動物二分法

自然習作第30頁/參考課本第65頁

同學們的習作第30頁應該都完成了吧！記得有幾個很有趣的二分法，例如Julianne以「寵物」和「不是寵物」作為分類的理由。雖然很有意思，因此，也發現動物的二分法是會出現例外的，而這些例外的動物種類令人好奇，牠們的生態習性更是值得探討。回到寵物的話題，記得我們看過有人養蜈蚣嗎！

The 30th page of our work should be finished! Remember that there are several interesting dichotomy, for example, Julianne uses "pet" and "not a pet" as the reason for classifying. Although very interesting, it is also found that there are exceptions to the dichotomy of animals, and these exceptional animal species are curious, and their ecological habits are even more worthy of discussion. Back to the topic of pets, remember that we have seen someone raise centipedes wow!

複習以下幾個同學們寫過的動物二分法：

A有翅膀→蒼蠅、鴿子、蝴蝶

B沒翅膀→青蛙、魚、蚯蚓、蝸牛、貓、兔子、狗

A有脊椎→鯨魚、蛇、蜥蜴

B無脊椎→昆蟲、軟體甲殼類

A恆溫→哺乳類、鳥類

B變溫→魚類、兩爬類

Review the animal dichotomy written :

A wings → flies, doves, butterflies

B without wings → frog, fish, earthworm, snail, cat, rabbit, dog

A spine → whale, snake, lizard

B Invertebrate → insects, soft crustaceans

A Constant temperature → Mammals, birds

B changes in temperature → fish, crawlers

今天的3個問題請在留言處回應：

1. 點一下「鮪魚」這部影片(5分鐘)，關於的魚類體溫的探討，在1:25的片段會提到鮪魚如何提高身體溫度的方式。看完請說說妳/你的感想？

2. 哺乳類動物會不會有體溫下降的情形，在什麼情況下？如果有人先回答，接下去不必重複了。

3. 用A、B並列的方式，請妳/你再想出一組動物的二分法？想像的也不錯哦！ 

Please respond to the 3 questions today:

1. Click on the video "Tuna" (5 minutes). The discussion about the body temperature of fish. The 1:25 clip will mention how tuna raises body temperature. After reading, please tell me your thoughts?

2. Will mammals experience a drop in body temperature and under what circumstances? If someone answers first, there is no need to repeat it next.

3. Using A and B side by side, would you please come up with a group of animal dichotomy? Even your imagination !
