How Things Work 萬物原理
Everyday questions with surprising answers: how batteries store power, how a message crosses the ocean, why the sky is blue. Read the answer in English, then see it work in 3D.
生活裡的問題，背後都有驚人的答案：電池怎麼存電、訊息怎麼橫越大海、天空為什麼是藍的。先用英文讀懂，再用 3D 看它怎麼運作。
Every lesson starts with an everyday question. A 3D model shows the answer at work, one idea at a time, and an English reading explains it, with Chinese a tap away.
每一課都從一個生活裡的問題開始：先用 3D 模型看答案怎麼運作，一課只講清楚一個道理；再讀一篇英文短文把它說明白，中文翻譯隨點隨看。
The lessons are grouped into five units. Each lesson has words to learn, a short quiz, common myths, easy ways to remember the idea, and an activity to try at home or in class. Facts and numbers are checked, and every lesson lists its sources.
課程分成五個單元。每一課都有生字、小測驗、常見迷思、記憶口訣，以及在家或在教室就能做的活動。事實與數字都經過查證，每課最後列出資料出處。
13 of 20 lessons are ready so far; more are on the way.

Where the power in your pocket, your wall, and on your roof comes from.
口袋裡、插座裡、屋頂上的電，都是從哪裡來的。
How Does a Battery Store Electricity?

風力發電機怎麼發電？Giant wings at sea turn the monsoon into electricity. Turn up the wind on a 3D offshore turbine, look inside at the generator, and see why twice the wind means eight times the power.海上的巨大翅膀，把季風變成電。用 3D 離岸風機把風調大調小、看進機艙裡的發電機，看看為什麼風速加倍、電就變八倍。Start the lesson · 開始上課 →Unit 2 · 單元二
Information and Communication 資訊與通訊
How a message, a phone call, and your location travel through wires, air, and space.
訊息、電話和你的位置，怎麼穿過電線、空氣與太空。
How Does the Internet Work?
網際網路怎麼運作？A message to Boston is cut into numbered packets that find their own way under the ocean. Send a text or a photo in 3D, lose a packet, cut a cable, and watch the internet fix it.傳到波士頓的訊息，會被切成有編號的封包，各自從海底找路過去。用 3D 傳文字或照片、弄丟一個封包、剪斷一條海纜，看網路怎麼自己補救。Start the lesson · 開始上課 →How Does a Phone Call Travel Without Wires?
手機訊號怎麼在空中傳遞？Your phone talks to a tower using invisible radio waves. Walk a hiker over a 3D mountain, watch the signal bars drop behind the ridge, then add a tower and switch to 5G.手機用看不見的無線電波和基地台說話。在 3D 山區帶著登山客走過山脊，看訊號格數在山後掉下來，再加一座基地台、換成 5G 試試看。Start the lesson · 開始上課 →How Does GPS Know Where You Are?
GPS 怎麼知道你在哪裡？Satellites 20,200 kilometers up keep telling the time. Turn a 3D Earth, watch circles from one, two, three, and four satellites meet at Changhua, then put the phone's clock off and see the blue dot go wrong.兩萬公里高的衛星不停報時。轉動 3D 地球，看一、二、三、四顆衛星畫出的圓交在彰化，再讓手機的時鐘差一點點，看藍點跑掉多遠。Start the lesson · 開始上課 →How Does a Computer Remember Things?
電腦怎麼記住東西？Everything a computer remembers is stored as 0s and 1s. Type a word into a 3D memory chip, watch each letter become eight tiny cups of charge, then pull the plug and see which kind of memory forgets.電腦記住的每一樣東西，都存成 0 和 1。在 3D 記憶體晶片裡打一個字，看每個字母變成 8 個裝電荷的小杯子；再拔掉電源，看哪一種記憶體會忘記。Start the lesson · 開始上課 →Unit 3 · 單元三
Light and Sound 光與聲音
Why the sky is blue, where rainbows come from, and how sounds and pictures are captured.
天空為什麼是藍的、彩虹從哪裡來，聲音和影像怎麼被捕捉下來。
Why Is the Sky Blue?
天空為什麼是藍色的？Sunlight looks white, so why is the sky blue and the sunset red? Watch light cross the air in 3D, slide the Sun down to the horizon, and see the sky change color over Changhua.陽光看起來是白的，天空為什麼是藍的、夕陽又為什麼是紅的？在 3D 裡看光穿過大氣，把太陽拉到地平線，看彰化的天空怎麼變色。Start the lesson · 開始上課 →How Does a Rainbow Form?
