I would like to draw everybody's attention to the alluring symentry of this sunflower. I am quite amazed at Mother Nature's creation, look at the pattern formed by the flower bud!Isn't it amazing?

Today marks a new milestone for sunflower farming- we decided to harvest them. Most of the sunflowers harvested are actually in pretty bad shape....most of them have already began to wilt.

Compare this sunflower with the above picture. Can you see some differences?

Spaced-out and well-defined petals.

Petals that are closed together

Hmm.... this is really interesting, 4 flowers on 1 stalk??

A close-up

:) Yours Truly

The heavy downpour and strong winds that accompanied it for the two nights had wrecked havoc in our sunflowers corner. The wreckage plus innumerable red ants stirred up quite a panic amongst our students!

Mr. Ng and myself went to "inspect" the damages and luckily the worst has yet to be. Phew! We went for a closer look and discovered some interesting things about the sunflowers that we grew. There seems to be a few varieties grown!

The characteristics of the flowers are quite varied.....

1)The flowers have different types of petals, some petals are very closed together while some are spaced-out.

2) Some of the flowers grew singly while a few stalks have 4 to 5 flowers growing on it!

3)The shape of the flowers looked different too..hmm...

Well, students from the three schools, do take a closer look and see if you can spot some more differences. I will upload some more photographs for you...

Good news!

The sunflowers seeds from Singapore bloomed first.

Another close up

This one is just beginning to bloom. We cannot wait for the petals to unfold!
Singapore sunflowers
Taiwan sunflowers are also beginning to get ready to flower!

Hi students from all three schools! This is Mrs Ariel again! We are really excited at this new turn of events!

鳥類身體構造

• 鳥類的翅膀具有許多的功能：包括飛行 、潛入、爬昇、支撐、掩護、戰鬥、表達(如求偶)、發聲。
• 鳥類的羽毛的功能：羽毛是鳥類之生命，羽毛質輕而不易沾濕，除飛翔功能外有保溫、護身、隱身(保護色)、婚姻羽(求偶)等作用。
• 鳥類的骨骼構造：鳥類為了適合飛行，整個骨骼系統為中空、質輕而堅實之骨架，骨骼內之空氣與氣囊、肺相通可減輕體重以利飛行。
• 鳥類的呼吸器官：鳥類的攝食多數為昆虫、種子等高能量食物，新陳代謝及血液循環快，心臟跳動迅速，體溫高在40－42℃之間。因此鳥把大量之空氣貯存於體內裝有空氣的氣囊，氣囊左右各有5個與肺及骨骼相通。氣囊主要功用在飛翔時幫助肺行呼吸作用。鳥類不排汗，其體溫在氣囊中發散，因此氣囊有冷卻身體之功能。
• 鳥類的腳：鳥類後肢分為腿( 脛骨 )、腳( 跗蹠 )及趾，以支持體重及行走奔馳之用，趾通常4趾，第5趾大部份退化，惟雉科鳥尚保留第5趾。
• 鳥類的眼睛：眼睛是鳥類的另一項重要的器官，一般動物眼睛網膜底部有一個容易感光之小凹點叫黃斑，但鳥類黃斑卻有二個，一是用單眼觀察側方，另一個用雙眼眺望前方。又鳥眼網膜上有一梳狀體，候鳥能長程飛行，是否靠此梳狀體是個謎？
• 鳥類的耳朵：鳴叫是雌雄及同伴之間重要語言，為正確辨識不同音調，鳥類具有特別發達之耳朵，一般鳥類鳴叫大都高音調，因此鳥耳特別適合聽取高音調。
