歡迎閱讀《週日科學版》！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！
Have you ever seen a lava lamp? This week we are going to have our very own funky homemade lava fun! Make sure you wear old clothes and work in the kitchen, as this experiment can get very messy!
What you will need:

a glass jar
salt
vinegar
water
food coloring
vegetable or baby oil
sodium bicarbonate
a bright lamp or a torch
glitter (optional)
★ Fill the jar a quarter full of water.
★ Now add two quarters of vegetable oil. You should still have a quarter of the space left at the top of the jar. Do the oil and the water mix?
★ Add several drops of food coloring. Watch what happens. Where do the drops go? Do they mix with the other fluids?
★ Drop in a tablespoon of bicarbonate of soda. Where does it go and how does it act?
★ Add a tablespoon of vinegar. Where does the vinegar go?
★ Wait for everything to settle.
★ Now add a large pinch of salt. Watch what happens.
★ Wait for the mixture to settle. Now add some more salt.
★ Try shining the lamp or torch behind the lamp.
★ If you like you can add some glitter now. Where does the glitter sit in the mix?

你看過「熔岩燈」嗎？本週我們要來體驗自製時尚熔岩燈的樂趣！務必穿舊衣服在廚房進行這個實驗，因為過程會很髒亂唷！
所需材料︰
一個玻璃瓶
鹽
醋
水
食用色素
沙拉油或嬰兒油
碳酸氫鈉（小蘇打）
一盞亮燈或是一個手電筒
亮粉（非必要）
★ 在玻璃瓶內裝入四分之一滿的水。
★ 接著再加入四分之二的沙拉油，此時你的瓶子應該還剩四分之一的空間；油和水會混在一起嗎？
★ 滴入幾滴食用色素，仔細觀察有什麼變化產生，色素滴入後會跑到哪裡？會和瓶中其他液體混合嗎？
★ 加入一大湯匙小蘇打粉，小蘇打粉會在瓶中哪處？又會起什麼作用？
★ 再加入一大湯匙的醋，醋會流到何處？
★ 靜置，等所有的東西都沉澱下來。
★ 加入一大撮鹽，觀察其變化。
★ 等瓶中混合液體靜止後，再加入一些鹽。
★ 試著用燈或手電筒從後方照射玻璃瓶。
★ 如果你有準備亮粉，現在可以把它們加進去，亮粉會跑到哪裡去呢？（翻譯：袁星塵）
Many consumers are guilty of filling drawers or closets with old laptops, cellphones, fitness trackers and other electronic devices once they are no longer needed. It’s hard to know where to recycle such items, or it seems costly and inconvenient to do so. The world generates millions of tons of electronic waste — also called e-waste — each year. According to the UN’s most recent estimate, people worldwide produced 62 million metric tons of e-waste in 2022, and only about 22 percent of it was properly recycled. The US’ Environmental Protection Agency estimates that less than a quarter of e-waste is
You’re sitting in class when a classmate asks to borrow a pencil. It seems like a small favor, so you agree without hesitation. The following week, the same classmate asks to share your notes. Later, they request help with a group project. You agree each time — after all, you helped out the first time — but before you know it, it has become automatic. This scenario demonstrates the “foot-in-the-door technique,” a psychological concept that shows how agreeing to small, acceptable demands makes it easier to accept larger ones later on. The name for this strategy comes from door-to-door
A: The four-day Tomb Sweeping Day long weekend begins Friday and will run until Monday. Are you going to sweep your ancestors’ tombs? B: I did in advance last weekend, so I can go to Kaohsiung to see the musical “The Phantom of the Opera.” A: Wow, is “Phantom” touring Taiwan again? It debuted in 1986, so this year marks the 40th anniversary of the show. B: And it’s not just touring Kaohsiung starting March 31, but also Taipei starting April 21 and Taichung starting May 26. A: “Phantom” is one of the world’s Four Major Musicals. I’ve seen all of them, except “Les
Dos & Don’ts — 想想看，這句話英語該怎麼說？ 1. 我們很早到達電影院。 ˇ We arrived at the theater very early. χ We arrived the theater very early. 註︰arrive 為不及物動詞，後面如果有受詞要用 at 或 in。例如：They arrived in Taipei yesterday.。一般大地方，如國家、省、大城市等前面用 in，凡小地方城鎮、學校等則用 at。 2. 開車半小時以後，我們到達了海灘。 ˇ After half an hour’s drive, we got to the beach. χ After half an hour’s drive, we got the beach. 註︰come, go, get（來、去、到達）某地時，在表示地點的名詞前面應該用 to，如 go to school, go to Taipei, come to Shanghai 等。如果這些動詞後面所跟的是 here, there, home 等副詞，則不用 to。 3. 明天我會回辦公室。 ˇ I will be back in the office tomorrow. χ I will be back to office tomorrow. 註︰to be back 一語裡的 back 是副詞，不是介詞，所以後面要用 at (the market) 或 in (the office)。 假如假期結束，要回學校上課了則可說： ? Kids will be back
