack and push on either side so that the plates move toward each other and change shape. What does the result remind you of?
▲ Take the syringe chamber and put in a few squeezes of toothpaste.
▲ Take the damaged egg. It should have some cracks along the surface. Hold the egg so that you can see a nice long crack.
▲ Clear part of the shell away at the point of the egg so that you can see the white inside.
▲ Insert the nozzle into the egg white. Then slowly start pumping the toothpaste into the egg. Observe what happens.(CATHERINE THOMAS, STAFF WRITER)
台灣常常有地震,你知道為什麼嗎?這週我們要來探索「地表板塊構造論」,這個實驗會弄得很髒,所以你最好在一個碗裡或水槽中進行。
所需材料︰
一盒雞蛋
牙膏
針筒的筒身
一個碗
一大張世界地圖
描圖紙(非必要)
紙巾(非必要)
▲ 請大人幫你把幾顆蛋連殼煮到全熟;在蛋還是生的時候,先輕敲其中一顆的尖頭端,讓蛋殼破裂一小塊。
▲ 蛋煮熟後,觀察那顆破損的雞蛋有什麼變化。
▲ 把蛋放涼,取出破損的蛋,放到一旁。
▲ 在堅硬的表面上非常小心地輕敲一顆蛋,讓蛋殼產生裂縫;注意,你不需要敲裂太多,一、兩處就夠了!
▲ 現在,雞蛋的表面有點接近地球表面,有分散的板塊。試著輕輕地在雞蛋表面施加壓力,使板塊和緩地在周圍移動,從彼此間滑過又移開,這些板塊如何相互影響?
▲ 選一個裂縫從其中一側施力,這樣板塊會朝彼此移動,進而改變形狀,結果會讓你想到什麼?
▲ 在針筒中擠入一些牙膏。
▲ 取來受損的雞蛋,那上面應該有一些裂縫,托住這顆蛋以便觀察上面完整的長條裂縫。
▲ 將雞蛋尖頭端部份蛋殼剝掉,你就可以看到裡面的蛋白。
▲ 將針嘴插入蛋白,然後慢慢地將牙膏擠壓入蛋中,觀察後續情況。 (翻譯:袁星塵)
As the priest Antonius Hambroek stood in the dim chamber of Fort Zeelandia, his eldest daughter clung to him, her voice trembling. “Father, don’t go. They’ll kill you, and what will become of Mother and my sisters?” Outside, the sounds of Koxinga’s relentless canon siege boomed through the fortress. The defenders were on the brink of collapse. Starvation gnawed at their resolve, and the air carried the acrid stench of spent gunpowder and rotting flesh. Dutch reinforcements from Batavia had failed to arrive, leaving the garrison isolated and hopeless. Hambroek’s face was calm, though sorrow weighed heavily on his
As we bundle up in thick coats to stay warm during the winter, there is a population that has already adapted to extremely low temperatures. These people live in the remote city of Yakutsk, the coldest city on Earth. Yakutsk is situated in the heart of Siberia, which is the capital of the Sakha Republic in Russia. This historic mining city began to flourish in the 19th century following the discovery of gold deposits. Given its construction on permafrost, the average temperature in the city remains below 0°C for over half the year, with winter temperatures dropping to an astonishing -50°C.
A: Apart from 2NE1, Rain and Maroon 5, Japanese band Yoasobi is set to hold two shows in Taipei this weekend. B: Yoasobi? A: Yoasobi is a J-pop duo formed by Ayase and Ikura in 2019, and it’s loved by young people. Haven’t you heard? B: Oops, I’m feeling a little old. A: It sings the theme songs of “Oshi No Ko” (“My Idol’s Children”) and other TV series, leading it to gain popularity among young people. A: 除了2NE1、Rain、魔力紅,日本熱門樂團Yoasobi本週末也將連唱兩場。 B: Yoasobi樂團? A: 這是由Ayase、Ikura在2019年組成的雙人團體,近年來大受年輕人歡迎!你沒聽過嗎? B: 天啊我覺得自己老了。 A: 他們唱了《我推的孩子》等人氣影視作品主題曲,所以大受年輕人喜愛。 (By Eddy Chang, Taipei Times/台北時報張聖恩)
A: Happy Year of the Snake! Did you do anything special during the Lunar New Year holiday? B: I went to K-pop girl group Apink’s concert. How about you? A: I just stayed at home. But I’m going to girl group 2NE1’s show on Saturday. B: Wow, I really love their megahit “I Am the Best,” better known by its Korean title “Naega jeil jal naga.” A: I’m so glad that 2NE1 reunited last year, eight years after they disbanded in 2016. A: 蛇年快樂!你春節有做什麼特別活動嗎? B: 我去了南韓女團Apink的演唱會,你呢? A: 我都宅在家裡,不過這週六要去韓流天團2NE1的演唱會。 B: 我愛該團神曲《我最紅》,韓文歌名《Naega jeil jal naga》超洗腦。 A: 她們2016年解散8年後,去年終於合體真令人開心。 (By Eddy Chang, Taipei
