| Solar and wind powered, clean and clear water Koi-pond |
| ITE College West (Dover) |
| Maung Than Htike, Sim Chien Wei Christopher, Chua Huixiang, Ong Zhan Hong, Koh
Winson, Kung Wei Tai, Richard Ong Fock Chin |
The project involves the design of a Koi Pond that is able to keep
the water clean and clear operated by using solar energy, wind energy and
electricity. There are 2 parts in this project. The first is to design a pond
which makes use of mechanical and biological filtering systems. The second is
to design a system that is able to supply the electrical power to operate the
pumps used in the filtering system. This requires the students to apply
different technologies and skills, including design, teamwork, technical and
programming skills.
The purpose of this project is to cut down the usage of electrical power supply
being used. The submersible water pump used in the filtering system will
operate using three types of electrical supplies solar energy, wind energy and
the main electrical supply (240V, 50 Hz).

| The usage of polymer blocks to reduce silt in water discharge |
| Nanyang Junior College |
| Farhana Mehnas d/o Haja N, Oei Shu Xian, Sih Wei Sing |
Our project aims to reduce the discharge of silty water from
construction sites into marina barrage by the use of polymer blocks. Our
hypotheises is that these polymer blocks are able to cause minute silty
particles to flocculate.
Our group had collected water samples from two construction sites before and
after the polymer blocks were introduced. These water samples were than sent to
Productivity and Standards Board (PSB) for detailed analysis. Analysis of water
samples proved our hypothesis right. Water is a scarce resource in Singapore
and we hope it would not be polluted.

| Abuse-free EZ use toilet tissue dispenser |
| ITE College West (Dover) |
| Hean Chao Xiang, Lim Chuen Han, Neo Sheong Wee |
A simple toilet tissue dispenser will automatically dispense just
enough amount of paper to students upon request. It will prevent the misuse of
toilet tissue paper and also help to create green awareness among the students.
Students can activate the machine by using his personal EZ-link student pass.
Upon activation, the machine will dispense a pre-determined length of toilet
tissue paper. The advantage of using the machine for dispensing toilet paper is
that machine will not dispense paper more than 2 successive retrieval in a
single occasion, therefore indiscriminate use and wastage of tissue papers, a
common bad practice, is avoided.

| Cleaning up our soils and waters using plant hyperaccumulators: Which is
best? |
| Anglo-Chinese Junior College |
| Khew Yu Ting Joanne |
This multi-disciplinary project aims to investigate the ability of
local mangrove plants to accumulate pollutants in the form of heavy metals and
metalloids (components of industrial waste) in their leaves. From our findings,
different mangroves are able to accumulate different pollutants with varying
efficiencies. They can thus act as 'biological mops' in saline environments.
Utilizing mangroves to reduce pollutant concentration would improve the health
of all living organisms, prolong the lifespan of seawater desalination
membranes and save cost on pollution control methods. Mangrove plants can also
act as pollution indicators, helping us to identify regions which require
pollution control.

| Smart Air Conditioning System |
| ITE College West (Ang Mo Kio) |
| Fun Soon Cheong Dominic, Tan Shi Yun Sharon |
Air conditioner consumes substantial amount of electricity,
requires ozone-eating refrigerants. The more energy efficient and the less harm
it does to the environment. When less energy is used, less energy is also
generated at power plant, which reduces gas emission and improves the quality
of the air.
This project adopts the method of controlling the air temperature in the room
with the presence and absence of human beings. The prototype itself consists of
solid state cooling system, fan, relay and programmable logic control. For
simulation purposes, the manual control switches are used to replace the
passive infrared sensor for detecting the emission from human body.
The highlight of this project is that upon detection of the absence of the
human being, it will moderate its room temperature to its desired preset
temperature, preferably at 25 degree Celsius.
This is especially useful when the office executives tend not to switch off or
adjust the air temperature when they leave the office for a short and long
period of time.

| Wormi vermi |
| Catholic Junior College |
| Alfred Chan Cheuk Fung, Ng Zhong Ming, Derrick Tan Wei De, Melissa Low Yu Xing,
Dax Lau Jun Keat, Lie Meryline |
By using earthworms and a composting kit, we intend to produce
"vermicasts" a.k.a. broken down wastes as organic fertilizers which are
environmentally friendly. We will prove how easy it is to adopt such a system
and encourage Singaporeans to actually kill two birds with a stone; recycle
kitchen wastes as well as preserve the soil with organic fertilizers.

| Humic acids in water treatment |
| Nanyang Junior College |
| Leong Sok Fong, Htin Aung |
The project is about removal of humic acid from water. Certain
humic acids are believed to be casinogenic and detrimental to human health.
Little emphasis is placed upon the removal in the current water treatment
process as its effects are not widespread. Background researches have shown
that humic acid could be removed using Titanium dioxide. Our research (in NTU)
involves determining the optimum conditions for removal of Humic Acid. In the
project, we will also propose on alteration that could be made to current
water-treatment plants so the removal of humic acid could be incorporated
without having to rebuild existing plants.

| Study of properties of incineration fly ash in ternary blends |
| Nanyang Junior College |
| Chew Jie Bin Elroy, Chee Cheng En Kelvin |
This project aims to determine a new generation of cement mixture
for building purposes. A mixture that re-uses burnt wastes, in the form of
ashes, from incineration plants in Singapore. Various types of invaluable ashes
were used to produce combinations of cement mixture where tests were conducted
to find out their strengths and weaknesses. This cement mixture has a hope to
fulfill the needs of those who seek cheap, as well as durable cement paste for
the construction of buildings.

| Smart rainwater collector |
| ITE College West (Dover) |
| Chong Yuen Keat, Ian Hong Wei Zhi, Prashanth Kumar |
This project is about designing and developing a device to collect
rainwater 'smartly' at home. Rainwater collected is used to clean homes, cars
and water plants, etc. Thus it reduces portable water usage and provide better
nature resource management. It consists of a micro-controller, PCB, Rain
Sensor, foldable tray, pressure switch, storage tank, two servo motors, etc. It
was designed to mount on laundry polls. When the rain sensor detects rainwater,
it will feedback to the microcontroller to activate the servomotors to open the
foldable tray to collect rainwater. The water collected is drained into a
storage tank. In order to make the device smart, the foldable tray will close
when the rain has stopped or the storage tank is full.
