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。

Monosodium glutamate (MSG) has been used in cooking for over a century to enhance flavor. It is often found in Chinese dishes and many other cuisines. Despite its common use, many people misunderstand the safety of MSG. The bad __1__ of MSG started in the late 1960s, when a letter to the New England Journal of Medicine described symptoms like a racing heart, weakness, and numbness after the writer ate Northern Chinese food. While no specific cause was __2__, a series of questionable studies in 1968 began to point the finger at MSG. In one such study, neurologist Herbert Schaumburg and
A: The World Expo 2025 is about to open in Osaka. Is Taiwan going to participate in the event too? B: Sure, the Taiwan External Trade Development Council (TAITRA) will launch a Taiwan pavilion named “Tech World.” A: That sounds cool, and it can showcase our national strength in technology. B: The theme is “Connecting the world to create better future lives together.” The pavilion aims to attract over one million visitors. A: I hope humans can really create better future lives through this year’s fair. A: 2025年世博會即將開幕，這次台灣也會參加嗎？ B: 當然啦，外貿協會的台灣館將以「Tech World」名義參展！ A: 聽起來蠻酷的，應該是想強調台灣的科技實力。 B: 策展主題則是：「連結世界，共創未來美好生活」，希望能吸引到100萬人次參訪。 A: 希望藉由這次世博會，人類真的能共創美好生活。 （By Eddy Chang, Taipei Times／台北時報張迪）
Even as he grows older, Microsoft founder Bill Gates still fondly remembers the catalytic computer code he wrote 50 years ago that opened up a new frontier in technology. Although the code that Gates printed out on a teletype machine may look crude compared to what’s powering today’s artificial intelligence platforms, it played a critical role in creating Microsoft in April 1975 — a golden anniversary that the Redmond, Washington, company celebrated on April 4. Gates, 69, set the stage for that jubilee with a blog post reminiscing on how he and his old high school friend — the late Paul Allen
The study had several issues. Small sample sizes made it hard to draw __7__ conclusions. Additionally, taking a __8__ like pure MSG on an empty stomach is likely to make a person ill in any case. Choosing individuals who already had a history of the symptoms could have created a bias because they were likely to __9__ the reactions again. When real scientific research on the effects of MSG was eventually done, many of the myths surrounding it were proven __10__. The U.S. Food and Drug Administration and other global organizations have found MSG safe to eat. Today, MSG
