報廢電腦的光碟機直接丟掉十分可惜！我們可以把它拆下來，在齒輪部分裝上曲柄，再將原供電的電線接上LED燈泡後，手搖曲柄就可以讓LED燈泡發亮了！

In our experiment, the novel hydrothermal-galvanic couple method is used to produce nanostructured TiO2 thin film. Compared with the traditional hydrothermal method, whose process is conducted under high temperature and high pressure, the hydrothermal-galvanic couple method is a thermally and electrochemically driven process. The titanium atom is gradually oxidized on the surface driven by potential difference, and eventually become nanostructured TiO2. The advantages of the hydrothermal-galvanic couple method are numerous： they are simple, environment-friendly and energy-saving. Experimental parameters include time, concentration and types of solution. The hydrothermal method is used for comparison. By the cross-section and surface pictures of Field-emission scanning electron microscopy (FE-SEM), we can clearly observe that there is obvious change on the titanium surface, along with increased thickness and altered surface structure. The film of hydrothermal-galvanic couple method is thicker than that of hydrothermal method. Thickness increases with time and concentration as well. Both the hydrophile and decomposition of methylene blue examination indicate that the product on the surface contains photocatalyst-like feature.我們利用新穎水熱-化學電池法製備奈米級二氧化鈦薄膜。相較於一般傳統水熱法高溫高壓的製程，水熱-化學電池法結合了熱能與化學電能，讓鈦原子在電位差的驅動下於表面逐步氧化，最終形成奈米級二氧化鈦粒子，具備簡易、環保、省能的優點。實驗參數包括時間、濃度、溶液種類，並以水熱法作為對照組。由FE-SEM 橫截面圖及表面圖可清楚看到鈦的表面有明顯變化，膜厚增加、表面結構改變；以水熱-化學電池法所得的薄膜明顯較水熱法厚，而其厚度隨著濃度及時間的增加也有增加的趨勢，由試片親水性測試與亞甲基藍吸光度測試，皆顯示試片的表面產物具有類似光觸媒的性質。

The purpose of research:Lies the importance of research in rationalizing the consumption of water during the irrigation of gardens, farms and green spaces. Where the world suffers from the problem of water scarcity, especially groundwater was the slogan of World Water Day in 2007 ((water scarcity)), and therefore we find through studies and scientific research that the world is suffering from a marked decrease in the water up to 30% and thus to drought. The one of the reports issued by the United Nations Environment Programme, that more than half the world's population will live during the next thirty years until in 2032, In areas suffering from water shortages, and West Asia, including the Arabian peninsula will be more areas suffering from water shortages, are expected to live about 90% of the population in areas suffering from water shortages in 2032. Steps of scientific research: Theme: the rationalization of water consumption in irrigation How can rationalize water consumption and maintenance? How to benefit from raw materials to the environment be friends of the environment and water? How to maintain in our hemisphere is suffering from the problems of pollution? R: field environment Compile information: Started to develop the idea of working model in detail (scientific deliberate scheme) of the parts used in the rationalization process model and then work on the ground. Forming hypotheses, research and analysis of information: Assume that the flow of water through the faucet immediately for a period of one minute quantity of 2 liters permission when using pregled control the flow of water and a minute amount of water will be 0.2 liter. Suppose that the system used in the rationalization process is linked with the timing of rush hour drops of water every minute and measuring the quantity flowing from the pipeline, we find it 2 / 10 from the amount of water flowing from the tap directly. Procedures used: Been working model ready by using the following tools: Ban small-sized water Basin water model using plastic-coated shell and clay. Wall hours with wire sensitive prove on the basis of hours rolled aluminium conductor of electricity affected debates clock Plastic trees. Electricity wires - the context of an electric effort to 220 volts. The idea of working model: Labour deliver electric power 220 volts. Scorpion am touching on the sensitive installed base pm (aluminium foil) relates to the electric dynamo worked on the flow of water to the delicate moment senses only wait until touching once again to work regularly. Conclusion: Conclude that the rationalization of water consumption by 90% during irrigate parks and green spaces and farms. Perception of the future work: Research can be developed so that rationalization for more than a minute using the control and distance.

一個美好的星期天，陪媽媽上市場買生鮮食品，我以為顏色鮮明的一定鮮美好吃，媽媽卻說：「顏色太白，太鮮明的，恐怕有添加漂白劑或過氧化氫（即 H2O2 ) ，吃了有致癌的危險唷！」我覺得媽媽言之有理，還是選擇自然、健康的食品才是上策。第二天，和同學談起這件事，引起許多同學對食品添加物的恐懼和探討的興趣，我們這群「最佳拍檔」去請教詹老師，於是，就展開這方面的實驗與研究。

在本研究中，我們想要模仿蟑螂特殊的行走方式來製作可以在各種地形以不減速的方式前進的機器車!在日常生活中，常常看到蟑螂在廚房或垃圾桶旁邊，當我們驚嚇到蟑螂時，蟑螂會非常快速的跑走。蟑螂一般的爬行速度約為1 公分/秒，但在快速行走時，至少能夠約30公分/秒，可見蟑螂之靈敏運動體系，可用於機器車的研究及模擬。

智慧型植物培育室可提供作物最佳生長環境，節省人工管理，避免人為疏失，使能源獲得充分運用，提高經濟品質，極具重要性。一般而言，植物之開花、花粉發育及生長期之適合成長溫度皆有不同，以熱帶性植物來說，雖然耐低溫性較弱但也不一定適合高溫，當溫度超過植物所能忍受之溫度時，便會造成一些現象如花苞不完整、凹凸不平畸形花或生長不良等高溫障害，所以不可單由一般觀念來決定植物的最佳生育溫度；所以我們想發展出一套系統，可供我們所種植的植物生長在最適合的溫度中，而不用去煩惱應該要將溫度設定在何種溫度內，且比一般的溫室價格更低廉，如此以利於農民產物的豐收。

我們首先解決自然課中顏色水擴散實驗遇到的沉澱問題，在觀察顏色水於清水中的擴散現象時，由於顏色水的沉澱效應，造成擴散實驗觀察的困難，藉由調配適當量的酒精於顏色水中，可以方便解決相關問題。另外課堂中有關影響顏色水擴散快慢的因素實驗時，對於擴散快慢的比較，同學們很難有一致的看法，我們便設法對此加以釐清，並提出操作的建議。最後把影響顏色水擴散特性的結果，擴大應用在蛋膜的滲透作用上，就溫度與濃度兩因素而言，它們對滲透速度也有明顯的影響。

風力發電的原理是利用風力吹動風車的葉片，將風力轉換為快速的動能，產生的動力可以轉動旋轉式發電機發電。首先，我依據風速與發電電壓的關係數據，製作一個簡易的風速計，作為各項實驗，測量風速的工具。接著研究，在相同的風速下，風車葉片的面積、旋轉半徑對轉速的影響，進而發現，對小發電機而言，風車葉片的面積、旋轉半徑越大，不見得轉得快。 接著再分別加裝齒輪裝置、更換較大的發電機、及合乎流體力學的風扇葉片，進行各項實驗，確實能逐步提升風力發電裝置的發電量。最後，蒐集生活中的回收材料，製作一台環保可攜式風力發電機。連接上二顆 3號鎳氫充電電池，進行充電，就可以將電能儲存起來。

月球是最接近地球的天體，自古以來就有許多美麗的傳說。記得去年參加科展時，便想到月球視半徑每日不同，分析天秤動時是不是應將月面放大成一樣的大小？因此由每日月球視半徑的變化及原有的天文攝影基礎和數學、物理等知識，是不是可以用來測量月地距離？

近年來國內養豬戶所產的大量豬糞尿廢水，含有高濃度的有機物及氨氮，往往未經處理而排放，因而嚴重影響水體。如果進一步將其固定在高分子單體中，應用在廢水處理程序中可具備下列重點。 (一)微生物固液分離容易，可簡化處理程序。 (二)可提高反應器中微生物濃度，增加微生物之滯留時問。 (三)可提高處理負荷。 因此我們嘗試以固定化微生物，置於自製壓克力槽，處理豬糞尿廢水以期有效去除有機物及氨氮。
