Anthocyanin is a water soluble pigment that may appear in various colors such as red, blue, and purple according to the pH. Ube is a fruit in the Philippines that is 3rd of the most cultivated crops. Since Ube contains a lot of anthocyanin, it helps to make the anthocyanin solution. As Anthocyanin reacts to the oxygen quickly it is also used as air pollution indicator because it changes its color according to what substances they are attached to it. To check if the solution reacts to the pollution such as SO2 and NO. When those pollutions are made artificially, examining the intensity of the anthocyanin solution depending on different Mol of the pollutions was able. The power of penetration of lights though the UV-VIS spectrophotometer increases according to the number of molecules of SO2, and also NO. To examine the change of intensity of anthocyanin solution in actual atmosphere, the solutions were exposed outside for several hours. The power of penetration decreases when exposed to an actual atmosphere. The other substances and oxidation were the causes of the changed in color of the solution To facilitate the usage of anthocyanin solution efficiently, it should be preserved, so that the density of specific color will be preserved when used as real air pollution indicator. In order to check what kinds of chemicals can preserve the anthocyanin solution; different kinds of strong acids, strong base, salts, and metals were added to the solution. After getting the data, the characteristics of the chemical which preserved the anthocyanin were scrutinized, than compared to the density of pure anthocyanin solution. To use anthocyanin as air pollution indication as a solid, the Korean traditional paper and cloth were dyed using ube which contains lots of anthocyanin than checked the pixel of red, green, and blue color. Firstly, chose 6 different salts. And then filter and boiled the anthocyanin solution. And then put each different salt in each paper. After that, dried the paper and check the difference of pixel of each paper. As a result, Calcium hydroxide (CaOH2) has highest pixel point. So, using calcium hydroxide to dye clothes is useful and it’s also useful for the air pollution indicator through the experiment. Especially it reacts to Nox and Sox, according to this experiment, it can use for eco-friendly air pollution indicator.

我們時常在放學途中，看到有人撿拾廢置的塑膠袋，但未明究竟。請叫老師後，知道是因為塑膠製品不受細菌分解，無法腐爛，所以收集回爐重新製造，或者乾脆燒了。

我們因被伸卡球吸引著，而開始這次的研究，它的偏向原理，可由翰林版自然與生活科\r 技第五冊9-1 節的白努利原理解釋，首先我們從影片中分析王建民的投球動作、風格及各種\r 球路的特性，我們也量出球體的偏向距離，並估算出偏向力的大小，接著進行了下列三個研\r 究。一是球體旋轉方向和飛行偏向的關係，我們將球體和小馬達結合，並固定在彈簧上，讓\r 旋轉球體在有風流動的風洞中，即可看出球體的偏向。二是簡易發球器的製作，我們利用波\r 蜜果菜汁鐵罐、強力馬達及轉盤，讓快速旋轉的轉盤摩擦保麗龍球體的邊緣，球體可以快速\r 飛行並旋轉著，改變旋轉方向的角度，即可模擬各種球路。三是偏向力的測量，我們利用風\r 洞、電子秤、棒球和強力馬達結合及鐵架，可以找到偏向力的大小和風速及球體旋轉速度有\r 關，最後用得到的數據進行伸卡球進壘位置的分析。

本組研究的主題有二：（一）倉鼠的記憶（二）音樂對倉鼠生活行為的影響。我們利用兩種性質不同的音樂（弦樂與重金屬樂），在飼養倉鼠的環境中連續24 小時播放，觀察音樂對倉鼠生活行為的影響。實驗過後發現，節拍較快的重金屬音樂會帶給倉鼠不安全感；而柔和的弦樂則會使倉鼠行為懶散、不焦慮。另外，利用倉鼠走迷宮所花的時間長短，來尋找出倉鼠短期與長期記憶的時間。在此實驗中發現，倉鼠的短期記憶約7?8 個小時，而長期記憶約11?13 天。

本次研究主要是要做出一支無毒且不會散發異味的白板筆。發現白板筆其中毒性主要來自於溶劑及顏料，聽說客家的藍染是一種天然染劑，因此想利用它做為白板筆的顏料。實驗結果，我們發現濃縮20倍的藍染書寫效果最好。比較出效果最好的自製白板筆墨水後，我們希望它在書寫時也能散發淡淡清香，因此試著加入檸檬皮和橘子皮萃取出來的汁液，看是否會影響書寫效果，實驗結果是加入檸檬皮的汁液比較成功。最後我們將自製的白板筆墨水裝在彩色筆裡，發現寫出來的效果良好，只是寫到最後會變淡；而自製的白板筆也比一般的白板筆好去除痕跡，耐用性也很好。一支無毒且不會有異味的白板筆，在多次的實驗中，終於誕生了。

今天到阿公的雜貨店玩，看見阿公拿了一支筆，在客人付的 1000元鈔票上畫一筆後，「哇！是真的孫中山一千元。」阿公笑咪咪的把錢放進收銀機。我好奇的把那支筆拿來看，阿公才告訴我，那是一支可以分辦真鈔、假鈔，而且價錢不便宜的偽鈔筆。我拿著偽鈔筆在鈔票上一畫，鈔票沒有特別的改變；當我畫在紙上時，我畫過的地方卻變成黑色。為什麼會這樣呢？偽鈔筆真的那麼神奇嗎？這個問題引起了我的興趣，我決定利用課餘的時間，徹底研究偽鈔筆，而且我還要為阿公製造一支便宜的偽鈔筆。

轉槳在水中旋轉會產生水漩渦，轉槳的形態不同產生的漩渦形態也不同，本實驗透過\r 自己設計的各種形態地轉槳來探究所產生的漩渦形態、下拉力量、旋轉力及水流形態。

Paralysis is a debilitating disorder that does not currently have safe and effective treatments. Implantable brain electrodes can be used to read brain waves and convert them into a corresponding motor function to restore movement in paralyzed patients. Tissue deformation induced around the implant site is believed to reduce their viability through the foreign body response. Developing electrodes that minimize deformation is challenging because the mechanical aspects of deformation are not fully understood and non-animal tissue models for testing electrodes are unavailable. Development of pre-clinical models for in vitro testing of the mechanical properties of electrodes can lead to a better understanding of this prevalent problem. The objective of this study was to construct a novel contrast-enhanced, brain mimicking hydrogel using photopolymerizable polyethylene glycol (PEG) polymer that contains alginate microspheres with enclosed gadolinium (Gd) contrast agent. 1.5% alginate microspheres were constructed with enclosed Gd-DTPA-BSA contrast agent and successively added into 10% PEG. Then, this mixture was photopolymerized using a 5 mW/cm2UV lamp to result in a successful brain mimicking hydrogel. Rheological testing showed that its elastic modulus was approximately 1.5 kPa, which is similar to that of a normal human brain. The model is valuable because the presence of the contrast agent in the hydrogel resulted in distinct bright spots on the MRI. This can facilitate the visualization of tissue deformation caused by electrode insertion via comparison of pre-insertion and post-insertion images. This brain-mimicking model has the potential to improve understanding of neural deformation from electrode implants in order to assist patients suffering from paralysis.

身邊常見美麗的串珠作品，但卻未見有關串珠的數學研究。我們進行二年時間來探討串珠。結論如下：研究一：相同大小的珠珠，以「點→線→面」的方式操作，若以某顆珠為中心點，周圍角度和是360°的有：四邊形＋四邊形、六邊形＋三角形，這二種串法可以形成平面。研究二：五邊形組合的「二十面十二面體」(稱為五邊形球體)只要增加四邊形或六邊形就可以擴充。而且使用六邊形較節省珠數，這也是串珠中最常見的作法。研究三：增加六邊形擴大球體時，五邊形維持12 面，六邊形以5 的倍數增加。而且串珠作品只要進行名詞轉換，也符合尤拉公式：珠珠數(稜邊數) ＋２ ＝ 三角形連接處(頂點數) ＋ 面數。研究四：沙發或盒子轉角處的串法，以畢氏定理檢驗證實為直角。

多面體的展開圖是將三次元的多面體，沿著稜線切開張展在二次元的平面圖形。展開圖形成「網狀多角形」，此多角形外圍的邊，就是回覆製作立體模型時的「銜接邊 」。

在科展報告上看到落地生根的葉子要離開植物體才能發芽，引起我們懷疑，我們實驗的目的在控制各種環境，希望找出使落地生根植株未離體葉子的葉緣發芽的條件，我們做了有無不定根系、亮暗、泡水或插水、還有是否去頂芽等條件，發現無根系、整株泡水、照光、去頂芽的處理方式可以使落地生根的芽有最高的發芽率和平均長度最長的根，推翻了葉子要離開植物體，產生癒傷激素促進發芽的假說，我們也從以上這些實驗發現植物激素似乎扮演了很重要的角色，並且深入研究。
