Part9?第九部分是实验部分，学做潜望镜。?潜望镜（Periscope，字典上的解释是a?long?tube?with?mirrors?fitted?in?it?used?to?look?over?the?top?of?something,?especially?to?see?out?of?a?submarine）
教师拿出事先准备好的硬纸板边做边说：“Now?I’ve?got?some?cardboard.?I’ll?fold?the?four?sides?and?stick?them?together.”将纸板按要求及比例折叠好，用胶带将其缠好，接着说：“Now?I?need?to?place?to?mirrors?inside,?facing?each?other.”教师在上、下各放一面镜子，镜子面相对。教师对学生说：“You?see,?It’s?done.?It’s?very?easy.?Look!?This?is?a?periscope.?I’m?sure?you?can?do?it?at?home.?Be?careful,?and?ask?for?parents’?help.”潜望镜是指从海面下伸出海面或从低洼坑道伸出地面，用以窥探海面或地面上活动的装置。其构造与普通地上望远镜相同，唯另加两个反射镜使物光经两次反射而折向眼中。潜望镜常用于潜水艇，坑道和坦克内用以观察敌情。 现在教你如何制作一个玩具潜望镜将一个牙膏盒从中剪开，剪成如图状。装入镜子，镜子与盒壁成45度夹角。(镜子后面可做个45度的直角三角形垫着会更稳)将另一个牙膏盒上面剪一个洞。将牙膏盒拼插在一起。
