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。

After steel and aluminum, US President Donald Trump has set his sights on slapping 25 percent tariffs on semiconductors, cars and pharmaceuticals. Trump has already slapped additional 10 percent tariffs on goods from China and has also threatened tariffs on Canada and Mexico, plus ordered a study into putting into place reciprocal tariffs. Here’s a look who would be hit the hardest if US import tariffs on semiconductors, cars and pharmaceuticals go into force. SEMICONDUCTORS: ASIA IN THE CROSSHAIRS Semiconductors, or microchips, are the brains in our electronic devices and demand has soared with the development of AI, which

From its stunning temples and glove puppetry to historical architecture and picturesque landscapes, Yunlin rewards those who venture off the beaten path. Yunlin is renowned for its flourishing temple culture. Temples in this region are not merely places of worship but also communal centers where people gather for festivals, rituals, and social functions. One of the most notable temples here is the Beigang Chaotian Temple, which was built more than 300 years ago and is dedicated to Matsu, the sea
Noise pollution is a frequently underestimated environmental hazard. While hearing loss is the best-known outcome associated with noise, emerging research is uncovering how noise affects our health in other ways. From impaired memory and sleep disturbances to cardiovascular problems, the impact of noise is profound. For a start, unpleasant or excessively loud sounds can lead to stress and divert attention. Even everyday noises, such as those caused by traffic, lawnmowers, and construction work, can interfere with cognitive functions and elevate stress levels. “Our ears capture sound, but we hear with our brains,” explains Wei Sun, an audiology researcher at
Nestled within the heart of Taipei, National Taiwan University (NTU) contains a grand and spacious sanctuary where nature and academia come together in perfect accord. Across its expansive 111-hectare campus, NTU reveals a landscape rich with history, lush greenery, and a thoughtfully preserved ecosystem. This tranquil haven invites visitors to take their time wandering among the elegant buildings, to admire the rare plants, and to experience a space that exudes quiet inspiration. Zhoushan Road: A Gentle Prelude to NTU’s Tranquility Beginning at Gongguan MRT Station, the enchanting avenue Zhoushan Road leads visitors into NTU shaded by golden rain trees, cottonwoods, and Javanese
