Project Summary

Products on the market usually come in lovely packaging to attract customers to buy them. The packaging of these products may account for a fair portion of the cost of the products. Furthermore, most of the packaging is thrown away after the products are opened or consumed. Excess and non-recyclable packaging adds to our energy and waste problems.

Repackaging products with excessive packaging using less and recyclable materials will help in protecting our environment and conserving resources and energy. We propose to look at ways to cut down on the amount of packaging of selected products, yet making them attractive to potential customers at the same time.

Our group went to supermarkets to look for products that use a lot of packaging. We shortlisted these products :

i) Strawberry Marshmallows
ii) Hong Da Coconut Biscuits

We brainstormed ways to re-package them. One of the main materials we decided to use is plastic bags with grip seals as they are not only resealable, but are also reusable.

After we had repackaged the products, we conducted a survey among our schoolmates and good responses eg. Nice packaging, impressive, attractive and etc.

Project Summary

Since oil pollution is one of the major pollution problems and my project consists of an oil filtering system which is able to eliminate or prevent the oil spillage into the sea. I chose to use a maze for this project called "Oil Filtering Maze".

The prototype is design as an anti-oil pollution filtering system in order to eliminate the oil spill and to prevent the oil pollution problem of Marine Environment.

The 'Oil Filtering Maze' consists of three plastic compartments, the first compartment consisting of felts called the 'Felt Filter'. The second compartment consisting of sand and the third compartment consisting of small pebbles and bigger stones. Finally, the water flowing out from the oil filtering maze will be freed from diesel oil.

Each of the compartment is connected to each other using PVC pipes. Two intersection points or otherwise known as valves are connecting the pipes together.

Lastly, these valves are installed to open, close or control the flow of oily water.

Project Summary

As Life Science ambassadors we are constantly trying to improve our facilities at or Eco-garden which is our Centre for Life Sciences. We look after the plants and animals there and sometimes we meet to brainstorm for ideas. It was during these sessions that we thought of the eco friendly eco-garden.

We have a massive eco garden. It includes a rainforest themed area that consists of a eco-pond and a fernery, a vegetable plot area a butterfly garden and plant nursery. We have over 450 species of plants growing in these areas and watering the plants is not humanly possible because of this large area.

The plants are watered by a sprinkler system and it is runs on batteries and the supply of water comes from PUB. We plan to create a water recycling plant so that water required for the sprinkler system will come from this facility. We also plan to create a solar panel so that the sprinkler system will run on solar energy.

Furthermore, with the solar panels working in sync with the water recycling plant, it would nake the garden completely green and environmentally friendly making it easy for students to learn and understand environment issues and its applications under one roof.

Project Summary

Long term water availability in both global and local context will be curent and future challenge to the survival of mankind. One can maximized water resource usage by reducing pollution of with nitrates runoff is one of them.

The project serves to investigate into a novel means of housing potted plant in a holding device that allows for "recycling or reused" of the water and its dissolved nutrients so as to maximize water usage and to reduce environmental pollution. Water runoff rate and nitrate leaching rate from vermiculite containing self construct pots were carried out. The average water runoff rate is around 71.3 ml for every 100 ml of water added per watering per day. Nitrates leaching rate is constant at 40 ppm for a succession of 5 runoffs in the same day. Impact of nitrates and recycling on plant growth were also carried out on Balsam plant for 4 weeks. Plants growth without fertilizers were possess yellowish leaves while plant grow with fertilizer and subsequently maintained by recycling the nitrate-rich runoff water develop green leaves with a height of 5.5 cm compared to that of the control at 4.8 cm.

The experiment illustrate that by using the novel pot for housing potted plant is able to reduce water usage and maximize nitrates hence resulting in reduction of environmental pollution by fertilizer's leaching.

Project Summary

Instead of using electrical energy or electricity to cool down a place by using an electric fan or air conditioner, we are using nature to do the work. The principle of this project is plants give out water to cool themselves by a process called transpiration. During transpiration, plants give off minute water vapour. When we stand under a tree on a hot day, we can feel the coolness under it.

Based on this concept we intend to build some structures whereby plants can be planted and placed on the wall. We call it the "Princess Green Wall" our objectives are :

i) to reduce the temperature of a room
ii) to conserve electricity
iii) to save on utility bill

Green Walls increase the aesthetic appeal of a building and can foster community interaction. They provide opportunities for pupils to manage their own garden, teamwork and co-operation.

We build the structures using framed wire mesh for support whereby plants can be planted in recycled pastic water bottles as planting pots.

Project Summary

Singapore's water shortage problem is becoming more and more critical. We cannot ignore it any longer. Singapore has been buying water from Malaysia. However, this is only a short-term solution to the problem.

In 2007, our Principal, Mr Yong Cheng Huat, had a brainwave to help sove the problem when he came up with the brilliant and innovative idea of collecting rainwater in the school and reusing it. It is a modification of Singapore's method of collecting water in reservoirs. Rainwater is collected from the school rooftops for recycling by channeling it into twelve 1000-litre tanks made from recycled materials.

In 2008, Stamfordians were tasked to find different ways to use the rainwater collected, to calculate the amount of water used and the amount of money the school can save each month through the recycling process.

The alternatives for using the rainwater that the New Life team explored were threefold
. Generation of hydro-electricity by channeling rainwater into a school pond
. Watering of plants using mobile tanks
. Flushing of toilets

The school adopted the idea of watering plants using rainwater but not the idea of using mobile tanks. It also implemented the idea of channeling rainwater into two toilet complexes.

Results showed that more than eleven thousand litres of water can be saved each month. In monetary terms, the school may not have saved much, but if other schools also adopt this idea, Singapore can really save a lot of water nationwide. Stamford Primary shares its vision with the nation.
