The purpose of this research was to challenge misconceptions about what attracts teenaged boys to girls. It has been observed that some teenaged girls hold stereotypes about boys and believe boys are only attracted to superficial qualities like beautiful hair. The aim is to investigate differences between what girls believe boys find attractive about them and what boys actually find attractive about girls. Hypothesis: There is a significant difference between what teenaged boys find attractive in girls and what teenaged girls think boys find attractive. Procedure Background reading was done to discover which characteristics are commonly used to measure attractiveness among teenagers. A survey questionnaire was used for gathering data. To gather information for the construction of the questionnaire, 4 focus groups were interviewed. The groups were asked to determine indicators of attraction and repulsion. Two separate questionnaires were designed (one for boys and one for girls), based on focus group information, with similar questions which could be used to compare results. Questions were related to personality and looks. The research was representative as 399 teenagers participated in the final survey. Results were collated in Excel tables. Percentages were calculated by using a scientific calculator and Excel. A bivariate analysis was created to examine the main question: ranking qualities that attract boys to girls. A comparison was made between boys’ and girls’ opinions from different age categories. Mean averages were calculated for this question. Other questions were analysed using mode averages translated into percentage of each gender. Graphs were designed using the values calculated. Observations/Data/Results 72% of boys prefer a girl with average looks and an awesome personality but only 37% of girls believed that to be true. The average boys from 12-14, 15-17 and 18-20 year old categories agree that confidence, humour, a nice body, politeness and intelligence are the five most attractive qualities in a girl they would consider dating. The order of these five change across the age groups but are constantly the top five, however confidence and humour always trump a “nice body”. The average 12-14 and 15-17 year old girl overrates a nice body and underrates politeness and intelligence but confidence and humour feature in their top five. The average 18-20 year old girl agrees with the boys priorities. When defining what makes a girl beautiful, 68% of boys highlight personality traits and 59% of boys mentioned physical features. When noting what repulses boys about pretty girls, more than 50% of both sexes agree that smelling bad was most off putting. 52% of boys mentioned taking drugs as unattractive yet only 23% of girls recognized this as repulsive. Conclusions The data supports the hypothesis. Confidence and humour are more important to the average boy than a nice body across all age groups. The younger the girl, the less she understands what attracts boys. 63% of teenaged girls believe that looks are more important to boys than personality. This is clearly not true. 72% of boys value a great personality more highly than good looks.

人類是自然的寵兒，理應主動地接近自然，了解自然。宇宙是自然的全部，包含了天和地，內中還不知道有多少學問，等待看人類去發現，了解和運用，天上的星星雖然只是自然的一部份，但是我們又知道多少呢？尤其是我們這些國中學生，白天看不見星星，晚上又被強烈的電燈遮蔽了星星的面目，深夜嗎？我們要睡了，因為怕明天上學會遲到啊！所以我們想做一們白天也可以看星星的機器，來滿足我們和以後的學弟學妹們的求知慾。我們把構想說給老師聽，經老師們的同意後，就著手做了這一台自學機。

為了證明離子感應電流的存在、測其大小及探討離子溶液代替金屬導體之可行性，我以離子分離電容器、螺線管、羅蘭環及萊頓瓶等器材，設計感應電流的量測方法。藉由電壓紀錄器記錄瞬間的感應電壓，再由測得電壓換算成電流。實驗結果顯示硫酸銅濃度 5%時，離子漩渦電流產生 4.4×10-4(μA)的感應電流，離子螺線管產生 1.89×10-4(μA)的感應電流，且離子濃度約 15%時，漩渦離子產生的感應電流最大；當噴水速度達 1032 (㎝/s)時，帶電水霧產生 3.4×10-4(μA)的感應電流，且噴速越快，產生的感應電流也越大。由實驗結果驗證了離子感應電流的存在及離子溶液代替金屬導體的可行性，藉由感應電流之偵測及離子溶液的導電性，更可拓展至直流發電機、金屬偵測門、及科幻片中在空中飛行的車子等無可限量之生活應用。

我們利用廢棄的資源回收材料，製作一部以風力為動力的風帆車，並且設計實驗來探討哪些因素會影響風帆動力車的行進速度，以及風帆車在不同風向時的行進能力。我們得到主要結論如下：若要使風帆車行進速度增快，帆面面積要大、風帆形狀要選用三角形，且帆面要有點曲度；風帆桅桿要在車身中間位置，重心才會穩定；車體配重要輕、輪子要小，輪子表面具平滑材質。風帆車的風向要避免行走在正逆風左右各約35 度角內，最佳風向角是90~120 度及相對位置的240~270 度，把風帆角度調整至風向線與車身龍骨線之間的平分線上前進，可獲得最快車速。

藉由這次的科展機會，我發現想要買到純正的蜂蜜，是可以透過一些科學的方法來辨識的。首先，可以從外觀的色澤、黏稠度、結晶情形、氣泡多寡與大小、有無雜質、沉澱物及標示等來辨認蜂蜜是否為假貨；再者，利用測定蜂蜜的酸鹼值、葡萄糖比例等，也可知道蜂蜜是否純正。經過這次的研究發現：所謂的一分錢一分貨並不是完全正確的，有時是花冤枉錢買到人造蜂蜜，令人懊惱不已：從今以後，可以買到純正的蜂蜜，應該是此次最大的收穫吧！

本研究主要以一個能夠讓酒瓶站起來的酒瓶架，找出它為什麼可以讓不同形狀的酒瓶站起來，以及酒瓶內液體的量不同，也不影響它的穩定性的原因。結果證明酒瓶架穩定性高的原因，是因為它的底面積大。當瓶內的液體量不同時，而酒瓶和酒瓶架的整體重心會調整，但只要落在底面積內，即可平衡站立。並且也在底面積內找到平衡支點，並以支點計算，滿足槓桿定律平衡的條件。本研究並發現到酒瓶架的設計，除了平衡的考量外，也考慮到視覺上的美感。酒瓶架底部和斜角穿孔均為 45。，可造成酒瓶以水平姿態站立。也可使酒瓶和酒瓶架形成的矩形外觀長寬比，接近黃金比例。接著進一步討論，如何以本研究的發現，設計出特殊造型的酒瓶架，及其他符合力與美的產物呢？

我家的早餐是吃稀飯，可是吃久了覺得厭煩。有一天，媽媽煮豆漿給我們喝：她買了黃豆，洗乾淨，浸在水中，第二天早上，黃豆變大了，就利用果汁機把黃豆打碎，再用布過濾，做成豆漿。我們好高與，有豆漿可以喝了，可是真奇怪！當媽媽把豆漿加熱後，豆漿變或白色沈澱，怎麼煮不出豆漿呢？是什麼原因呢？她不知道；到學校就請教老師，老師不相信，就和我們一起再煮豆漿，找出使豆漿沈澱的原因。

有一次爸爸買了乾電池回來，看到隨貨附贈一個神奇測電條，我發現這測電條還真有趣呢！將電池放上，就能以線條來區別電池的好壞，方便之餘，在我內心卻浮起許多問號，測電條為什麼能測電池？什麼樣的電池能使測電條升得高呢？ …… 帶到班上去找同學討論看看，越談越神奇，於是大家便利用課餘時間，徹底研究這神奇測電條。

那天，瀚毅生日提了一桶乖乖軟糖請全班吃，當桶蓋打開時，發現裡面除了軟糖外，還有一包小蠟燭，大夥兒建議點蠟燭慶祝，接著「祝你生口快樂，祝你生 … …」，當瀚毅許完願吹完蠟燭，正要發軟糖時，蠟燭又燃燒起來了，大家都很訝異，瀚毅只好再吹，結果又熄了，但過一下又燃了起來，咦！好奇怪的蠟燭，它為什麼吹不熄？這問題引起了我們的興趣，便利用課餘時間，徹底研究這吹不熄的蠟燭。

上自然電路時，用了許多電池，用完了要怎樣處理？有的人說要送到回收站，有的人卻丟入一般性垃圾桶。於是我們就去請教教師，老師說應該要回收。但是為什麼不丟入一般性垃圾桶呢？如果隨手亂丟，對大地有影響嗎？為了解開這個疑問，和方便提出實驗計劃，我們就做了問卷調查和進行了一連串的實驗。

我們發現 l+ 2+…+n=n(n+l)/2這個公式可用下列這種積木堆積方式證明：我們先將其式子看成如下的積木排列數：如〔 圖(一)〕 這時，我們將另一塊形狀大小完全相同的積木組合，與圖(一)疊合如圖(二)。 ∴很明頭地，疊合成的積木組合為一矩形，積木數 2S=n(n+l) ∴S=n(n+1)/2 即 l+2+…+n＝n(n+l)/2
