**<span style="font-family:標楷體;"><span style="font-size:14.0pt;">問題六：將吸管笛放入水中吹，對聲音有什麼影響？</span></span>**

<span style="color:black;"><span style="font-family:標楷體;"><span style="font-size:14.0pt;">（一）研究方法</span></span></span>

<span style="color:black;"><span style="font-family:標楷體;"><span style="font-size:14.0pt;">1. </span></span></span><span style="color:black;"><span style="font-family:標楷體;"><span style="font-size:14.0pt;">以吸管長度6 </span>公分，夾角60</span>度(</span>控制變因)，選擇一端放入水中。

<span style="color:black;"><span style="font-family:標楷體;"><span style="font-size:14.0pt;">2. </span></span></span><span style="color:black;"><span style="font-family:標楷體;"><span style="font-size:14.0pt;">將吸管的一端放入水中，並觀察其分貝量與頻率有什麼不同。</span></span></span>

<span style="color:black;"><span style="font-family:標楷體;"><span style="font-size:14.0pt;">放入水中能吹出聲音，但是一端放入水中的聲音較大，分貝量較高，有鳥聲，響亮且清晰，有時候有水泡聲。</span></span></span>
