在民國八十八年九月二十一日那一天，一陣天搖地動後，我們原本上課的教室不能用了，老師帶著我們到時新蓋的簡易教室(組合屋)上課．每天只要一到中午的時後，我們的簡易教室就好像烤箱一樣那麼熱，老師說在短時間內學效沒有多餘的錢可以讓我們買冷氣，而且冷氣機也很耗電，會增加電廠用電量的需求。\r 雖然學校和許多熱心的家長買了一些電風扇讓我們使用，不過，我們還是覺得很熱。在簡易教室內上課，老師很辛苦，我們很辛苦，爸爸和媽媽也很"心苦"。如果每一天的太陽都不對著我們笑，那就好了!

The purpose of investigation was to find and test an inexpensive and effective remedy against malaria. After a great deal of research, I learnt that an effective herbal remedy against malaria may be extracted from Neem (Azadirachta indica)leaves. This remedy is not very well known about all around the world, however, the Neem tree is found in many parts around the world and is therefore a very accessible and inexpensive remedy against malaria. The purpose of my project was also to inform people about the harmful effects of malaria on the human body, as well as to advise people on how to protect themselves.

看到大賣場販賣區吊一塊很大的的廣告，其內容是TM的最新產品名叫「TM大力膠帶」，廣告布條裡面在推銷這個膠帶的黏性有多神奇。於是大家想要用科學的方法來證明是否有如廣告上所說的有超強的黏性。 實驗結果發現，膠帶的黏力可以分為最初黏力與最終黏力，不同使用目的的膠帶這兩種黏力會不同，研究發現，大部分的膠帶最終黏力會大於最初黏力。膠帶與不同接觸面貼合時，其最終黏力會因接觸面的性質不同而不同，因此使用膠帶前要先對物體表面的材質有所了解，才能選用最適合的膠帶發揮最大的黏力。 研究也發現，膠帶在70℃的溫度內其黏力變化不大，表示膠帶在台灣這樣炎熱的環境下使用對其黏力不會有太大的影響。本組研究也發現，若是膠帶與物體貼合後，在膠帶上施予正向力，有助於提升黏力。

在操作理化第二冊實驗9─1時，不小心硝酸銀容易濺到了手及課本，經過一段時間後，沾到銷酸銀的手及課本的紙張都出現了黑色的污點，且實驗中產生的氯化銀白色沈澱稍後亦變成灰黑色，老師說是因為銀離子還原成銀原子之故，但在理化第一冊談到的保溫瓶結構中指出保溫瓶膽處鍍銀以防止熱因輻射而流失，老師提到，這層銀是利用所謂的「銀鏡反應」鍍上去的，然而同樣的銀離子還原成銀原子的反應，為何會有不同的顏色產生呢？種種現象引起我們的好奇，於是便著手實驗，探究原因。

我們利用一連串的實驗探討糯米紙的各種性質，包含燃燒、溶解、導電、黏度等變化，更自己實際製作糯米紙，還將糯米紙作成酒精試紙，來檢測酒精濃度。這才發現小小的糯米紙，看似簡單卻隱藏著大奧秘。

芒萁是中低海拔常見優勢種，以往文獻提出的解釋是「適應台灣酸性土壤」，但我們提出另一假說：芒萁的羽狀複葉具有特殊的樹狀碎形生長形態，二分岔疊代循環，使其生長效率提高，具有較佳的生長優勢因而成為地被層優勢種。我們從野外生長形態及模擬生長模式進行驗證。野外調查結果，複葉枝條長度與分岔角度有遞減的趨勢，以降低末端小葉重疊比例而提高光合作用葉面積。軟體模擬結果，最佳生長模式為二分岔3階層且分岔長度比為1.0，分岔角度為100。重複二分岔次數模擬中以3階層效率最好，最差為6階層，此結果與野外生長狀況相符。從野外及模擬資料互相比對後，發現樹狀碎形生長模式能讓能量收支達最佳化，有較佳的生長效率，有助成為優勢種。

最後留下數字會是多少？該問題在台灣的全國中小學科學展覽出現多次。而資訊界演算法大師Donlad E. Knuth 在其著作The Art of Programing，CONCRETE MATHEMATICS （具體數學），針對該數列作詳細的說明；但是，不論是歷屆全國中小學科學展覽或是大師著作，對於該問題，都只是談及殺1 留β或是殺α留1。本研究利用獨創α分類、n 及k 分類、d 函數、b 函數及循環、n 及y 分類、碎形數列和演變關係，將約瑟夫問題探討範圍提升至殺α(個數)留β(個數)，直到剩下最後1 個數時就不能再殺了，遊戲終止，倒數第k 個留下的自然數是多少？同時，本研究在殺α(個數)留β(個數)下，指定自然數y 為酋長，酋長不能被殺，殺到酋長時遊戲停止，求剩下的自然數有幾個？會發生什麼情形？The Josephus problem refers to what will be remaining when arranging n natural numbers in a circle and starting killing one and leaving the next one alive. The problem has been on display for many times in Taiwan National Primary and High School Science Exhibitions (as shown in Table 1). And, the information algorithm master, Donald E. Knuth has elaborated on the array in his works The Art of Programming, CONCRETE MATHEMATICS. However, both the past science exhibitions and the master’s works are limited to discussions on cases of killing 1 leaving β or killing α and leaving 1. This research employs uniquely created α classification, n and k classifications, d function, b function and loop theory to extend the Josephus problem scope to killing α leaving β to find out what the remaining natural number is by No. k counted recursively. Meanwhile, this research designates natural number y as the chieftain, which can never be killed. The game is over when the chieftain is to be killed. The problem is to work out how many natural numbers are remaining. And what happened?

Purpose Although Body Mass Index (BMI) is accepted by the World Health Organisation (WHO) as the standard method of measuring a person’s obesity or lack thereof, it is restriction to the two measurements of height and weight. This makes its accuracy questionable. By using other easily obtainable body measurements, a better way of evaluating Body Mass Index is possible. The purpose of this project was to show that the BMI formula is only accurate to a certain degree and that its validity varies depending on certain factors used in my project. Procedure 50 Adolescent female aged 16-20 and 50 women aged 40-56 none of whom were noticeably obese or underweight volunteered. Using a simple questionnaire, several measurements were taken – age in months, caliper measurement of tricep and hip bone, shoe size, height in metres, hip waist and wrist measurements (cm), exercise per week, heart rate and body type. Results were tabulated and graphs drawn using EXCEL. BAI (Body Adiposity Index) measurements were calculated for all volunteers. Results The girls and women with pear and hourglass figures were classified by BMI as overweight or obese. The girls and women who exercised a lot were also unfairly classified by their BMI readings. Many of the graphs show that BMI is not accurate, however, others show that there is merit to the formula. Conclusions The results while interesting require a larger sample group to be conclusive. It would appear that the BMI formula needs to be extended in order to improve its accuracy. Further research includes: 1. Larger sample group, 2. Representative age groups, 3. Investigate males, 4. Look at data for different ethnic groups, 5. Research into BAI formula as a possible substitute, 6. Develop an improvement on BMI. Although, there is some merit to BMI formula, it could be greatly improved with the use of other measurements including those used in this project.

金屬是屬於帶有自由電子的物體，因此有著金屬光澤、高延展性、易導電導熱等特徵。\r 汞即為水銀，是常溫常壓下唯一的液態金屬。不銹鋼的基本元素是鐵，還有其他金屬例如：鉻、鎳、鈦、鈷等，所以不銹鋼仍然屬於金屬原料。\r 水刀不是刀，它是將水加壓至很大的壓力然後從特製的噴嘴（噴嘴直徑非常小，大約是0.1mm到0.5mm）。水通過噴嘴時便會產生一道每秒將近1000公尺的水箭，此種高速水箭可以用來切割各種非金屬物質。如在水箭中加入高硬度細沙，則可增強其切割能力，可用來切割金屬等硬度較高的物質。

夏天在草地上或柏油地上遊玩時常感覺炎熱程度不同，或晚上在都市與鄉下所覺悶熱程度有極大的差異，想這必和各種之溫度的變化有關，於是我們一些有志同學一起進行測量研究。

蘿蔓A菜莖部內有白色乳狀液成分為橡膠醣、甘露醇、樹脂和萵苣素，若暴露於自然的環境中1-2日，莖部細胞本身可氧化形成紅色似人類的結痂，乳汁並非變紅的主因，莖部特殊的結痂狀集中在用來運送物質的維管束，而阻止了水分和養分的流失；人體受傷時以血小板用於凝血並透過免疫系統來抵抗外敵，而蘿蔓A菜則在莖部產生鹼性環境用以減緩細菌的生長，儘管其只剩莖的一小節，不施水分三週後，仍會長出莖與葉子最後再長出根變成一個完整的新個體。 蘿蔓A菜的結痂其作用與人的血液凝結是否相同，利用抗凝血劑藥物阿斯匹靈的施給，發現可延緩結痂的生成，也可由抗氧化劑維他命C來抑制結痂，可見得植物雖無血小板，但是卻有類似形成結痂的機制防衛來保護並修復傷口。

本研究以攝影紀錄的方式，透過電腦進行影像分析，記錄不同刺激下美洲蜚蠊(Periplaneta americana)的觸角擺動模式，計算出各項觸角運動的參數，以瞭解光線(光刺激或光適應)、震動刺激、喝水與進食對其觸角行為的影響。我們發現在不同因子的刺激下，觸角擺動的模式具有差異，若兩種不同的刺激同時發生，蜚蠊觸角的行為亦具整合性的反應。蜚蠊於不同狀態下(如喝水或進食)，對相同的刺激有不同的反應，證明蜚蠊觸角的行為模式，受環境因子與個體狀態調節。透過掃瞄式電子顯微鏡的觀察，也發現觸角具多種感覺毛，且雌雄的感覺毛的分佈與數量具有差異。綜合以上發現，證明觸角除了為敏感的受器，亦為能反映出生理與環境狀態的動器，同時也適合進行發展檢測器的仿生學應用，用來檢測環境中物理及化學因子。The aim of this study is to investigate the different swing motion modes of antennae of American cockroach (Periplaneta americana) by computer-aided Imaging Analysis. The parameters of each swing movement were calculated in order to analyze how light (including light stimulation or light adaptation), vibration, food and drinking water may affect the antennae behavior of American cockroach. It was found that the antennae swing motion modes were significantly different under different types of stimulus. If two different types of stimulus occurred at the same time, the reactions of antennae motion may become conformable. Under different environmental conditions (such as food or water), same stimulus may result in different reactions. The antennae behavior has shown to be significantly affected by environmental conditions and individual physiological status. Through the observation with scanning electron microscope (SEM), it was found that the antennae has many types of sensilla; and the distribution and quantity of these sensilla are significant different between sexes. In conclusion, not only the antennae are considered as the sensitive receptors, but also they are the important effectors to reflect physiological status and environmental conditions. The current model is suitable for the development of specific detectors in the applications of Bionics to detect the physical and chemical factors in certain environments.
