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！

a glass jar
salt
vinegar
water
food coloring
vegetable or baby oil
sodium bicarbonate
a bright lamp or a torch
glitter (optional)
★ Fill the jar a quarter full of water.

★ Add several drops of food coloring. Watch what happens. Where do the drops go? Do they mix with the other fluids?
★ Drop in a tablespoon of bicarbonate of soda. Where does it go and how does it act?
★ Add a tablespoon of vinegar. Where does the vinegar go?
★ Wait for everything to settle.
★ Now add a large pinch of salt. Watch what happens.
★ Wait for the mixture to settle. Now add some more salt.
★ Try shining the lamp or torch behind the lamp.
★ If you like you can add some glitter now. Where does the glitter sit in the mix?

你看過「熔岩燈」嗎？本週我們要來體驗自製時尚熔岩燈的樂趣！務必穿舊衣服在廚房進行這個實驗，因為過程會很髒亂唷！
所需材料︰
一個玻璃瓶
鹽
醋
水
食用色素
沙拉油或嬰兒油
碳酸氫鈉（小蘇打）
一盞亮燈或是一個手電筒
亮粉（非必要）
★ 在玻璃瓶內裝入四分之一滿的水。
★ 接著再加入四分之二的沙拉油，此時你的瓶子應該還剩四分之一的空間；油和水會混在一起嗎？
★ 滴入幾滴食用色素，仔細觀察有什麼變化產生，色素滴入後會跑到哪裡？會和瓶中其他液體混合嗎？
★ 加入一大湯匙小蘇打粉，小蘇打粉會在瓶中哪處？又會起什麼作用？
★ 再加入一大湯匙的醋，醋會流到何處？
★ 靜置，等所有的東西都沉澱下來。
★ 加入一大撮鹽，觀察其變化。
★ 等瓶中混合液體靜止後，再加入一些鹽。
★ 試著用燈或手電筒從後方照射玻璃瓶。
★ 如果你有準備亮粉，現在可以把它們加進去，亮粉會跑到哪裡去呢？（翻譯：袁星塵）
