Once again we are delighted in having all of you engaged in this Campaign and celebrate the IYC 2011 with us!
「國際化學年2011」- 東華三院鄧肇堅小學參賽作品
Awardees:Chu Shun Hei, Poon Ka Chun, Chow Kam Wa, Tso Hong Ming Wong Wang Ching, Lee Kwan Ho(P.4-5)
School/Organization:TWGHs Tang Shiu Kin Primary School
Description:化學與我們的日常生活有密切的關連，只要我們用心觀察每日發生的事情，細心發掘每一個為什麼，不難發現化學的應用府拾皆是。
Concept:本短片透過四個我們經常遇到的例子，反映出化學的功用，藉此引起協助拍攝的同學和在校內觀看短片的同學對化學的認知及興趣。
心繫化學
Awardees:Yang Chun Pong, Koo Ka Wai, Chan Chi Hon, Chung Lai Him, Mak Chun Wing, Yiu Chun Yin(S6)
School/Organization:CCC Heep Woh College
Description:這段影片中的主角求學時覺得化學是一門很煩，很悶的科目，對著一堆又一堆的理論，恨不得把它們都吞進肚裹。他想不透化學到底跟生活有甚麼關係。但是，隨著年紀的增長，他慢慢從日常生活的各方面了解到化學是每分每秒都影響著自己的。而且，化學亦在人與人之間擔當著傳遞彼此心意的橋樑。
Concept:我曾聽過有人說化學這門科目很冷冰冰，唸的都與他沒甚麼關係。我相信有不少人都有類似的念頭。所以，我希望藉此影片讓大家知道因著化學這門知識所誕生的產物大多都是我們生活上不可或缺的。而且，我亦想表達「化學不只帶給我們方便，亦是聯繫著我們的工具。」就如影片中，主角病的時候，家人會送來藥物，藥物把家人的關心同時傳給主角。可見，化學不只見証著人的親情和友情等重要關係，亦可拉近人與人之間的關係。
化學畫出生活
Awardees:晨夏滋群
School/Organization:Creative and Interactive Media Production, Community College of City University
Description:短片內容主要是講述一個男孩的生活。記述他與周遭的人所遇到的事物，利用氣泡來突顯每一種日常生活用物都是由不同化學物質所造成。最後畫面出現愈來愈多氣泡包圍了整個城市，而帶出這個世界到處都充滿了化學來終結。
Concept:這個作品的創作意念是想帶出現代生活與化學的關係是息息相關。而在製作模式方面，我們選用了動畫來表達化學如何融入日常生活當中，希望以輕鬆及有趣的手法帶出話題，帶給觀眾一個新鮮的角度來看待化學與生活的關係，因而引起對化學的興趣，埋下名叫"化學"的種子。
再造紙的奧秘
Awardees:Cheung Kwok Ming, Lo Yan Lam(P.5)
School/Organization:CCC Heep Woh Primary School PM
Description:紙張是由木材內的植物纖維所造的。當紙張濕水，紙張內的水分子就會改變紙纖維的結構，擴大纖維與纖維之間的空間，令纖維變軟和變得鬆散；相反，利用陽光的熱力令水分子蒸發，紙纖維能夠再次重新組織互相緊扣，一張堅韌的再造紙就完成啦。
Concept:我們每天製造的廢紙及剩餘通告數量驚人，正好讓我們反思如何實踐環保生活。我們的主題是「再造紙的奧秘」，希望在推廣回收再造紙之餘，能夠讓同學認識一些科學原理。
Instant Hot Ice
Awardees:SSC Science Society (S3)
School/Organization:St. Stephen College (Whole Day)
In this experiment, we demonstrate the making of hot ice. First we heat up about 20 ml of water in a beaker, then slowly add sodium acetate with stirring. The powder has to be added in bit by bit dissolving until a saturated solution is obtained. Then let it cool down in a refrigerator for about 1-2 hours. At room temperature we pour the solution on to a "seed", which is a really small grain of sodium acetate, and the liquid will instantly turn into solid and release heat, this process is also known as crystallization. If the experiment is to be done at home, we have to heat up the solution with a pot, vinegar and baking soda will be used instead of sodium acetate powder, but the procedure remains unchanged.
The reason why the solution will solidify instantly is because sodium acetate (CH3COONa) is an ionic compound, a compound that contains both metal (Na+) and non-metal (CH3COO-) chemical parts. When the ionic compound undergoes the process of dissolving, the positively charged metal ion, known as the cation, and the negatively charged non-metal ion called the anion will be separated in aqueous solution. In this case, the sodium element will be separated from the acetate element. When a "seed" of sodium acetate is added, it will trigger the solution, and the separated ions will bond in an order and a regular arrangement with each other, changing from liquid state into solid state instantly, and releasing heat. Since this process releases heat, it is used in a warm bag. When the trigger is snap, the liquid inside will turn into solid and release heat. It is also reusable since its melting point is only 58C.
螢光照亮生活
Awardees:Wei Liu
School/Organization:Public
Description:首先簡單展示了生活中經常見到的會出現螢光亮光的東西,畫面定格在螢光棒上引出介紹螢光棒原理的實驗.實驗先介紹組成螢光棒的2 部分溶液:A 溶液含有草酸酯(oxalic ester)和螢光染料 (fluorescent dye),B 溶液含有過氧化氫(hydrogen peroxide)和水楊酸鈉(sodium salicylate).溶液A 與溶液B 混合以後,瓶子裡的液體發出了漂亮的紅色螢光.太快了看不清楚嗎?沒關係,通過重複剛才的實驗,短片把具體的原理告訴大家.因為草酸酯與過氧化氫反應後會產生一種含有很高能量的中間體(短片中有畫出化學反應式),這個中間體分解並把能量傳遞給螢光染料分子,讓它們處於激發狀態.螢光染料從激發單重態躍遷回基態,釋放出光子,也就是我們看到的螢光:)
Concept:很多人對化學談虎變色，短片揭示螢光棒的反應原理，既有趣味性又有科學性。
國際化學年2011 的主題是「化學-我們的生活 我們的未來」，所以化學就像螢光一樣，給我們的生活帶來了便利，以後化學會發揮更大的作用，把我們的生活變得更加美好，點亮我們的未來。
為可洗潔精能凊洗油污?
Awardees:Wu Yu Fung (P.1)
School/Organization:Methodist School (PM)
清洗油污的時候只用清水是不能去污的，但加了洗潔就可以,所以我們會做一個實驗來証實。
首先我們將水放進杯中，然後再加上油。這樣水和油就會分成二層，水在下面而油就會浮上上面。跟著我們用匙攪動它們，等一會它們不會像「糖、鹽」融在水中。而且慢慢會分成二層。它們不能融合的原因是水是極性份子，油是非極性份子。水的份子不能穿過油的份子,還有油的密度比水少，所以油會浮在水上面。
怎樣才能水和油融合呢？那就是洗潔精。在水和油上再加上洗潔精，它們就能融合。原因是洗潔精含有一種成分叫硬脂酸鈉， 而該份子結構是分成二個部分。 一端是帶有電荷呈極性的親水部位。它可以破壞水分子的吸引力而令水的表面張力降低， 有效地平均分配液體之中。 硬脂酸鈉的另一端是非極性的碳鏈， 該份子是帶有親油部位， 可以吸引油滴份子而納入親水部位之中。最後產生的結合物經過攪動之後， 由原本一層浮上水面， 明顯地化成細小油滴溶入水之中。在生活中我們常常都會用到洗潔精來清洗油污，就是加入洗潔精後油污溶入水中，水就能帶走油污。
鉛筆與顏色筆
Awardees:Fan Ho Yi, Chu Po Ying(S.6)
School/Organization:CMA Choi Cheung Kok Secondary School (Whole Day)
Description:鉛筆的主要成分是石墨，而在與紙張接觸摩擦時，紙張表面凹凸不平的纖維，這樣微小的石墨粒便會留在紙面上。而橡皮擦主要以橡膠製成，擦掉字跡時，橡皮擦會產生一條一條的天然橡膠或者合成橡膠，就像柔面一樣，把表面石墨粒包在一起，並且也把紙張表面纖維，連同依附在上面的石墨一併帶走。另外，大部分木顏色筆不含石墨，有油脂、蠟、黏土等混合物，而油脂是滑溜的，所以用橡皮擦是擦不掉的。
Concept:在日常生活中，我們經常會接觸到鉛筆和顏色筆，這兩種筆在外表上和性質上都是十分相似的。但在寫字或繪畫時，我們會發現鉛筆是可以輕易地擦去痕跡，但顏色筆卻不可以。其實大家都因為長時間接觸鉛筆和顏色筆，當然知道鉛筆能夠擦掉，而顏色筆是擦不掉的。人們都知道這樣的結果，因此忽略了當中的原因。所以我們便決定拍這片段來解釋當中的原理是與化學識識相關。
「鬼」混菠蘿溝啫喱
Awardees:Vincy Tam
School/Organization:Public
Description:怕鬼的男子愛看恐怖電影，他在鬼節其間用新鮮菠蘿製作果凍時卻發現果凍竟然完全能不凝固，嚇壞了他。魂魄未定之際，有一名女子手持「人頭」出現在門外……
Concept:當我們製作食物時，總想到用新鮮的食材才是上策。原來，有些食材與其他食品會互相產生化學反應，固不可以一同煮食；片中介紹的新鮮菠蘿和果凍便是其中之一。果凍是夏日受歡迎的甜品，我希望可以透過這條短片來分享我從這個比賽中親身體驗到的化學「貼士」，即使只是在製作菠蘿果凍這個簡單的甜品中，也足以印證化學與生活是息息相關。
