歡迎閱讀《週末科學版》！我們每週六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記錄下來，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！
Neuroscientists and psychologists agree that the brain is divided into two hemispheres — left and right. Generally speaking, the left side of the brain handles logical tasks such as math and reasoning. The right side is more
concerned with creative tasks such as music and images.
In most people one side of the brain is dominant. It’s thought that people who are extremely creative are unlikely to excel at logical thinking. Meanwhile, left brain thinkers might excel at math but fail miserably at music.

In today’s experiment you will do some simple tests on your friends to find out which side of their brain is dominant.
What you will need: a ball, a pen, paper, scissors, a coin and a tube.

神經科學家和心理學家都認同大腦分成兩個半球──左半球和右半球。一般而言，左腦掌管邏輯工作，例如數學和推理；右腦則負責創意性任務，例如音樂和影像等。
大部分的人都會有一個半腦比較發達。所以創意十足的人通常邏輯思考比較差；左腦發達的人可能數學很強，但音樂感卻很差。
今天的實驗中，你要對朋友做一些簡單的測試，看看他們是哪個半腦比較發達。
實驗所需：一顆球、一枝筆、紙、剪刀、一枚硬幣和一根管子。

METHODOLOGY
We need to test which side is dominant for your subjects’ hands, feet, eyes and ears. To achieve our aims, we will test each body part individually. Make sure you record your results in a chart.
Hands: Put your pen and paper on the table and ask your friends to write their name. Then offer your hand for them to shake. Record which hand they use.
Feet: Put your ball on the floor in front of the subjects and ask them to kick it. Then put a coin on the floor and ask them to stand on it. Record which foot they use.
Eyes: Hand your subjects the tube and ask them to look through it. Which eye do they use?
Ears: Tell your friends you’re going to whisper a secret to them. Notice which ear they lean with.
方法
我們要測試實驗對象的手、腳、眼睛和耳朵分別受到哪半腦掌管。為了找出答案，我們要分別針對各個的部位進行測驗。務必把實驗結果記錄在表格中。
手：把你的紙筆放在桌上，請你的朋友寫下自己的名字。然後伸手跟他們握手。記下他們用的是哪隻手。
腳：把球放在實驗對象面前的地板上，請他們踢球。然後放一枚硬幣在地板上，請他們踩在硬幣上。記下他們用的是哪一隻腳。
眼睛：拿一根管子給你的實驗對象，請他們透過管子看東西。他們用哪隻眼睛看？
耳朵：告訴你的朋友你要跟他�她說一個秘密，注意他們把哪隻耳朵湊過來。
EXTENSION
Record the results in a graph and calculate the percentage of people who share the same traits. From your knowledge of your friends, do they fit the profile of left and right brain thinkers outlined in the introduction?
實驗延伸
將實驗結果製成圖表，然後算出特徵相同者的比例。依照你對你朋友的了解，你覺得他們符合引言所介紹的左、右半腦發達者的特徵嗎？
Last year, China’s push for the network certificate and internet ID system sparked widespread debate. The internet ID assigns users a unique code linked to their personal information without revealing their full identity, while the network certificate serves as a digital credential, enabling users to verify their identity across various platforms. This bold policy requires Chinese citizens to connect their online activities to their real identities. An internet “real-name system” demands that every user provide their actual identity information before accessing online services. The goal is to prevent online crime, cyberbullying, and harmful content. China has implemented a comprehensive real-name verification
A: Early this month, Taiwanese pitcher Teng Kai-wei of the San Francisco Giants was called up from Triple-A. B: It’s just awesome. Teng became the 17th Taiwanese to be called up to the majors last year. This marks his second call-up. A: And this time, his jersey number has changed from 70 to 66. B: Who else is likely to be moved up next? A: According to the Major League Baseball (MLB) Web site, Lin Yu-min, Zhuang Chen Zhong-ao, Lee Hao-yu and Cheng Tsung-che are all rising new stars. A: 美職舊金山巨人隊本月初決定，將小聯盟3A投手鄧愷威升上大聯盟！ B: 太棒了，他去年曾打進大聯盟，是台灣第17位打進大聯盟球員。 A: 上次他大聯盟背號為70號，這次背號則改為66號。 B: 還有哪些台灣選手有機會挑戰大聯盟？ A:
Long before numerals and arithmetic systems developed, humans relied on tally marks to count. These simple, repeated marks — often just straight lines — are one of the earliest and most widespread methods of recording numbers. Archaeological findings suggest that humans began tallying in prehistoric times. During the Late Stone Age in Africa, humans began to carve notches onto bones to create tangible records of quantities. One of the earliest known examples is the Wolf bone, an artifact unearthed in Central Europe in 1937. This bone bears notches believed to be an early form of counting. Even more intriguing
A: In addition to Teng Kai-wei, Taiwanese infielder Cheng Tsung-che was called up temporarily to play for the Pittsburgh Pirates in early April. B: Yeah, Cheng is the 18th player in Taiwan’s baseball history to be moved up to the majors. A: Back in 2002, Chen Chin-feng became the first Taiwanese to play in the Major League Baseball (MLB), followed by Tsao Chin-hui, Wang Chien-ming, Kuo Hung-chih, Hu Chin-lung and Lin Che-hsuan. B: Those pioneers were later joined by Lo Chia-jen, C.C. Lee, Ni Fu-te, Chen Wei-yin, Wang Wei-chung, Hu Chih-wei, Tseng Jen-ho, Lin Tzu-wei, Huang Wei-chieh, Yu Chang,
