Welcome to Sunday Science! Every Sunday during the summer, we’re going to guide you through some cool experiments that you can do at home. It’s a good idea for you to keep a record of what you do in a Science Journal. That way you can record what you learn, compare results and maybe use them to design new experiments! Have a look at the Science Journal box for some ideas to get you started. Remember to always ask a grown-up’s permission before trying out an experiment.
歡迎閱讀《週日科學版》！在暑假期間，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！
Making a volcano 動手作火山
What you will need:
An empty water bottle
Bicarbonate of soda (baking soda)
Vinegar
Dish soap
Food coloring (red)
A tray (to put everything on)
A cup or pouring jug
A spoon
A funnel (if you don’t have one at home, you can make one from cardboard covered with tinfoil or use a pouring jug to add the ingredients)
Some sand or modeling clay (optional)
Glitter (optional)
Old Newspaper
* Place the newspaper over your working surface.
* Put the tray on the newspaper. Put your empty bottle in the middle of the tray and put the funnel in the neck of the bottle.
* Use the spoon to put baking soda in the bottle. Put in enough to cover the bottom of the bottle well. If you are using glitter add this too.
* If you are using sand or modeling clay, shape it around the bottle (to about 3/4 of the way up) to make it look like a volcano or mountain.
* In the cup or jug combine 1/4 cup of vinegar, two big drops of dish soap and a couple of drops of food coloring (be careful food coloring can stain clothes).
* Pour the mixture into the bottle and watch what happens!
Don’t forget to record what happens in your Science Journal.
所需材料︰
一只空水瓶
小蘇打粉
醋
洗碗精
紅色食用色素
一只托盤（大小需足以放置所有東西）
一只杯子（或是有傾倒口的量杯）
一個湯匙
一只漏斗（假如家裡沒有漏斗，你可以用鋁箔包住厚紙板來自己做一個，或是用量杯來添加材料）
沙子或塑形用黏土（非必要）
亮片（非必要）
舊報紙
* 在工作檯面鋪一張舊報紙。
* 把托盤放在報紙上。將一只空瓶子放在托盤中央，並把漏斗架在瓶子上。
* 用湯匙將小蘇打粉加入瓶內，數量要足以覆蓋整個瓶底。假如你有亮片，也可以在這時加進來。
* 假如你有沙子或黏土，將它們包住瓶子四周（約瓶高的四分之三），讓瓶子看起來宛如火山或高山。
* 在杯子或量杯中放入四分之一杯的醋、兩大滴洗碗精，與幾滴紅色色素（小心別讓色素弄髒衣服）。
* 把這些東西倒入瓶內，看看會發生什麼事！
別忘了將實驗結果紀錄在《科學日誌》喔。

When people listen to music today, they typically use streaming services like YouTube or Spotify. However, traditional formats like vinyl records have regained popularity in recent times. Vinyl records are circular discs that store music in grooves on their surfaces and are played on a turntable. As the turntable’s needle runs along these grooves, it picks up vibrations and translates them into sound. The history of vinyl records dates back to the late 1800s, but material and technological challenges delayed mass production until the 1950s. Despite early versions having short playtimes and poor sound quality, vinyl records introduced a new era
A: Brazilian jiu-jitsu, known as “BJJ,” has become more and more popular. Even Hollywood stars like Halle Berry and Tom Hardy are obsessed with it. B: Some Asian stars, such as Taiwanese actor Eddie Peng and South Korean actor Lee Joon-gi, have also practiced this martial art. A: BJJ is not just a martial art, but also a combat sport. B: I’ve always wanted to try it, but I’m worried about getting injured. A: Diana Wang, a US doctor of physical therapy, is holding a BJJ seminar at PMA Brazilian Jiu-jitsu in Taipei Friday night. Let’s go check out how we
Picture a 45-foot-long animal with a 5-foot-long skull and 3-foot-long arms. It may not seem strange until you realize that a human with those proportions would be 6 feet tall with 5-inch arms. Although the Tyrannosaurus rex went extinct 65 million years ago, the mystery of its unusual body __1__ has fascinated scientists for over a century. Barnum Brown, the paleontologist who first discovered T. rex fossils, initially found it hard to believe that the tiny arms belonged to such a __2__ creature. One of his colleagues speculated that the short forelimbs might have been used to hold the
A: Actually, Brazilian jiu-jitsu is particularly good for small people like you. B: Really? How so? A: According to Diana Wang, a US doctor of physical therapy, the BJJ’s purpose is to help smaller, weaker people defend themselves by using various techniques, such as leverage. B: That sounds interesting. What time does Dr Wang’s BJJ seminar begin tonight? A: The event is scheduled for 7:30pm at PMA Brazilian Jiu-jitsu in Taipei. Admission is free, but donations are welcome. A: 其實你的個子比較小，很適合練巴西柔術呢。 B: 真的嗎？為什麼？ A: 據美國理療醫師王幼瑞博士說，巴西柔術的概念是讓弱小的人，也能利用槓桿作用等技巧防身。 B: 真有趣，王醫師的巴柔研討會幾點開始？ A: 今晚7點半在「台北巴柔運動館」，免費入場自由樂捐唷！ （By Eddy Chang, Taipei Times／台北時報張迪）
