歡迎閱讀《週末科學版》!我們每週五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!
Today we’re going to build a viewer that focuses light in a similar manner to the human eye or a camera. When you use the viewer to look at the image of a candle, you’ll be able to see that the candle has been flipped upside down!
What you will need:
GRAPHIC: TAIPEI TIMES
An empty Pringles can
A marker
A knife that is able to cut the can
PHOTO: MICHAEL KEARNEY, TAIPEI TIMES
A thumbtack or something else that can poke a hole in the bottom of the can
Wax paper or a tissue
Tape
Aluminum foil or paper
A candle and a lighter
A dark room
► Draw a line around the Pringles can about 5cm from the bottom.
► Cut along the line.
► Use the thumbtack to put a small hole into the center of the bottom of the can. Have an adult help you with this part.
► Attach the plastic top of the can to the bottom portion of the can. If the top is clear, you’re going to need to attach a piece of wax paper or tissue to it.
► Tape the top of the can back onto the bottom portion.
► Cover the side of the can in aluminum foil or paper so that no light can get through.
► Have an adult help you light the candle. Turn off the lights in the room, and look at the candle through the top of the can. You should see an upside-down image of the candle. You might need to get the bottom of the can close to the candle to see it. Don’t forget to record what happens in your Science Journal.(michael kearney, staff writer)
今天我們要來製作一個和人類肉眼或是照相機聚光成像原理類似的觀景器,當你用這個觀景器來觀看蠟燭的影像時,你會看到一個上下顛倒的蠟燭!
所需材料︰
一個品客洋芋片空罐
一個做記號的筆
一把可以割開罐子的刀
一根圖釘或是其他可以把罐子底部戳洞的東西
蠟紙或是一張衛生紙
膠帶
鋁箔紙或是白紙
一支蠟燭或是一個打火機
一間暗房
►沿著品客罐底部往上算約五公分處劃一圈線。
►沿著畫的線裁剪。
►用圖釘在罐子底部中央戳一個小洞;請大人幫你做這個步驟。
►把罐子的塑膠�?b下半截罐口上;如果�?O透明的,你得加上一張蠟紙或是衛生紙。
►用膠帶把罐子的上半截和下半截重新固定回原樣。
►用鋁箔紙包裹住罐身,使光線無法透進罐子裡。
►請大人幫你點燃蠟燭,把房間的燈關掉,然後透過罐口觀察蠟燭,你會看到一個上下顛倒的蠟燭影像;你可能需要拉近罐底和蠟燭間的距離來看清楚蠟燭。別忘了將實驗結果記錄在《科學日誌》喔。 (翻譯︰袁星塵)
Jumping rope has long been considered an excellent form of exercise. It not only burns calories but also improves cardiovascular health and __1__ core muscles. Anyone who has used a traditional jump rope, though, knows that it requires a certain level of skill and coordination. However, with the development of the cordless jump rope, this is __2__ the case. The cordless jump rope is an innovation in the fitness industry that has gained popularity in recent years. As its name suggests, it doesn’t have a cord connecting the two handles. Instead, each handle features a short cord with a
A: Wow, three Taiwanese restaurants just won the 2024 “Asia’s 50 Best Restaurants” awards. B: Awesome! Which three restaurants? A: Taipei’s Logy at No. 22 and MUME at No. 34, and Taichung’s JL Studio at No. 33. B: Actually, there are many more great establishments in Taipei. How about other Asian cities? A: Singapore claimed nine spots this year, making it Asia’s new “food capital.” A: 2024「亞洲50最佳餐廳」名單揭曉了,台灣有3家餐廳上榜。 B: 好厲害,哪3家? A: 台北的Logy和MUME分獲第22和34名,台中的JL Studio獲第33名! B: 其實台北還有很多好餐廳,那其他的亞洲城市呢? A: 新加坡今年入選9家,可說是亞洲美食之都。 (By Eddy Chang, Taipei Times/台北時報張聖恩)
Let’s explore another delicacy primarily known to Tainan locals: floating milkfish in thick soup. Despite its peculiar name, this dish is another Tainan specialty that showcases the popularity of milkfish, which is made into fish paste and served in thick soup. Unlike the version with tutuo fish, which also adds other ingredients to its thick soup, the floating milkfish version primarily features the “floating fish” itself in its thick soup, ensuring that the fish paste remains the star of the dish. 讓我們來探索另一道台南人熟悉的美食:浮水魚羹。這道菜名奇特的美食,再再展現了台南虱目魚料理的多樣。浮水魚羹是用虱目魚漿做成的羹品,雖然和𩵚魠魚羹一樣是羹湯,但不像𩵚魠魚羹會在湯中加入其他食材,而是讓虱目魚漿成為這道料理的主角。 peculiar (adj.) 獨特的;古怪的 The belly of a milkfish is considered the most
The practice of freezing embryos as part of in vitro fertilization (IVF) was thrown into chaos in Alabama this year, when the state supreme court ruled that such embryos should be considered children, exposing clinics to wrongful death claims in the event they are destroyed in the thawing process. In 2021, more than 80 percent of US IVF procedures involved the transfer of frozen embryos, according to a recent report by the US Department of Health and Human Services. HOW IS EMBRYO FREEZING USED IN IVF? IVF uses high doses of hormones to stimulate ovaries to produce as many eggs as possible. Once
