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 wondered if plants lose water from their leaves? This week we're going to do an experiment to find out.
What you will need:
Various kinds of leafy plants

Small plastic bags or ziplock bags
Tape (optional)
▲ Before you start, note that this works best on plants exposed to the sun.
▲ Put a plastic bag around one leaf on each plant. Close the bag in such a way that water won't be able to easily escape. Be careful not to crush the stem of the leaf.
▲ Close another bag and leave it to one side. This is your control.
▲ Periodically take a look at the bags. Note how much moisture appears in each of the bags.
▲ After a couple hours, take the bags off the plants and record your observations.

你是否曾想過植物內的水分會不會從它們的葉子流失呢?這個星期,我們將要做實驗來驗證。
所需材料︰
各類多葉植物
小塑膠袋或是封口袋
膠帶(可有可無)
▲實驗以前,請注意:如果將植物暴露在陽光下,實驗效果會最好。
▲將塑膠袋套在每一株植物的其中一片葉子上,然後將袋口封好,讓水氣不容易跑掉。請小心不要把葉柄給壓壞了。
▲將另一個塑膠袋也封好,然後放置一旁,作為對照組。
▲定期觀察這些塑膠袋,注意每一個袋子有多少水氣出現。
▲數小時後,將塑膠袋從植物上拿下來,並記錄所觀察到的現象。

The deep waters off the coast of California are home to a bizarre creature: the flapjack octopus. This creature, known for its pancake-like appearance, spreads itself thin on the seabed as a clever survival strategy, making it difficult for predators to spot and capture it. With its unique, umbrella-shaped body formed by webbed arms, the flapjack octopus moves through the water in a graceful manner. It propels itself forward by rhythmically moving its body and contracting its webbed arms. Its pair of ear-like fins, which move independently yet with remarkable coordination, also help it explore the deep-sea environment. These
Bilingual Story is a fictionalized account. 雙語故事部分內容純屬虛構。 I stand by the Miluo River as dusk falls. The court betrayal is too much. I served Chu with loyalty. I forged alliances and fought corruption. But the whispers of jealous courtiers, the murmurs of treason, spoke louder. The king cast me out. The water looks calm. It promises peace. I step in. The river is cold against my legs. I hear shouts behind me — fishermen calling my name. I keep walking. The calls grow louder, but I do not turn around. The water rises to my chest. It pulls at me. I
In Taiwan, people can use a platform to rent a power washer for a weekend or share unused garage space for someone’s storage needs. These are examples of the sharing economy, a consumption model that has gained widespread adoption worldwide. This approach allows people to rent or share assets like cars, homes or even services, typically through online platforms. This innovative model poses a simple yet powerful question: why purchase infrequently used items when sharing is more practical? By making useful but idle resources accessible, the sharing economy turns them into sustainable opportunities. Internationally, platforms like Airbnb and Uber have popularized
Continued from yesterday(延續自昨日) https://www.taipeitimes.com/News/lang Many people may be familiar with flapjack octopuses thanks to Pearl, a charming character from the Pixar film Finding Nemo. However, her portrayal presents several scientific inaccuracies. In reality, flapjack octopuses are deep-sea creatures, which are unsuitable for the brightly lit shallow reef environment depicted in the film. Their primary defense mechanism relies on their reddish coloration, which would be ineffective in the well-lit shallows. Pearl’s famous line, “You guys made me ink,” is another fictional detail that is not consistent with the observed actions of real flapjack octopuses. As common as it is in many other octopus
