(高中化學課程及評估指引,P123) • ………………..批判性地閱讀、分析和匯報化學對理解物料世界所作的貢獻；設計海報或單張，嘗試說服不同人士遵守綠色化學原則； • 撰寫報告，總結參觀化工廠獲取的科學知識和概念；開發多媒體製品，說明聚合物合成的過程。教師可因應情況採納不同的方法來評核學生的能力。

Could Lithium Shortages Impede Future Electric Car Development? Example 1. For Non-practical Stream 鋰的不足會否阻礙電動車的發展？

Shortage of Li TOPIC Input of Ideas BAFS (Demand, Supply, Price) Chemistry Geography (Abundance) Poster Article Web-site Outcome

Example 2. For Non-practical Stream Poem:I Am The Sea* A Transit of Power A collection of (e-)'s From all ends of the Earth A collection of seas On contact they flow with polarized tides On a sea floor of charges With a bottom, no sides Fighting with gravity and strong and weak forces Are electrostatic • From those physics courses • No travellers, no winds • yet the sea is not calm • all commit to the cause • in a metallic bond. • (by Russell w. Burgess)

Example 3. For Non-practical Stream Covalent Bonds • By: Rachel, Joanna and Louise • I make atoms come together (是我，令原子在一起) • They share their love for the better (也令他們分享愛) • I make Carbon and Hydrogen share 4 electrons (我令碳和氫分享四顆電子) • Who am I you say?(你可以稱我為何?) • My name is Bond, Covalent Bond

Covalent Bonds （共價鍵） • I only like elements of soft and humble (我喜歡性情温和謙虛的元素) • Metals are definitely not for me (金屬並屬於我的) • Non-metal to non-metal is how it should be (非金屬和非金屬是何物?) • Club Periodic is where we‘ll be (週期俱樂部你可以找到他們) • To the right of the staircase is for us VIPs (在那靠右邊的階級之上) • Instead of taking we like to share(我們無言地分享) • After all it‘s all around us in the air (在那包圍我們的的空氣中)

Covalent Bonds（共價鍵） • Our attraction is strong, it‘s hard to break(我們的吸引力,強得難以破壞) • It‘s just like taking a fat kid away from his cake(就如把油從蛋糕中取出) • If you‘re having trouble attracting and you’ve hit a wall(如果你在過程中撞了版) • Never fear love is here(不用怕, 愛長存) • Give Mr. Bond a call, (請給我電話) • Dial 6.02 x 10^23 • And you‘ll see that he only charges an electron as the fee(只需你收取你一粒電子作為費用)

Drawing & Model • Leaflet • 馬賽克 • Bookmarks(書籤) • etc......

3. Significant ideological change • Need: Your personal experience and perception (需要: 你個人的經驗和領受) • Start: Perception is the reality of your own science world. (以個人的領受出發) • Creativity (創意)

Ode To A Proton • by Shay Heather Davies (5/19/98) • Oh proton, how your positive charge makes me blush!I watch you from a distance, and my heart just turns to mush...If only I was a neutron, we could frolic for awhile,and then my dear I'm sure, I would wear a permanent smile.But alas, I'm an electron, and I must watch you from afar, • so far from where you are. • It seems to me that my fate is sealed, but how can my love not be revealed?My mass will not be complete until you are mine,so give me this chance, and show me a sign.Some day our gazes will meet, and I'll see your eyes,and we will meet together and neutralize...so until that day, farewell my opposite attract,my love for you will always stay intact.
