Science practicals and teamwork
Last term (term3), i did science practicals with my classmate Wei Yang rather than Zhi Hao because my teacher changed my lab partners. However, wei yang and i made very slow progress when doing our practicals where he or i would go to watch some other group do their work because we were not sure how to do the practicals as physics is the worst of our three sciences for the both of us.
However, i think our teamwork nearer to the end of the term improved quite a lot as at the start we were always one of the last to leave the science lab as we took so long to complete the worksheets. However, later on we manage to complete the experiments rather quickly and finish up the related worksheets and managed to be finished on time.
I think that teamwork is very important because it lets people work efficiently in a group and get things done quickly.

MacRitchie reservoir outing (Reflection)
Last term, my class went for a outing that had to do with science. We went to the MacRitchie reservoir to learn more about things there. These stuff included things like plant life where our teacher then told us about some of the more interesting plants. Furthermore, we also went to a walking path where our teacher showed us some plants and insects that had some interesting characteristics.
i think that the field trip was very fruitful as even though all the walking around was very tiring, i had learnt many new things that day, mostly about ecology as the aim of the outing was to teach us more about ecology.
Since we learnt many things during this field trip, i would recommend that my school could organize it again for other class that did not go because only the sec2 classes went for this outing.

Reflection: The science to preserving Terracotta warriors
Earlier this term, my group did a presentation on the science behind preserving the condition of terracotta warriors that were excavated in China. we found out that there were two ways to preserve the terracotta warriors.
while i am not going into the process of preserving the terracotta warriors, i think that learning how to preserve terracotta warriors is a very interesting science process. This shows that science is not only about reading test books and studying notes too prepare for your exams but about other things as well such as discovering new things about this world.
I hope to have sabbaticals like this one where we learn about new things and get to put our thinking and group skills to the test.

Reflection for Term 1 science test
For term 1 i had gotten 30.5 which was a very close A1. I think that getting an A1 was quite good even though i was disappointed that it had not been higher because some of my other classmates had gotten very low scores and did badly for that term (like how i got a bad MSG for term 3).
Overall i think that when i study for my end of year exam i should focus a lot more on the physics topics as i think it is my weakest out of the three sciences. I also think that i should revise more on the chemical reactions of compounds and elements as sometimes i am not sure what is the outcome when two things react which could lose me some marks in my exams.
I hope that i will get an A1 in my exam as i am hoping to take triple science next year and while physics and chemistry is already compulsory, Biology needs good science results as well as an MSG of 2.5 and below.

Let's Eat!...genetically modified salmon
The salmon has been the first animal to be approved for genetic modifications. even better the genetic modification allows the salmon to grow to meal size in half the time that a normal salmon takes, meaning more salmon will grow to eatable size more quickly to sustain our population.
Unfortunately, this genetically modified salmon has encountered criticism and threats of lawsuits from consumer organizations even though it has been shown that the salmon does not affect human health in any way and is completely safe to eat.
While people argue that the consumer organization needs to consider the fact that encouraging farm bred fish (the genetically modified salmon) will boost the aquaculture industry. This might make the price of salmon cheaper and encourage people to buy more salmon rather than other types of meat which would then give them a more healthy diet. The only downside is that the population of wild fish that is needed to feed the salmon may diminish in number.
either way, the genetically modified salmon will not be the first FOOD to enter a consumer's mouth. it seems that there is genetically modified substances in our corn chips. *_*

The world's second largest virus has been discovered! (As if we didn't need more trouble =-=)
This huge virus has been dubbed CroV by the scientists that discovered and is currently known to only infect marine life that are also single celled organisms.
The reason why this virus is so huge because of the number of genomes that it contains. 730000 base pairs or genetic building blocks as some people call them. Normal viruses usually have far less than that with the largest known 'normal' virus only containing slightly less than half of the number of genomes CroV has.
Not only that, because the biggest virus, Mimivirus (has 1.2m base pairs) is only distantly related to this CroV virus, it suggests there are more huge viruses. Scientists who have been examining the CroV virus have found surprising things. Mainly that the virus (and other huge viruses) has genomes that allow to have features to have similar to cells.
due to thus, some scientists are arguing that a fourth domain of life should be declared for this huge viruses. This is because viruses share a common set of genes with cells as well as obeying the same laws of physics as any other cell.

Science Results: Term 2
(i am doing my science term reflections in backwards order)
In term 2, i had gotten 29.5/40 but due to a moderation of the test paper the overall score of the test was reduced by five marks with our own scores not being reduced. Thus my actual score for that term was 84. i think that this might have been what made me over confident for the third science test for this term as i thought i would get around the same score. T_T
i think that i should work harder for the end of year because my current average for science is still a bare A1 and at the end of the year i want to have science as one of my A1s. While i am hoping that i may have a chance for an exemption i think it is unlikely so i should study first.

WOW FREE INTERNET ACCESS?!
This man, Kosta Grammatis aims to buy a satellite for developing countries where he believes they do not enjoy internet as a luxury of the 21st century.
If he manages to buy a satellite(his target acquisition is the Terrestar-1 satellite), he plans to move the satellite into a position over a developing country. The satellite can then give free internet access for all of the people in the country and if the satellite signal is strong enough, people in other neighboring developing countries can even use the internet as well!
His organization called A Human Right, is currently looking for donations to get 150000 dollars in donations through the online site buythissatellite.org so it can put together a business plan. (SO DONATE NOW!^_^) Kosta is also trying to find a big company such as google to back his plan.
If his plan succeeds many people in poorer countries will be able to use internet.

Invention review: Glass Nanobots
There currently is a new invention to help clean our sea water and it is the Glass nanobot. This invention can take contamination in the water and bind it to themselves. While this makes them similar to sponges, what makes them better for absorbing contamination from water is that they do not absorb water as well, making them absorb more contamination.
Furthermore, these nanobots are reusable so when they have absorbed contamination to its maximum capacity, they can be taken out of the water, cleaned then replaced to absorb even more contamination.
The inventor of this product aims to use it to clean contamination that is in our seas, in our water supply and other places where contamination may come into contact with water.

Invention review: Bio-Printer
For people who do not know what is a bio printer, it is "prints" human cells in a three dimensional matrix to be assembled into complex organs or blood vessels.
Currently, the company states that the bio printer that they had invented is currently only able to produce all types of blood vessels as our technology is not as advanced to be able to real complex organs like stomachs and livers. However, a partner company, Invetech that helped the company, Oganovo to produce the bio printer believes that they will be able to upgrade the bio printer to be able to produce actual organs.
I think this is a fantastic invention because the organs that are produced can be used to save people that are in of an organ transplant but there are no more organs to be had. With this kind of technology that is able to produce organs for people, we will be able to save many more people in hospitals with organ failures and other things.

Invention review: Invisible Shield
This year, there has been an invention called the Invisible Shield. Now this amazing invention can be coated on almost any kind of surface and be unnoticeable as it so thin, only a 100 nano meters thick (500 times than thinner than a human hair).
The inventor of this Invisible Shield claims:"This latest science invention is a spray-on invisible thin glass coating that sterilizes, protects and strengthens surfaces.
The coating also repels water, dirt, stains, mildew, fungus, bacteria and viruses."
when he was asked how people would be able to wash the object coated with this Invisible Shield, it turns out that he also has a solution to this problem. They can simply wash the object with hot water. This is because the Invisible Shield is made up of liquid glass and only needs hot water to be even more clean than if it was cleaned with bleach or other cleaning substances!
This invention is due to be released later on this year.

My term 3 test results for science
I got 25.5/40 for this term for my science test. which is very lousy compared to my other scores for the first two terms.
I think it might be because i took the test too lightly as i thought i would be able to score reasonably well based on my other test scores. However, this term was testing physics and i have noticed that the terms where physics has been tested i have done badly for the whole term.
when i got back my test result, i calculated that my average score for science it was still an A1 so i am hoping that i may be exempted from science this.

An ace project, a tour in space
So, for term 3 i did a ace project where it is about an alien that goes around in our solar system trying to find a hospitable planet to live in (excluding Earth cause they are peaceful aliens and don't want to kill us). Here is his report. Enjoy!
Robb the alien's tour of space
Introduction: Robb the alien was sent from the galaxy Andromedea to investigate the Milky Way for habitable planets. While he was investigating, he found our tiny solar system and made a report of what he found. He has dubbed our solar system Milky.
Basic things that can be found in Milky:
1. The Sun - The Sun of Milky is a small star compared to other stars that i saw in other solar systems but it is still gigantic compared to the planets orbiting it. I have predicted that this particular Sun will be burning out within 5 billion years.
2. Milky's Planets - Milky has only 9 planets with one being a tiny dwarf planet. Disappointing, in my own solar system there are twice the amount of planets in Milky. They are far bigger as well.
3. Moons - i found some moons orbiting some of Milky's planets such as the Earth where i found a moon.
4. Comets - These are balls of ice and rock that orbit the Sun on the edge of any solar system. I enccountered some of them when travelling Milky's planet and Sun but it was no trouble for my spacecraft to avoid.
Milky's sun and planets:
1. The Sun - At the start, like all other stars, Milky's Sun was just another big cloud of floating gas and dust in space. i have hypothesized that another star passing by gave the cloud a nudge and then it started pulling gas and dust into a ball to growing larger and larger till it is what we see today! The sun is powered by helium which the Sun produces by having enough gravity to crush its hydrogen gas turning it into helium.
Interesting things to note -
The sunspots which are holes on the surface of the Sun made by magnetic forces.
solar flares that could damage the Earthlings primitive electrical equipment. (More on earthlings and their planet later.)
Meanwhile, while the Sun was forming, what would be the nine planets were also forming......
2. Mercury - The first planet in Milky it is a very close distance to the Sun, only a mere 58 million km a short distance for my spaceship. After inspecting it, i have very easily concluded that the planet is uninhabitable due to having no carbon dioxide for us aliens or any oxygen for Earthlings. Furthermore, the temperature change is so drastic i doubt that anyone can adapt to it!
Mercury's statistics - (statistics are in earth measurements)
Size: 4900km across
Moons: None
Length of Day: 58.5 Earth Days
Length of Year: 88 Earth Days
Atmosphere: Almost no atmosphere at all
Temperature: 427 Celsius in the day and -183 Celsius at night
Interesting to note:
The Caloris Basin - a crater that is 1300 km across slightly more than one quarter of Mercury's diameter, A HUGE LENGTH!
3. Venus - After inspecting Mercury, I flew on to Venus which was 50 million km away from Mercury. To my disappointment, Venus was also uninhabitable. While the heavy carbon dioxide atmosphere suited my kind perfectly (though not the earthlings), the clouds were so full of acid that even we cannot withstand it. I have concluded that trying to inhabit this planet is suicide.
Venus' statistics -
Size: 12100 km across
Moons: None
Length of Day: 243 earth days
Length of year: 255 earth days
Atmosphere: Heavy clouds of carbon dioxide gas
Temperature: Constantly around 500 Celsius
Interesting things to note: NIL
4. Earth - At last, i found a habitable planet. Unfortunately, a dim witted race whom i have called Earthlings have already overrun the place using up resources that we sorely need. I will have to search for another habitable planet.
Earth's statistics -
Size: 12700 km across
Moons: one
Length of day: 24 Earth hours
Length of year: 365.25 Earth days
Atmosphere: 78% Nitrogen, 21% oxygen as well as other gases including carbon dioxide which makes up 0.5% of Earth's atmosphere.
Temperature: Hot in the middle of Earth's surface and freezing at its poles.
Interesting things to note:
Earth is mostly covered in water. A whopping 71%, so much water could sustain our race for years. (Unlike Earthlings we can drink salt water too.)
Earthling scientists have invented something called an Umbrella that keeps out rain. This could be useful for our own race as well.
5. Mars - Unfortunately, Mars has no atmosphere at all except for small wisps of carbon dioxide, not even enough for my race to survive on. however, I must admit that there was some superb sites on this planet.
Mars' statistics:
Size: 6800 km across
Moons: Two (Deimos and Phobos)
Length of Day: 24 Earth hours and 37 minutes
Length of Year: 687 Earth days
Atmosphere: tiny wisps of carbon dioxide
Temperature: -30 Celsius
Interesting things to note:
The Mariner Valley - The Valley is 6.4km deep and 241 km and is the biggest and vastest valley in the whole of Milky. A grand sight indeed
Mons Olympus - This is Milky's highest mountain. Standing at a height of a staggering 25km and spanning 483km in width, it is three times as large as Earth's biggest Mountain.
6. Jupiter - Jupiter is a gas giant and may well be habitable for us Martians. While hydrogen is not the most healthy gas for us to live on, it is better than having to breathe in other gases. Unfortunately, we will need to contruct our prototype flying buildings as there is no solid ground to live on. The flying buildings will also help us to withstand Jupiter's radiation and gravity.
Jupiter's statistics:
Size: 140000km across
Moons: Four big ones and many little ones that are in reality only asteroids pulled into orbit by Jupiter's gravity.
Length of Day: nine Earth hours and 51 Earth minutes
Length of year: 11.8 Earth years
Atmosphere: mainly hydrogen with a bit of helium.
Temperature: -163 Celsius to -121 Celsius
Interesting things to note:
There is a storm in Jupiter called the Great Red Spot and it is a huge storm that has been blowing for 300 years, amazing!
7. Saturn - This planet has been rendered inhospitable by such fast winds. These winds reach up to 1800km an hour.making it impossible to even try to contruct our flying homes. However, with advances in technology we may be able to inhabit this planet.
Saturn's statistics -
Size: 120500km across
Moons: At least 22 over 20km in size. there is also a huge moon 5150km called Titan.
Length of Day: 10 earth hours and 38 minutes
Length of Year: 29.5 Earth years
Atmosphere: Hydrogen and Helium, similar to Jupiter's atmosphere.
Temperature: -191 Celsius to -130 Celsius
Interesting things to note:
Saturn's rings are beautiful from a distance and these thousands of rings is made up of shiny bits of ice and rock.
8. Uranus - As with saturn, uranus has very strong winds though no where as close to Saturn. With winds travelling at a speed of 300km an hour, it will only be a decade before we have put in functions for our flying buildings to be stable in the air. Though the methane level in the upper clouds will require us to live below where there is only Hydrogen.
Uranus' Statistics -
Size: 52000km
Moons: Five main moons and 15 smaller ones
Length of Day: 17 Earth hours and 12 minutes.
Length of Year: 84 earth years
Atmosphere: Hydrogen with a bit of helium. There is methane in the upper cloud levels.
Temperature: -214 Celsius to -202 Celsius.
Interesting things to note:
Rather than spinning, it tumbles heads over heels making it the only planet that does so.
9. Neptune - This planet is not inhabitable. The winds of these planets are so strong that they are faster than Saturn's! And i thought winds couldn't get any faster than such a high speed. Neptune's winds travel at a whopping 2000km and hour and as such will not allow us to live here.
Neptune's statistics -
Size: 48000km across
Moons: seven tiny ones that are dwarfed by a large moon called Triton which is 2705km across.
Length of Day: 16 Earth Hours and 6 minutes
Length of Year: 165 Earth years.
Atmosphere: Mostly hydrogen with some methan and helium.
temperature: -223 Celsius to -200 Celsius
Interesting things to note:
Neptune's moon Triton, is the only moon to spin in the opposite direction from its planet's orbit.
10. Pluto - Pluto is so cold that when it is farthest from the Sun during its orbit, the whole atmosphere will freeze and fall to the ground. WOW! Definitely unhabitable.
Pluto's statistics -
Size: 2300km
Moons: Charon. The moon only takes one pluto day to go around Pluto so if you were on Pluto, the moon would always be in thee same place.
Length of Day: 6 Earth days and 10 earth hours
Length of Year: 248 Earth years
Atmosphere: A bit of methane and nitrogen
Temperature: -238 Celsius to -228 celsius
Interesting things to note:
Pluto has been named a dwarf planet as its planet size is very small. Furthermore, Pluto's moon is almost the same size as pluto.
Conclusion: We have come to the end of Robb's report and he hopes that everyone can learn something from it.

Though the methane level in the upper clouds will require us to live below where there is only Hydrogen.
Uranus' Statistics -
Size: 52000km
Moons: Five main moons and 15 smaller ones
Length of Day: 17 Earth hours and 12 minutes.
Length of Year: 84 earth years
Atmosphere: Hydrogen with a bit of helium. There is methane in the upper cloud levels.
Temperature: -214 Celsius to -202 Celsius.
Interesting things to note:
Rather than spinning, it tumbles heads over heels making it the only planet that does so.
9. Neptune - This planet is not inhabitable. The winds of these planets are so strong that they are faster than Saturn's! And i thought winds couldn't get any faster than such a high speed. Neptune's winds travel at a whopping 2000km and hour and as such will not allow us to live here.
Neptune's statistics -
Size: 48000km across
Moons: seven tiny ones that are dwarfed by a large moon called Triton which is 2705km across.
Length of Day: 16 Earth Hours and 6 minutes
Length of Year: 165 Earth years.
Atmosphere: Mostly hydrogen with some methan and helium.
temperature: -223 Celsius to -200 Celsius
Interesting things to note:
Neptune's moon Triton, is the only moon to spin in the opposite direction from its planet's orbit.
10. Pluto - Pluto is so cold that when it is farthest from the Sun during its orbit, the whole atmosphere will freeze and fall to the ground. WOW! Definitely unhabitable.
Pluto's statistics -
Size: 2300km
Moons: Charon. The moon only takes one pluto day to go around Pluto so if you were on Pluto, the moon would always be in thee same place.
Length of Day: 6 Earth days and 10 earth hours
Length of Year: 248 Earth years
Atmosphere: A bit of methane and nitrogen
Temperature: -238 Celsius to -228 celsius
Interesting things to note:
Pluto has been named a dwarf planet as its planet size is very small. Furthermore, Pluto's moon is almost the same size as pluto.
Conclusion: We have come to the end of Robb's report and he hopes that everyone can learn something from it.
