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。

A: Which team do you think will win the championship in the 2026 World Baseball Classic? B: The previous champion Japan and runner-up the US are exceptionally strong. A: The Taiwan team was captained by Chen Chieh-hsien with a roster of 16 pitchers, 3 catchers and 11 fielders, and was quite strong, too. B: Yeah, players like Hu Chih-wei, Lin Tzu-wei, Yu Chang and Cheng Tsung-che all played in Major League Baseball. And this tournament marked the first call-up of mixed-race talent: MLB’s Stuart Fairchild. A: There are also some Taiwanese stars playing in Japan, including
Candles were made from animal fats in ancient times. As knowledge and materials improved, people began making them with beeswax and vegetable wax, which burned more cleanly and produced less odor. Before __1__ lighting, candles were considered highly valuable. In many religions, they came to symbolize life and wisdom. Even today, candles are frequently used in religious rituals and for cultural celebrations. The __2__ toward industrial candle making began in 1834, when Joseph Morgan patented a machine that could produce molded candles without interruption. His __3__ marked the start of mechanized production, though for many decades, candles were still
Every few years, the World Baseball Classic (WBC) offers sports fans a real World Series. At its finest, as in the shocking upset on Tuesday last week of the US team by Italy, the games generate the kind of electricity fans feel at the FIFA World Cup. That’s exactly how Major League Baseball (MLB), which owns the WBC, wants it. The tournament, first played in 2006, was designed to boost the league’s profile beyond North America and help it become a global game. In most respects, it’s done better than expected. Yet as the WBC grows, the structure, timing and staging of
Jane Goodall, the pioneering scientist whose groundbreaking research changed our understanding of chimpanzees and reshaped the study of animal behavior, has died at the age of 91. The Jane Goodall Institute confirmed that she passed away from natural causes in California in October 2025 while on a speaking tour. Born in England, Goodall gained international fame in the 1960s after traveling to Tanzania to study wild chimpanzees under the guidance of anthropologist Louis Leakey. At the time, she had no formal scientific training, yet she lived among the animals and recorded their behavior in remarkable detail. Her discovery that
