    假設:

    當一條電線被環繞在一根鐵蕊上, 並連接到電源上, 一個電磁鐵便形成了. 有哪些因素會影響電磁鐵的強度? 試寫出一個假設.

    _____________________________________________

    結論:

    溝通

    試形容你會如何利用研究中所使用的材料, 儘可能製造出最強的電磁鐵.

    ______________________________________________________________

    提出假設

    為什麼電磁鐵只會吸引一些特定的物質, 而不會吸引其他的物質?

    _____________________________________________________________

    更深一層的探討:

    預測

    你還可以改變些什麼, 以讓你的電磁鐵磁力更強?

    完成實驗, 並把你的觀察紀錄下來.

    _____________________________________________________________

    探索

    提出你對有關電磁鐵和其磁力強弱的問題.

    我的問題是:____________________________

    我要如何證明:__________________________

    我的實驗結果為:______________________________
