記得在四年級下學期的自然課堂上，郭老師在「水的毛細現象」的單元中，教我們做了毛細現象的實驗：先用兩片載玻片夾住蓋玻片，再用橡皮筋綁好，然後插入紅墨水中。我們觀察發現：水會逐漸上升，到一定的高度才停下來；而且夾的蓋玻片越多，水上升的高度越低。這個實驗引發了我們高度的興趣及好奇：如果用各種紙類來做毛細現象，水會沿著紙一直往上爬嗎？還是會像玻璃的毛細現象一樣，停留在一定的高度呢？於是大夥兒決定開始動手作實驗。

一般貨櫃船的甲板形狀由曲線所組成，而貨櫃的形狀則固定為長方體。今將貨櫃形狀改變成自然界中的規律形狀——「蜂窩」（正六邊形），並且將貨櫃船甲板形狀簡化後，試著找出可載運最多貨櫃的排列方式。

本研究在探討糯米橋灰漿成份與配比，查詢糯米橋相關文獻資料隨後進行田野調查與試驗。田野調查項目包含耆老訪談、結構尺寸量度、灰漿非破壞性試驗錘試驗、取樣等；化學檢驗分析包含灰分含量及鈣含量之測定，根據化學檢驗分析的含量數據進行糯米橋灰漿的配比實驗，試驗出最符合目前糯米橋的性質與強度的灰漿配比。 實驗結果得知糯米橋灰漿灰分含量約佔93%~96%、有機物含量約佔4%~7%、鈣含量約佔灰分含量1%~14%，由此推測糯米橋灰漿之主要成分非為糯米及黑糖，而是黏土及石灰。然而在抗壓及抗彎之強度試驗中發現，糯米橋灰縫強度並不高，抗壓強度約為7.911kgf/cm2、抗彎強度約為1.119kgf/cm2，與本實驗試體測試結果相近。最後建議以糯米3.830%、黑糖1.915%、石灰44.364%、黏土49.891%作為設計最佳配比。

本研究以台灣三大岩類做CO2吸附實驗，以期能了解其吸附效果．其中以火成岩(Igneous Rock)的玄武岩(Basalt)與石英安山岩(Dacite)；變質岩(MetamorpHic Rock)的蛇紋岩(Serpentine)；沉積岩(Sedimentary Rock)的長石砂岩(Arkose)；亦以岩石風化物的鹽鹼化土壤(Salinized soil)作為反應物。由酸鹼度pH值、溫度變化CO2吸收量得知，鹼性土壤封存二氧化碳的效率最高，同時有助於中和鹽鹼化作用，進而改良地質，且CO2吸附能力與實驗粒徑呈負相關，實驗物中化學成份含的 Ca、Mg量越多，CO2反應速率愈佳，CO2吸附效果依序為鹽鹼化土壤＞蛇紋岩＞長石砂岩＞玄武岩＞安山岩。

It became necessary to implement a project for the use of vegetable waste generated in the process of handling plantain cultivation, harvest and postharvest, since in Mexico at harvest large quantities of vegetable waste is produced, since only the fruit is used wasting the Pseudostem with leaves and spine. Based on this information, you can take advantage of banana fiber as raw materials in the manufacture of biodegradable sheets and support options that are feasible and possible to make alternative. This is an inexpensive process, also friendly with the environment, so that thousands of banana plants that bear fruit after they become sterile and are discarded without realizing their Pseudostem.

本實驗以銅板、不鏽鋼板、壓克力板、膠合木片與塑膠瓦楞板，以雷射雕刻機切割不同直徑圓板來實驗，並以高中物理方式簡化克拉德尼圖形理論，並由各種材料的同心圓板振出克拉德尼圖案，找到與理論相近的實驗結果。 實驗中發現許多與高中物理課本中理論的矛盾之處： (1)若要用高三物理的直線駐波公式找到材料波速，需要經過重力的修正項。 (2)壓克力片只能振出同心圓的克拉德尼圖案，木片和塑膠瓦楞板則無法振出同心圓圖案。 (3)不論任何材料，頻率的改變皆會影響波速。 本次科展的過程發現，網路上多為金屬板的克拉德尼圖案，極少壓克力與同心圓板材的實驗數據，實驗後發現，各式板材的速率與圖形的變化與銅板稍有不同，可做為不同材料間的比較依據。

本研究主要利用最簡易的金屬還原法研製奈米銀及奈米氧化鐵粒子。而奈米銀主要在隱形的研究,因直徑 200~400nm奈米粒子對部分紅外線波段有吸收的效果。所以本實驗針對這現象設計用熱電偶的探測設計來探討奈米銀在隱形上的研究。另外奈米氧化鐵將其應用在奈米藥物輸送的領域。主要是將藥物包裹奈米氧化鐵粒子，藉著外在磁場的導控達到患部治療，所以奈米氧化鐵的研製在本實驗是極為重要的。界面活性劑的選擇影響實驗很多，界面活性劑有防止奈米金屬粒子團聚的效果，所以無毒、成本及長效性是主要的考量。奈米銀填充於布料將可製作隱形衣及去毒製品。而奈米氧化鐵在後續的氧化處理及其表面沾黏物(藥物)的生長，將可製作奈米探針及藥物，是個很不錯的應用。

一、剛研究此題時，我們以自製的城堡圖及棋子來模擬，試著找出答案，但隨著衛兵數的增加，答案也隨之增多，所以我們開始以討論的方式來尋找答案，但無論如何討論，似乎總會漏掉幾個答案。因此，我們改變原有的思維，再次重新思索題目，尋求解決的方法。最後，利用「不等式」及「不定方程式」來逐一討論各種情況。二、有 m 個衛兵，要站在 n 邊形的城堡崗哨上，且每邊的衛兵人數要相等，則：（一）從 m≦ n ×s ≦2m 中，找出所有符合條件的 s 值（s N）。（二）再由所找出的每一個 s 值中，求出在其條件下的 p、q 值。（p = n ×s - m，q = m - p；p、q N 或 0）（三）由 p、q、s 的值中，求出 a1 、a 2 、a3 、…、a 2n 的值。（a1 、a 2 、a3 、…、a n2 N 或 0）（四）刪除重複的答案後，即為所求。註：1.站在頂點的衛兵人數和p = a1+a 3 +a 5 +…+a 2n_1 2.站在非頂點的衛兵人數和q = a 2 +a 4 +a 6 +…+a 2n 3.衛兵人數和m = p+q= a1+a 2 +a 3 +…+a 2n 4.每邊衛兵人數s = a1+a 2 +a 3 =a 3 +a 4 +a 5 =…=a 2n_1+a 2n + a1

(一)在數學課裡我們學到「四邊形各邊長度固定，它的形狀和大小會改變。」於是心中產生了一個疑問：「四邊形的形狀和大小的改變，在何種情形下面積會最大呢？」\r (二)又學到「四邊形和三角形面積」這一單元，知道四邊形由兩個三角形構成，於是心裡想：「四邊形的對角線和面積是否也有關係？」。\r (三)我們想從最簡單的三角形來討論面積的大小可能和什麼有關係呢？

在一個只能容納一層顆粒的圓形水平容器內裝入兩種不同的顆粒並均勻混合，鉛直振盪一固定時間，觀察兩種顆粒的分離程度。實驗分成兩組，第一組探討不同的頻率和振幅與分離程度之間的關係；第二組則選擇不同質量比、體積比、密度比和恢復係數比的顆粒來探討其與分離程度之間的關係。由分析顆粒的運動軌跡，發現兩種顆粒的分離與否是與顆粒之間的運動是否同步有關。

生活中物聯網家電產品越來越多，想讓家電融入物聯網技術則需要花掉很多錢去購買新的家電用品，因此本研究希望開發出讓舊家電也能銜接物聯網的作品。調查了市面上的許多物聯網家電後，發現廠商各有各不同的控制介面，未有一種共同的控制介面可以彈性、方便的使用。綜上所述，我們串接各種感測器並透過Google App Script實作出可模組化的智慧插座。由分散式架構感測器來控制對應的家電是否該開啟或者是關閉，並調整該插座所控制電器的狀態，如冷氣的溫度調節。其中控制介面透過串接google API設計出可利用google calendar即可對智慧插座排程的功能，更進一步的我們更呼應Web of Thing (WoT)製作出利用網頁，透過不同載具即可監控各感測器的狀態，讓使用者可以依據狀態彈性控制各種電器。

Moss from a roof top was used to treat ear infections in my grandfather’s village. This remedy sparked my curiosity and so I began researching. I was bewildered to discover that the resistance to antibiotics has been labelled as a “Catastrophic Threat” and has been ranked in the same category as terrorism and climate change. Governments globally are urging scientists to identify and produce new antibiotics and reassess novel approaches1. This project aims to evaluate two objectives through the use of several integrated technologies and modified methods: (a) To determine if the extracts, solutions and raw materials derived from Heart wood portion of Picea glauca, Populus tremuloides, Salix spp, Betula papyrifera, Pinus contorta, Quercus alba, Thuja occidentalis, Climacium dendroides, Dicranum fuscescens and Kieselgur, will inhibit the growth of Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, and Escherichia coli. (b) To scientifically reassess my grandfather’s traditional method of treating ear infections using roof moss. The Heartwood portion of each tree was removed using a hammer and mallet. The Heartwood was then burnt to derive the ash and a miter saw was used to make sawdust. The moss was collected, dried and labelled. A Methanol Extraction was performed on all saw dust samples and moss using a Soxhlet Extractor for 24 hours. The ash solutions were diluted, filtered, and neutralized to pH 7. The solvents were evaporated in a Rotary evaporator and the residual material was stored in round bottom flasks. The Kirby Bauer method was modified and a Well Infusion method was devised for the biological assay. The Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, and Escherichia coli were plated using a 0.5 McFarland Standard. Paper filter discs containing 20uL of each extract solution and raw material were precisely placed onto the inoculated plates and incubated for 24 hours. The preliminary results were initially unfavourable, as data could only be collected and analysed for one species; Thuja occidentalis (White Cedar). However, these results were extremely encouraging when the zones of inhibition were measured and analyzed. Confidence Intervals were calculated at 95% and the T-Tests were calculated at a 0.05 alpha level, which indicated significance when compared to the control. The Chi Square values were greater than the critical value of 7.8 and therefore the thorough statistical analysis indicates that the results were not due to chance alone. Literature has indicated that certain components of trees do indeed have antibacterial properties, however there is very limited research specific to the Heartwood portion. Furthermore, I discovered that the Heartwood portion of the White Cedar tree does have certain antibacterial properties that definitely justify further testing. In addition, a combination of examining my grandfather’s possessions and analyzing present data, I can confidently support my grandfather’s traditional method. In conclusion, the use of the Heartwood portion of the White Cedar to combat bacterial infection warrants further exploration. Remedies Recovered from Roof Top Resources may be the solution to this catastrophic threat.
