Valentines day~

Well well well, its a season to be jolly, yada yada, love and stuff. For you all lovebirds out there, have fun dating at overpriced roses and gifts! (*cough* suckers*) Frankly I don't know what the hell are these people up to, before that "special" day, prices are cheap as ever, roses are like 80 cents says LFL, then now they're like 5 bucks. I'm thinking to myself: wow, since when was the last time her husband used "overpriced stuff" as an excuse not to get her any? Poor LFL, mebbe her husband didn't get her any (evil grin)"

Well, a little lesson on this special day:

St. Valentine's Day falls on February 14, and is the traditional day on which lovers in certain cultures let each other know about their love, commonly by sending Valentine's cards, which are often anonymous. The history of Valentine's day can be traced back to a Catholic Church feast day, in honor of Saint Valentine. The day's associations with romantic love arrived after the High Middle Ages, during which the concept of romantic love was formulated.

The day is now most closely associated with the mutual exchange of love notes in the form of "valentines." Modern Valentine symbols include the heart-shaped outline and the figure of the winged Cupid. Since the 19th century, the practice of hand writing notes has largely given way to the exchange of mass-produced greeting cards. The Greeting Card Association estimates that, world-wide, approximately one billion valentine cards are sent each year, making the day the second largest card-sending holiday of the year behind Christmas. The association also estimates that women purchase approximately 85 percent of all valentines.

Hmm, to lengthen the blog, maybe i can use my 2 legged cat skill ( san jiao mao gong fu) to try and summarize what we have learnt today =D:

Chinese: Crappy test =_=

English: Another crappy test =_=

Recess: if one is late for chapel, one can use the staircases from the side of the hall to enter WITHOUT getting caught for being late. This has been proven by d.kwek, victor, yilong, and plenty of other guys in our class.

Biology: We learnt PLANTS! (gaseous exchange in em)

In leaves and stems, they don't have lungs like us (haha, loooserss XD), large surface area to volume ratio, uses lame and simple diffusion to meet their needs.

Diffusion occurs through: Stomata and Lenticels (cork tissue in the old woody stem beneath the epidermis)

How does it diffuse?: Oxygen from surrounding diffuse into the intercellular spaces among cells of the leaves and stems.

-Oxygen diffuses in the moisture on the walls of cells then into the cells
-Reaches the cells deeper in not connected to air
-Carbon dioxide produced by respiration diffuses out of cells into intercellular spaces then to the atmosphere via stoma

Miss lam says: SOOO DO YOU THINK ROOTS NEED TO RESPIRE?! OF COURSE! *more body languages* BECAUSE THEY ARE CELLS! THEY NEED ENERGY TO FUNCTION!

In roots:
-as stated above, root cells need their oxygen for respiration and growth
-they get it from soil water where dissolved oxygen exist
-carbon dioxide produced form respiration diffuses out of the roots

the rest was pretty much a revision of what we learnt for transportation in plants w/e, so shan't waste my blogging space =D

E.Maths: Loci, sth that cannot be taught through words, NEXT!!

Physics: Basically she just got 2 crappy looking rods of materials and started showing us "magic" tricks by making tissue jump like a bunch of hungry dogs for a doggy treat. Anyway, by rubbing those materials with a woollen/silk material, she just took out a particular charge making it positively charged for eg, from 0 charge, it becomes +1. As for the tissue, its NEUTRAL: 0, but theres electrons and protons in it, so when she put the positvely charge rod near it, all the electrons in the tissue will be attracted to the rod like a pack of thirsty kids on a milo van, cause unlike charges attract right? So anyway, there will be a resultant force towards to rod so it "jumps". Since I am not some guy really good at physics, I shan't elaborate futhur just in case I mislead some of you. So yeah, *stops*

Geography Remedial Lessons: OMG! LFL TEACHES GEOGRAPHY?! *too stunned to be listening in class*

well, that ends the mark of revision in school~
