I asked such a question in the unit test after i taught my students on fluid, density, forces, and pressure.
Answer:
- When astronauts burp in space, I think it will go on forever like a never-ending echo because of the lack of gravity. However, I also think no sound will come out because there is no pressure. In conclusion, I think nothing will happen.
- I predict that if astronauts burp in space, the burp would last a lot longer because there is no gravity as there is nothing pressing down on it.
- If tehy are wearing a space suit, nothing major would happen, as if they burped on earth. If they aren't wearing a space suit, they are long dead from their body particles trying to spread.
- I think that when they burp, a little gas bubble will come out of their mouths.
- I think when the astronauts burp in space, the burp spreads around their whole ship and tries to get out of the ship, just like the rest of the air.
- The force of burp would push them back.

pi r square
I have taught my Gr. 7 Math tutor student about circle a while ago. Now her school finally goes over it. In order to show that she still remembers the formula in front of her mother:
me: What is the circumference of the circle?
L: you times 2 times radius times 3.14.
Me (tries to explain to L's mom): That means "2 pi r".
L's mom (looks puzzled): isn't it "pi r square"?
Me (asks L): What is "pi r square"?
L: Area!
L's mom: LOL! That's why we have Mandy here!
I think L is so glad that she knows sth that her mom doesn't know.
I am so happy that she remembers sth and begins to like Math.

Smart one
My class was conducting a lab activity to measure the volume of several objects.
One of the questions was:
What item had the largest volume? Explain.
The student's answer:
The tissue box has the largest volume because it is large in the inside in order to fit the tissues.
I can't stop laughing and this reason has filled my day!

仲有十個禮拜
三個星期過去了，我終於get into the pace.
好有鐵人賽的感覺，因為工作量是多得驚人。
聽聞同校的student teachers也病哂，我居然仲未有事，我相信這是神的保守。好感恩=)
同埋在上學前神讓我開始食豬肝補氣，真係好勁！
電視劇「豬肝補氣」大了結局，好似無咗寄託，honey話，要寄託係神身上！
我諗我要揾另一套電視劇追下，等自己多點罪惡感，咁咪會倚靠神多Ｄ囉！=D

當「祝福」變成「咒詛」
爸爸跟我說今年唔好祝人「恭喜發財」同埋「財源廣進」。
原因：「財」跟「裁」同音。「恭喜發財」變成「恭喜快裁」；「財源廣進」變成「裁員廣進」。
一直以來都覺得恭喜人發財並非好事，如今人人以為是「祝福」的「發財」居然聯想為「快裁」。「恭喜發財」終於變為「咒詛」了。哈哈！

Miracles
Miracles are signs, pointing towards a message.
Miracles in the NT points to the salvation of Jesus Christ.
Complain about no more miracles occur at this age? not happen on you? hmmmm... is that your problem or God's problem? and... what do you need *miracles* for?
God can turn impossible to possible. That's what I name miracles.
Last Thursday was stressful for me. I have my weekend booked for dine out, dental, tutoring, birthday lunch. A big unit plan (with 22 lessons) + 5 lessons plans have to be done by Monday.
From my experience, I need at least 8 hrs for one unit plan of 13 lessons, 4 hrs/lesson plan.
How can I get this done???
The only thing I can think of is to hold tightly onto God's calling and His promise.
And.. I got them done. I believe that's a miracle.

Merry Christmas!!!
Saw this bumper sticker all the time and I finally remember to google it online. Yeah... I think this slogan is meaningful no matter who come up with it.
Maybe we should do a step further - Keep Christ Every Day.

Why game!?
Read this today and I wanna share:
6. Our kids should play to have fun, not to win.
Garbage. Taking winning and losing out of sports is like taking the rainbow out of skittles. We need to let kids win and lose because they're going to deal with the emotions that come from succeeding and failing all through their lives, and sports are a great place for them to become familiar with them.
Why sports? Because it's only a game, but the lessons we learn in athletics are universal. Kids need to win because they need to learn how to succeed with grace and humility. So 10 years down the road when they get that coveted promotion over an equally qualified coworker, they handle themselves with class. Similarly, they need to learn how to fail with respect and dignity. They need to be able to put disappoint and rejection in proper perspective for the times later in life when they lose something more than just a game.
Besides, if we didn't keep score at our kids' games, what would we have to yell about from the sidelines?

Inclusion of homosexuality in a classroom
I finally know how to incorporate homosexual issue in a math class.
When you create math problem in class, say "Geneen and her girlfriend", instead of "Geneen and her boyfriend".
The inclusionary language is kinda weird but I can now tell people that it is feasible, not necessarily to teach 1 + 1 = 1.

Multi-tasking
I just remember what I learn in our "Favorite" Engaging Mind lesson about Intelligence.
Is the ability of "multi-tasking" considered as intelligence? or it should be the ability to focus?
In reality, we canNOT "multi-task", i.e. perform multiple tasks at one time. We can only do one task at a time.
The term "multi-tasking" should be replaced by "flipping between tasks".
The ability of "flipping between tasks" measures how many tasks can you flip within a certain period of time, or how fast can you flip between tasks.
How many tasks have you flipped today?
I flipped a lot and got nothing done.... as usual.

實習
話咁快兩星期的短期實習尚有一天便完結。感謝神，雖然我有小小無奈，但原來我比一些同學的經歷好得多。
很多人說實習學到的比課堂上的多，甚至有人覺得上堂咩都學唔到。到這一刻，我仲未認同。
上堂的確俾咗一個comfort zone我們，我們有一班同學可以好似屋企人咁互相支持，可以一齊數實習經過的不是=D 課程內容係讓我們更認識自己，準備我們出去打仗的。
課堂的老師灌輸了一個好健康，好正面的教學態度給我們，他們教我們用不同的方法去令學生對學習產生興趣，這一些是我在學校裏尚未看到的。
我好驚訝我要回到膠片的年代，用power point用了六七年，要復古了。我希望我的power point skill唔好退步。
課程教我們好多學習方式，只是大學過程令我們溺斃於抄notes中，但原來係由十一班開始培養出來的。而我教的第一堂也讓學生抄了成堂notes =D
原來IB class係會抄足一個鐘notes㗎！唔怪之得Ｄ人話寫字寫得快係咁練回來。
我又看到Grade 8的老師每隔五分鐘就叫Ｄ學生靜一點。真係好攰。連Ｄ老師上完堂也散哂。
curriculum有咁多嘢，可以用咩方法去令學生學得到呢？學生要在這個制度下生存和取高分，就要按遊戲規則嗎？
點知今日我又看到極奇寬鬆的教學方法。我又可唔可以融合到化學內呢？
下星期又要回到校園，有一大堆功課等緊我，仲有一個月！就有假放啦！努力努力！

Sick
I am finally *sick* after half a year.. it's the longest time ever that i stayed healthy!!
if i have gone to gym.. i think i can stay another week of healthiness.. anyway... gym partner, i won't blame u.. =P I've just made u feel bad already.
I think this week of practicum is too shocking to my body as well.
Today is a Pro-D day and I made a microscope! and I won a beaker mug in a draw! Yes. a beaker mug after the entire grad school... i could have got one easily at the buck a beaker!
It's interesting to see how contradicting the dream of no rote memory yet lead to assessment of learning and still cope with your school system.
Strong thinker ≠ Strong expressor.
I strongly agree. coz I am one of those people.
Let's see how i can incorporate all these "dreams" together.
Anyway.. My throat hurts and I need to prepare to teach for next week. Pray that I am fine please....

食物相
自從有數碼相機開始，見到咩都影一餐。
特別是食物。
好像飲食專欄作家，當張相一見blog，即刻多了不少顧客。
由唔知幾時開始，食物鋪亦不再介意客人拍照。
相片中的近鏡，往往影得食物很吸引，但與實物相比可能相差很遠。
當我發現越來越多此類相片在facebook和blog出現後，突然覺得：
好幸運，因為見到Ｄ食物居然唔需要掛住食，仲有時間去影相先。
好奢侈，因為有好多選擇，擺得唔靚都未必會食佢。
好奇怪，因為當你擺好多呢Ｄ相上網，就會有人問你係咪好鐘意食野，原來「食野」係可以成為一種嗜好，就好似打波睇戲咁，而忘記咗食野係用來維持生命。
好恐怖，因為我和未婚夫都係Ｄ咁變態的人，不單影食物，連杯杯碟碟，鋪頭裝修都影埋，未婚夫仲整咗個相簿㖭。
好變態，因為基本上每個人的facebook photo album入面，都有Ｄ咁嘅相，甚至tag埋scallop, lobster, 同prawn.
我們正活在一個飲飲食食的世界吧！

First day of Short Practicum
I talked to all my three sponsor teachers.
Three different teaching styles.
Three different personalities.
I got home at 3:30 pm.
5 min drive to work and 5 min drive to home.
I haven't been this early since September!
I feel... weird.
To fill up my day, I went to have my eye examination.
So, I can now join my cell group to hunt for contact lenses and eye glasses!!!

learning to communicate
This month, I've learned how to present.
i.e. to learn how to ask questions
i.e. what kinds of questions to ask in addition to the 5W and H.
how does a "silence" work
how to tell if the student is lying
what my presentation style is,
various techniques in presentation
trying to speak in different tones...
I love this class.
Next stage, I need to learn how to listen.
