學生們停課已經一段時間,大家都轉為網上學習,其他在家的時間不妨利用廢物做做手作,為生活帶來趣味,齊齊邊整邊學科學知識!這次教大家自製一架像飛機的模型,只需五個步驟就可起飛!

製作時間:45分鐘

工具及材料:

舊電池4粒、鎅刀、木筷子3枝、橡筋2條、麻繩

Step 1. 用橡筋將2粒舊電池綁在一起,重複做兩次。

Step 2. 將2枝木筷子上下交叠成十字,並以麻繩固定,如圖示。

Step 3. 以橡筋將電池固定於兩邊木筷子末端,每邊各2粒電池。   

Step 4. 移除裝置的多餘部分。

Step 5. 於中間木筷子貼上飛機機身裝飾,並於兩邊電池貼上機翼。

完成!如圖將小飛機放於重物上,小飛機便可以找到平衡準備起飛!

 

STEAM小知識:

物體的中心就是物體重量分佈的中心點。整個裝置的重心在重物上方,是重量分佈的中心點,所以無論我們怎樣轉到小飛機,它也可在重物上屹立不倒。
