Unfortunately, I have not been updating this place as much as possible, so I will simply post another update right now.
I have completed my science ACE activities (finally!), after much needed research and time put into doing it.
Over a period of one week, I was able to do the following for grades:
- Do TWO PowerPoint documents: one on asexual reproduction, and another on evolution.
-Visit the Singapore Botanic Gardens, AND get many photographs to use in a reflection.
It wasn't easy, as I had to research for hours on end. However, it was worth the effort.
Also, for the third term this year, I got an A1 for science... again. I must admit, it wasn't easy either, considering biology involved a lot of remembering and mugging. Still, it was all worthwhile.
So long, viewers!
Hi to all who are viewing my posts... feel free to explore.

Science ACE assignment - Primary colours
To supplement my ACE points, I also chose to do an assignment on different primary colours and how they are used in daily life. I researched on three models - the RGB, the RYB, and the CMYK models. An excerpt from my research is shown, on the CMYK model, used in printing.
·
The CYMK model is the last one of the
commonly known models of primary colours.
·
This acronym
stands for Cyan,
Yellow, Magenta,
and Key (which means black ink).
·
This format is usually utilised by printing
and publishing businesses, and when printing out documents and images from a
conventional printer. Though the print quality depends on the press house that
purchases the ink, the printer being used to produce the text or image, and the
type of ink used for printing, the ink is usually applied in the order the
acronym follows: cyan, followed by yellow, then magenta, then black.
·
This format works
by partially or entirely masking the above colours in the afore-mentioned order
onto a lighter background, usually white. The coloured ink thus reduces the
amount of light that gets reflected from the paper.
·
Hence, it is
known as a subtractive model, as it “subtracts” the amount of light that gets
reflected off the paper.
·
The difference
between this format and the additive “RGB” format is that while white is the
combination of all colours in the RGB format, and black is the absence of any
colour, the “CYMK” format has white meaning that there is no colour at all, and
that black is the compilation of all the colours.
I This is gon' be my last update for now, so I'mma go offline. Dude007 is out, peace!
Science ACE report on the telescope
This is another assignment I did for the purpose of gaining ACE points - I did this report on the telescope.
Today, modern telescopes include radio
telescopes, which make use of radio waves to create images; X-ray and Gamma ray
telescopes, which utilise X-ray optics to perceive images of subjects; and the
Hubble Space Telescope, which is a large Cassegrain reflector telescope that
has been orbiting the Earth since 1990, and has secured its reputation as one
of NASA’s most successful missions ever.
Enjoy!
The telescope is an instrument widely
used by many people of different professions, from sailors to astronomers.
Telescopes are crucial tools in the jobs of these people; their main purpose is
to observe remote objects which are far away from the user or not even visible
to the user at all.
The word telescope has its origins in Greek; it is a combination of the
words tele,
(tele,
meaning “far”) and skopein (skopein,
meaning “to see”). In the Greek language, the word telescope literally
translates as “far-seeing”. This word was coined by the Greek mathematician Giovanni
Demisiani, as a name for one of Galileo Galilei’s magnifying instruments.
The invention of the telescope dates back to
1608, in the Netherlands, when Hans Lippershey and Zacharias Janssen, spectacle
makers from Middelburg, created telescopes based on the theory of
refraction.
Hubble is expected to last
until 2014, and then it will crash back to Earth. In 2018, it will be succeeded
by the James Webb Space Telescope, a powerful infrared telescope which has only
one main purpose: to see far into the deep recesses of the universe and uncover
more secrets in the dark void.
Thus concludes my report,
which covers the origins of the telescope, to the great telescopes in space
which we operate and utilise to their full potential today.
Of course, this is not the whole report; it is actually much longer, and has images, like the one above.
More to come soon!
Reflection on trip to science centre -Term 2
To all viewers, this post has to do with a visit I made to the Singapore Science Centre in May... enjoy.
I
chose to visit the Science Centre on Labour Day as it was the only free day I
had, and also; I could have more time to explore the interior.
When
I got there, I decided to take my time with the exploration, as I realised
there had been major renovating going on since by last trip, and the whole
interior had been revamped. Also, there had been major changes to the layout of
the exhibits, and though they still contained the same exhibits, they had been
rearranged in such a way that the area now looked completely different from my
previous visit.
I
started with the ground floor, and visited the exhibit on bioethics. This
exhibit is dedicated to environmental studies, such as pollution and
destruction of habitats. Also, it displays information on weather conditions
and natural disasters, and how they occur. Also, there was an area reserved for
human anatomy, and another upstairs area for virology. The section on human
anatomy was particularly interesting, as it talked about how people find each
other physically attractive, and the psychological factors behind this. For
example, I found out that when a person deemed physically attractive is shown
alongside another, less attractive person, the former is also deemed to be
physically unattractive.
The
segment on virology was particularly disturbing, despite the weird and funny
cartoon depictions of various viruses such as HIV, SARS, and Hepatitis B. This
was most probably due to the fact that alongside the animated versions of the
viruses, there were many samples of statistics displaying how the viruses are
spread, and the symptoms. They were quite frightening, especially the physical
symptoms of smallpox, which displayed many raised welts and pustules on an
infant’s body and face.
Another
sector of particular interest was the exhibit on sound. They had completely
changed the various activities, and now the exhibit included a hollow tube that
produced echoes when sound traveled through it (which I tried). I realised the
echoes produced by the tube were exceedingly clear, and not like the echoes
produced by sound bouncing off a natural wall.
Finally,
the main atrium branching out to the other subsections of the Science Centre
had one new exhibit, which was a tornado exhibit. Up until this time, I had
only read about hurricanes and how they had a calm area in the centre, but I
never expected to learn that the exact same occurrence was present in tornadoes
– the centre of the storm is where the winds are calmest. I also tried a
chamber they newly installed which was related to tornadoes – it simulated the
wind conditions inside a hurricane. I almost died from the sound; it was
exceedingly deafening.
Thus
concluded my personal field trip to the Science Centre. It was short; albeit
informative. I learned much from this visit, mainly because of the newly
revamped exhibits, which made learning more comprehensive and enjoyable.
More stuff coming up soon... stay tuned.

Another update
Haven't been updating lately due to some issues regarding piling up of work and me not exactly taking initiative... will post some new stuff soon.
New science teacher has just started on the biology segment of our science curriculum, and I am currently having major problems memorising and putting into use whatever has been covered into assignments and projects; I am currently in the middle of a group assignment with several of the people I don't exactly like at all. Just got to put up with them for a few more days, and it will all be over.
Going to put up all the stuff done in Terms 1 and 2 when I'm not so busy, most probably next week.

My latest update so far
Yo people, sorry I've been a little behind on updates... so I will try to squeeze all the stuff from the first semester in 2012 as soon as I can. Before I conclide this post, I will now broadcast my results for science for this semester.
I got A1 and A2 respectively for my science tests this semester. This came as quite a shock, as last year, my science results went crazy last year. They really dropped drastically. Hence, I was glad that all the extra mugging did not go to waste.
Will try to update more frequently, so stay tuned. Dude 007 is out, peace!
