         <description><![CDATA[<p>任務一：</p><p>1.觀察「綠-黃」雙色LED燈，通電後，你發現你的LED燈亮什麼顏色？跟其他同學一樣嗎？</p><p>想想看，同樣都是「綠-黃」雙色LED燈，為什麼有人亮綠燈，有人亮黃燈？</p><p>因為，LED燈具有單向導電性質。哪個顏色接正極，LED燈就會亮什麼顏色。</p><p>2.如果希望LED燈亮另一個顏色，可以怎麼做？</p><p><br/></p><p>任務二：</p><p>如何讓電風扇變成螺旋槳起飛？</p><p>1.流經小馬達的電流方向不同，扇葉可以變成電風扇，也可以變成會起飛的螺旋槳。</p><p>2.通電後，運轉中的電風扇若瞬間斷電，會停止旋轉；而運轉中的螺旋槳若瞬間斷電，便會起飛。</p><p>3.請先後分別組裝出電風扇以及螺旋槳這兩種裝置，並使其運轉，再利用瞬間斷電的操作，展示其為電風扇或螺旋槳。</p><p><br/></p><p>任務三：</p><p>請用並聯的方式，設計出以下兩種裝置：</p><p>當按下開關，</p><p>&nbsp; &nbsp; (1)亮綠燈，代表此時運轉中的扇葉功能為電風扇。</p><p>&nbsp; &nbsp; (2)亮黃燈，代表此時運轉中的扇葉功能為螺旋槳。</p>]]></description>

         <description><![CDATA[<p>提問:你知道桌上的兩個透鏡哪個是凸透鏡?哪個是凹透鏡嗎?辨識清楚後，請留下凸透鏡繼續操作。</p><p><strong>任務一</strong>:請依照老師展示的裝置，將F光源、凸透鏡和白色塑膠屏放入光學軌道中。</p><p><strong>任務二</strong>:打開F光源開關，固定F光源和白色塑膠屏的位置不動，只移動凸透鏡，並在白色塑膠屏上找到一個最清晰的影像，將影像拍照並上傳。</p><p><strong>任務三</strong>:你可以讓影像變大、變小或剛好和光源大小一模一樣嗎?說說看，把你的觀察的結果跟老師和同學分享。</p>]]></description>
