reflection term 2 week 2 by kah hon
This week we presented our survey results to a rather less than interested audience. Never the less I belive that this week was well spent.
Reflections term 2 week 2 by Xu Kai
Today, we finish our survey presentation and got a good score. Anyway, we have finish our final product, the solar car and so, we can relax! Yipee! With the task finished, we can have a load off our mind. Our teacher says that our presentation is quite well done as the questions is sensible and linked.
reflection term 2 week 2 by Alex
Hey, everyone! I am back from the march holidays...had a fun time. Anyway, we just presented our powerpoint slides to another group.Our teacher say that it is better than another group. YAY! We just decided that our final product will the solar car and we finished it already

reflection week 7 by Alex
today, we did only this reflection because the teachers did not want to give us any stress as the common test is coming and we need to study hard. Good Luck!
Chan Hao Xian Week 7 Reflections
Today, we completed the survey, because of the exams, the teachers didn't give us much work to do.We will be giving out the survey for our class to do soon.
Weekly Progress Report by Chan Kah Hon(Week 7)
Hello again and thanks to all who read this!! Especially if you are genuinely concerned about our precious earth.
This week, the other champions and myself managed to draft the survey but have yet to officially roll it out for the public. We aim to release the survey in a few days and then obtain and collate the results of the survey by the end of this week. That is of course an objective though. Whether we achieve that objective has yet to be seen.
Stay sharp fellow Earth Friends!
Signed,
Champion Chan Kah Hon
Reflections on week 7 by Xu Kai
Our group have finished the survey and is on the way to give out the survey forms to tell us how much you know about photovoltaic cells and global warming. Tell you something, we are finishing the whole project soon. Do give in more of your comments that you have for us.
Cheers!

Reflection week 6 by Alex
Today, we did some brainstorming for the survey we will be conducting. It turned out pretty well, I guessed, as we all contributed some excellent questions. We will post it after we tally up the numbe rof people answers. So STAY TUNED!

Chan Hao Xian week 6 reflection
This week, we made a survey which will be done by our classmates to see how many of them understand about solar cells and global warming. The survey will be given to our class next week, and we will know how many of them understand about solar cells and global warming
reflections on week 6 by Xu Kai
This week, we will be planning the survey questions and please give us your support by filing in the survey we are going to give you. The survey will ask you some questions about solar energy and global warming. The solar car will cost us $60++. We hope to hear more valuable comments from you.

Weekly Progress Report (Chan Kah Hon) (Week 6)
Hello fellow Earthlings! Here is my weekly report for week 6 of our project.
This week me and my fellow champions were in the midst of developing a survey that we wish to roll out next week. Hopefully this time our plans will be executed perfectly and without the problems that usually accompany our team...
Cheers!

reflection week 5 by Alex
Hi there! Today we did nothing much except the taking stock worksheet and we decided not to take up the solar boat competiton as there was not enough time to build the boat and common test 1 is coming.
Reflection on week 5 by Hao Xian
This week, our group did taking stocks, and Alex decided not to enter the solar boat competition, because of exams. This greatly annoyed me as I always hate it when exams interfere with my activities.
Weekly Progress Report (Week 5)
Hello fellow Earth Warriors! Here is the weekly progress report.
This week, we, the Champions of the Earth, discussed whether to go for a solar boat course organized by the Singapore Polytechnic. Unfortunately, after long rounds of debating, we decided to forgo the course and pursue other avenues of research. I hope that next week will be more fruitful.

Reflection week 4 by Alex
Today, we were ask to discuss the product we plan to do as a final product. When Mr Goh came into the classroom, he gave me a paper about a competition organised by Singapore Polytechnic. It is a competiton for solar energy powered boat. In the meantime , we are still considering about it.
Weekly Progress Report (Week 4)
This week I managed to compile two reports, one on the disadvantages of solar energy and the other on the issue of solar cell efficiency. These two reports were very important in our cause of developing solar energy. In addition to that, our group convened yet again at Lab 2H for another brain-storming session although with little result. I hope next week will be better.

In week 4, I have we have done the worksheet. Also, our team is considering to participate in the Solar Boat Challenge organized by Singapore Polytechnic.
reflection on week 4 by Xu Kai
In week four, I solve the questions given by searching the internet for information. I learn about the efficiency of solar power and why solar cars are still not up on sale.
Disadvantages of solar energy, a report by Champions of the Earth
Hello fellow tree-hugging hippies! I have some very disheartening news for you all. Most of you think that solar energy is the solution for clean energy or at least hope it will be. Unfortunately it will take at least a few years more of research to make solar cells more efficient. Here are some of the reasons we came to this conclusion. They are all compiled in the following report. Enjoy!
Disadvantages of solar energy, a report by the Champions of the Earth.
Are there any real disadvantages to solar energy? Or, are the drawbacks of solar energy simply news stories planted by the the auto, oil and energy industries. Without a doubt, if there is a real push to develop and use alternate forms of energy, these industries will have the most to lose. Let's look at the top three anti-solar arguments we hear repeatedly:
1) Expense.
Many articles point out the expense of starting a new solar-energy industry but this argument is patently ridiculous. Never in our history has expense been an excuse to avoid new technology. Did people reject the idea of of wiring cities with electrical and telephone lines because it was too expensive? Did we reject the idea of television because it was more expensive than buying a radio. Of course not.
New products and technologies open the door for new companies and entrepreneurs to bring their wares to market and allow the law of supply and demand to take over. Even better, new solar energy industry will create new local jobs. When employment rises, the economy becomes robust and more people will be able to afford alternate energy sources.
In areas with excessive sunlight, homes can be switched to solar energy and families can simply apply the money spent on excessive electricity bills each month toward a payment plan on their news solar equipment. At some point the equipment will be paid for in full and they can then save that money every month, year after year. Tax deductions for energy efficient homes features already exists and some lenders already offer savings on clean energy mortgages for homes installed with solar panels.
While public relation firms working for the oil and energy industries pump out anti-solar news stories, the press under-reports all the ways we can save money when switching to solar.
2) Weather, location and night-time hours make impact the availability of sunlight.
Sunlight isn't available in deep space either but NASA has found ways to store power in solar systems on spacecraft. Of course, the too-expensive argument is also used to undermine the viability of solar storage cells. Yet, as the price of oil increases, many of us are already finding it too expensive to heat and light our homes with fossil fuel products and electricity.
Until governments allocate funds to research ways to store solar energy for consistent use, this argument against solar energy will remain. Leaving research up to the existing energy industries is ridiculous. Why would they develop technology and products to undermine the profits they make leaving things as is?
3) Requires large areas of land for municipal solar generators.
This excuse is easy to eliminate. Reallocate the large areas of land currently taken up by existing power plants to solar plants. In the USA and many other countries, huge expanses of desert areas can be used to set up solar plants. We can get creative, because one thing history has proved is that where there's a will there's a way.
The problem is our desire to switch to solar energy is outweighed by our resistance to change. After all is said and done, this may be the biggest disadvantage of solar energy - the desire to maintain the status quo.
Information comes from http://www.helium.com/items/860226-disadvantages-of-solar-energy.
Disheartening as this may sound, I still hope that everybody will not lose faith in solar energy. Just give the tech-heads a few more years and hopefully they can make solar cells more efficient.
Stay strong fellow Champions!

Hi everyone! It's 2H Group 1 again...to update you about our group progress, today which is IPW day( because Day 1 has IPW sessions ), we decided our group topic which is TERRORISM!!! But only group name has not been decided yet, we are still recking our brains about it as we need a name that links with the topic...
Anyway we need to say bye bye already so wait for our next post which should be about our group name.
