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！
Cup phones 傳聲筒
This week we're going to use two cups and some string to make a telephone that you can use to tell secrets to your friends!
What you will need:

Two disposable cups (You can make more than one set of cup phones. Try using cups that are different sizes and made from different materials, such as cardboard, plastic or tin. If you use tin, be careful of sharp edges.)
A long (about 4m to 5m) piece of string
Paperclips
Scissors
Tape
★ Clean out the cups and poke a small hole in the bottom of each one. The hole should be just big enough to poke the string through.
★ Put one end of the string through one of the cups. Tie it to a paperclip so the string won't be able to go back through the hole (the paperclip should be inside the cup). Attach some tape around the hole to close it up.
★ Do the same with the other cup.
★ Take one of the cups and have a friend take the other. Stand apart, with one person holding one of the cups up to his or her ear and the other talking into the other one. Make sure the string is taut. Don't forget to record your findings in your Science Journal.(michael kearney, staff writer)
本週我們要用兩個杯子和一些線來製作可以用來和朋友分享秘密的電話！
所需材料︰
兩個免洗杯（你可以做不止一組的傳聲筒，試著用不同大小或不同材質的杯子，例如紙杯、塑膠杯或罐頭。若使用罐頭，請留意銳利的罐口緣。）
一段長度約四到五公尺的線
迴紋針
剪刀
膠帶
★ 將每個杯子清潔乾淨後在底部戳一個小洞，這個洞只要大到可以把線穿進去即可。
★ 將線的一端穿過一個杯子，然後綁上迴紋針，讓線不致溜出杯洞（迴紋針應在杯內）。在杯洞口封上膠帶。
★ 另一個杯子也如法炮製。
★ 你拿一個杯子，你的朋友拿另一個杯子，兩人站遠一點，一個人將杯子靠近她或他的耳朵，另一個對著杯子說話，線必須要拉緊才行喔。別忘了把自己的發現寫在《科學日誌》中！

Despite advancements in bicycle security, millions of bicycles are stolen every year. A revolutionary bicycle lock, called “SKUNKLOCK,” takes a proactive approach to deterring thieves. __1__, SKUNKLOCK releases a noxious chemical that could cause would-be thieves to vomit and effectively discourages them from continuing their efforts to steal the bicycle. While conventional locks can be defeated by determined thieves using specialized tools, SKUNKLOCK’s dual approach of physical resistance and chemical deterrence is highly effective, making it a formidable __2__ against bike theft. The U-lock is made of high-tensile carbon steel, which can withstand attempts to break it using brute
