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！
Ripening fruit 水果的成熟
Have you ever noticed that fruit left in a bowl with ripe
bananas spoils quickly? This week we're going to find out why.

What you will need:
Thirteen unripe tomatoes (green)
Four ripe bananas
Three unripe bananas (green)
Ziplock bags
Paper bags
Three bowls
Sticky labels (or paper and sticky tape)
▲ As you make up each bag or bowl, label it so that you can keep track.
▲ Place a tomato and a ripe banana in a ziplock bag. Seal the bag. Make up another bag exactly the same.
▲ Place a tomato and a ripe banana in a paper bag. Seal the bag. Make up another bag exactly the same.
▲ Place a tomato and a ripe banana in a bowl. Make up another bowl exactly the same.
▲ Place a tomato and an unripe banana each in a sealed ziplock bag, a sealed paper bag, and a bowl. Make up another two bags and a bowl exactly the same.
▲ Place an unripe tomato in a ziplock bag, a paper bag and a bowl. These are your control tomatoes. Seal the bags.
▲ Put one of each type of bag or bowl in the fridge.
Leave the others on the counter.
▲ After a few hours check on each bag and bowl and note any changes that have occurred.
▲ Let the fruit sit for two days, checking it every few hours. If you like you can eat each fruit as it becomes ripe, so that you don't waste it. Do you think the fruit tastes different depending on how it was ripened?(catherine Thomas, staff writer)
你曾經注意到若碗中放了成熟的香蕉，其他水果也會很快跟著腐壞嗎？本週我們將探索原因何在。
所需材料︰
十三顆未成熟的蕃茄（綠色）
四根成熟的香蕉
三根未成熟的香蕉（綠色）
密封袋
紙袋
三個大碗
標籤貼紙（或是紙和膠帶）
▲ 當你在準備密封袋和碗時，將它們個別貼上標籤以利記錄。
▲ 將一顆蕃茄和一根成熟的香蕉放入一個密封袋中後密封，再另外準備完全相同的一份。
▲ 將一顆蕃茄和一根成熟的香蕉放入一個紙袋中封好，再準備一份完全相同的。
▲ 將一顆蕃茄和一根成熟的香蕉放入一個碗中，然後再準備一份完全相同的。
▲ 將一顆蕃茄和一根未成熟的香蕉做為一組，各放一份至可封口的密封袋、可封口的紙袋和碗中。接著再另外各別準備一份完全相同的。
▲ 分別密封袋、紙袋和碗中放入一顆未成熟的蕃茄，這三份是你的控制組。將袋子封口。
▲ 將每種分類的碗或袋子各放一份至冰箱中。剩下的則留在流理台上。
▲ 經過數小時後，檢查每一個碗和袋子，並記錄下變化的情形。
▲ 將水果放置兩天，每隔幾個小時就檢查一下。水果熟了的話可以吃掉，這樣比較不會浪費。你覺得用不同方式熟成的水果口感也不同嗎？ （翻譯︰袁星塵）

It graced statues, colored coffins, and decorated artifacts. It is Egyptian blue, the world’s oldest-known synthetic pigment born in ancient Egypt. Despite its name, it is not limited to a single hue. It ranges from deep blue to greenish tones, often glowing with an almost unearthly brilliance. __1__ In response, the ancient Egyptians developed a synthetic alternative. Not only was it visually striking, but it was also more affordable than imported indigo or natural lapis lazuli. Traces of the pigment have been discovered far beyond Egypt, from wall paintings in Pompeii to tiles in Mesopotamia. However, Egyptian blue began to fall

Contrary to popular belief, glass bottles may pose a greater microplastic risk than plastic ones. A recent study found that beverages stored in glass bottles can contain up to 50 times more microplastic particles than those in plastic containers. Researchers traced most of the contamination to the paint on the outside of the metal caps. The particles found in the drinks matched the cap’s coating in both color and composition. Experts suggest the issue may result from microscopic scratches that form as caps rub against each other during transport or storage. Such scratches can damage the painted coating, leading
