課程概覧

唔少同學一嚟到 Metals 呢一課就開始覺得難,因為大家係要開始學識寫一種新語言——"Chemical Equation"

响呢一課,你需要學識好多 Metals 同其他 Reagents 嘅 Chemical Reactions,而大家係要識得用 Chemical Equations 去表達唔同嘅reactions。

第二樣大家覺得難嘅,就會係 Mole Calculations。雖然都只係四則運算,加減乘除,但因為同學係會接觸到一啲日常生活裏面好陌生嘅單位,所以可能會覺得有啲難。但上完呢個課程之後,同學就可以輕輕鬆鬆學識:

  • 點樣從地彀𥚃面,將有用嘅 metals extract 出嚟。包括用 heating the ore alone, carbon reduction 同 electrolysis of molten ore。
  • 用適合嘅方法去extract 有唔同 reactivity 嘅金屬。
  • 點樣從同唔同嘅 reagents:oxygen,water 同 acid 嘅 reactions,去將唔同嘅 metals 根據佢哋嘅 reactivity 排成 metal reactivity series。
  • 寫 metals 同 oxygen,water,steam 同 acid react 嘅 chemical equations。
  • 乜嘢係 displacement reaction。
  • 點樣計一樣 substance 嘅number of moles。
  • 乜嘢係 Avogadro’s constant。
  • 點樣搵一個 compound 嘅 empirical formula 同 molecular formula。
  • 從一個 chemical reaction 其中一個 reacting species 嘅重量,透過 balanced equation 唔同嘅 reacting species 嘅 mole ratio,去計出其他 reacting species 所需,或者所產生嘅重量。
  • 乜嘢係 metal corrosion,而 rusting 就係 corrosion of iron。
  • 生銹 rusting 要啲乜嘢條件。
  • 乜嘢係 rust indicator,同埋當 rusting 發生嘅時候,會有啲乜嘢顏色改變。
  • 有啲乜嘢因素會令到 rusting 加快。
  • 有啲乜嘢方法可以 prevent rusting 。
  • 點解雖然 aluminium 係比 iron reactive,但係佢嘅corrosion resistant 反而係比 iron 高。
  • 點樣透過 anodisation 去增加 aluminium 嘅 corrosion resistance。

【深度學習】系列啱邊種學生報讀?

【Chem-Animax】系列嘅課程可以幫你掌握到每個課題嘅基本概念。但如果你想更深入了解每個課題嘅要點同答題方針,咁就可以報讀【深度學習】系列嘅課程!呢個系列係專為一啲願意付出時間、心機去為未來前途打拼嘅同學而設。

响課程嘅數小時𥚃面,我會同你一齊深度探討每一個 topic 嘅要點、答題技巧,從零開始帶領住你一步一步掌握所有DSE要識嘅概念!

課程附有一份精美筆記,筆記內容除咗用精簡嘅文字表達之外,仲附有大量 infographics 圖畫,可以幫你加強理解同記憶。加上適量嘅例題、習題加以解明,亦能提升你嘅答題技巧。有咗概念加上技巧,同學應付考試,就自然得心應手。

如報名後另外需要實體筆記,可向 Winter Sir 查詢。

關於導師

Winter Sir 自從取得化學哲學碩士MPhil 之後,便加入教育行列。在一所英文中學任教了超過二十年。任化學科科主任亦超過十年。曾任公開考試閲卷員。
但......因為教得太耐,越教越覺得悶,越冇動力!不安於現狀嘅我,決定响五年前,開始拍以動畫形式進行嘅教學片。懶係雄心壯志,誓要將整個DSE 課程拍成動畫放上 YouTube,可以俾學生隨時隨地睇。經過幾年嘅努力,我所設立嘅 YouTube Channel chemchemday 訂閱人數已經超越4300。所拍嘅短片亦超過666 條。
近年接觸咗翻轉教學 flipped learning 之後,更加成為 flipped learning 嘅狂熱份子,燃燒返我對教育嘅熱誠,唔想再做教育界嘅老海鮮!希望可以將翻轉教學呢一種教學模式推廣到其他學校。
