1. 簡介 多元選修 - 科學好萌 國立中興大學 物理系 施明智 副教授 指導 興大附中 物理教師：黃詩翔

2. 課程目標： 中興大學物理系施明智教授指導，以「國 際年輕物理學家訓練」 International Young Physicists’ Training (I.Y.P.T.) 為課程目標。 具體提升中學生科學相關知識，以科學方 法技能解釋自然現象。 配合 12 年國教中的「探究與實作」發展出 可用的教材，和教學模式。 只錄取 40 名，分組閱讀原文，設計實驗， 探討原理，分組討論，交叉辯論。

3. Problem No. 1 “Packing” 如何在容器內裝最多 M&M 巧克力？ 1.The fraction of space occupied by granular particles depends on their shape. Pour nonspherical particles such as rice, matches, or M&M’s candies into a box. 2.How do characteristics like coordination number, orientational order, or the random close packing fraction depend on the relevant parameters?

4. Problem No. 2 “Two balloons” 兩個氣球中間連通，作實驗觀察此現象 1.Two rubber balloons are partially inflated with air and connected together by a hose with a valve. 2.It is found that depending on initial balloon volumes, the air can flow indifferent directions. 3.Investigate this phenomenon.

5. Problem No. 3 “Magnus glider” 製作，測量，解釋 ” 瑪格努斯效應 ” 的升力 1.Glue the bottoms of two light cups together to make a glider. 2.Wind an elastic band around the centre and hold the free end that remains. 3.While holding the glider, stretch the free end of the elastic band and then release the glider. 4.Investigate its motion.

6. Problem No. 4 “Hovercraft” 製作氣墊 CD 疾速飛船 1.A simple model hovercraft can be built using a CD and a balloon filled with air attached via a tube. 2.Exiting air can lift the device making it float over a surface with low friction. 3.Investigate how the relevant parameters influence the time of the ‘low-friction’ state.
