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。

Have you ever gazed at the night sky and felt as though the Moon loomed larger than usual? Your eyes were not deceiving you. The Moon’s apparent size can __1__ subtly depending on where it is in its orbit. On certain occasions, it reaches its fullest phase while at its closest point to Earth. When these two events __2__, scientists and the public refer to the spectacle as a “supermoon.” The Moon does not orbit our planet in a perfect circle. Instead, it travels along a more oval-shaped __3__, completing one full orbit every 27 days. Consequently, there are times when

AI-generated summaries are shaking up the media world. Tools like Google’s AI Overviews now provide users with direct answers above the search results, resulting in fewer people clicking on news links. For publishers who rely on that traffic to generate advertising revenue, this shift is hitting hard. The fallout is measurable. Many sites have seen a sharp drop in traffic since AI summary features rolled out. An analysis revealed that a news outlet that had once ranked first on Google lost up to 79% of its traffic when its link appeared beneath an AI-generated summary. Statistics also show that
