A chartitable organization has offered a startup fund of S$999k to any team that is able to come up with an award winning design to build a playground catered to primary school children with special needs. Your playground needs to be inspired by your reading of the novel, Bridge to Terabithia.
You and your team mates (group 5-6) are compassionate budding architects and you have taken up this challenge of designing a creative yet educational playground for these children at your own expense. You may select, from among the following, ONE target group of children to base your desgin on:
a) visually impaired children
b) physically handicapped children
c) children with down syndrome
d) children with non-contagious, but terminal illnesses
e) abused children with emotional scars
You need to do your research on the respective needs of your target group and design the most creative, yet need-sensitive playground and come up with a proposal in order to clinch the deal.
You need to present your proposal before the Present of the charitable organization (aka your Lit teacher) and fellow rival architects (aka your classmates) by the 6th week of Term 2, in the form of a model, alongside your research, sketches, descriptions of functions, proposed materials and budget, and any other relevant details.
You should incorporate ideas which have been insipred from your reading of Bridge to Terabithia, (E.g. Qualities of the secret 'kingdom' that Jess and Leslie were rulers of, how Jess built his confidence in this playland etc) and explain how your reading of the novel has inspired the design of the playground.
This project is worth S$999k, and more importantly, 100% of your SA1.
All the best!

Week 2
The designs for the playgrounds must be safe, as in not to high or children may have altophobia(Scared of Heights) having 'handrails' to pro tect themselves from falling off without noticing, or having slides to up high that even the kids don't dare to get on, or stuff that can be detached and chewed on or eaten bla bla bla.........
The materials must be suitable like the last few posts speaking of proper materials. Since this playground is in the sun, certain factors must be noticed such as the material, like plastic, used carefully as it heats up and when it does, the playground becomes hotter than normal. Certain shelters must also be erected at the playground like a shelter over the slide or swing as not to get a heat stroke, common nowadays.
The designs are still being worked on for the fianl few decisions (still a very long way to go) the designs include mini rock climbings, bridges, ladders, swings, slides, ropes or cross ropes for walking on carefully and climbing, maybe even some seesaws around or round-abouts, still deciding....
We have found some suitable materials such as silicone sponge rubber, haven't yet searched for wood, the SSR (Silicone Sponge Rubber) can stand under the heat well, strong blablabla...... Haven't searched for metals..........Ask Liang Da.........
Everybody trying to get online together at msn at the smae time so won't mess things up to badly and get things started like on the 25th of March when we all got online(almost all) and started to spam all pictures of playgrounds and material items into this blog crazily and made good progress.

Flexible, compressible COHRlastic silicone closed cell sponge is designed for high-performance gasketing, thermal shielding, vibration mounts and press pads.
This product is available in blue, in 36" x 36" sheets up to 3/16" in thickness. The sheets can be purchased with no psa, acrylic psa or silicone psa applied. The self-adhering sheets permit substantial savings because they are easy to apply, simplify production and eliminate the high cost of bonding. The silicone adhesive withstands the same temperature extremes, -100 degrees F to +500 degrees F, as the silicone rubber sheet.
Acrylic adhesive has a temperataure range of -20 degrees F to +300 degrees F and offers the advantage of twice the adhesion to steel and a longer shelf life than silicone adhesive. The self-adhering sheets are protected with an easily removed release liner. Apply to a clean, dry, degreased surface.
R10490 flurosilicone sponge rubber can be used as a gasket where it is necessary to contain fluids that would degrade normal silicone sponge and solid materials (special order basis).
COHRlastic(r) is the trade name for CHR's family of high performance silicone rubber products. Flexible, resilient silicone rubber has a unique chemical structure which gives it a high temperature stability and general inertness unavailable in any other elastomer. As a result, silicone rubber works in applications where no other material can be used.
Thermal Stability:
Silicone's physical properties are not adversely affected by prolonged exposure to temperatures from -100 degrees F to +500 degrees F. In addition, it can withstand intermittent exposure to even higher temperatures. Silicone far out-distances other elastomers in resistance to thermal degradation and outperforms other elastomers in general service life, compression set-resistance, electrical strength and non-stick properties. Silicone also has good chemical and fluid resistance. Although it may swell in contact with some solvents, the rubber will return to its original dimensions, usually without permanent deterioration, after the solvent has evaporated. At elevated temperatures, SGPPL silicone will outgas far less than other silicone elastomers. And, if it should burn, it produces a non-conductive white ash and ordorless, non-toxic smoke.
Inertness:
COHRlastic silicone rubber is odorless, tasteless and non-toxic. It contains no acid producing chemicals and therefore is non-corrosive and non-staining. Silicone rubber has excellent weather-ability because it is unaffected by sunlight, ozone and/or extreme moist or dry conditions. It will not support the growth of fungus. The service life of COHRlastic silicone rubber in room temperature applications is virtually unlimited.
Silicone variations for specific applications.
General purpose silicone rubber itself is versatile material. Beyond that, there are different types available for specific applications.
Silicone rubber compounded from a phenyl base will function down to -130 degrees F, with specialty formulations that will allow -170 degrees F usage. The benefit is greater strength, flexibility and compressibility at those temperatures than could be achieved with the more common methylvinyl compounds. Applications involving high heat and pressure call for a general purpose silicone rather than a high strength variety. Reversion can result from high temperature and pressure, and the general purpose compounds have better resistance to this phenomenon.
When fuel and solvents are present, a florinated silicone rubber is the best choice. This polymer affords maximum resistance to swelling and degradation associated with those fluids.

Why use silicone sponge rubber?Silicone sponge rubber has the combined properties of resilience, high temperature stability and general inertness unavailable in any other closed cell sponge gasketing material. Silicones are generally unaffected by extended exposure to temperature extremes from -100°F to 500°F, and are also unaffected by aging and degradation from sunlight and ozone.

Pentagonea Pentanet made of five tubes and seven ball connectors. Structural frame of the Frameworx system, consisting of steel tubes 60,3 x 1826 mm. Swaged threaded couplers M 20 on both ends are the link to the ball connectors. The assemblage points are built by hollow aluminium balls with a diameter of 250 mm. The fixings are securely fastened inside the hollow balls. The connection points of frame and foundation are rubbercushioned in order to facilitate a maximum of elastic swing for the space cell.

I opt for mulch because it's "natural" - it does biodegrade - and it provides the needed padding.

How To Make It Safe
Make sure all play areas are protected from streets and traffic.
Check the outdoor environment for poisonous plants and remove them.
Check the play area daily. Keep the area clear of glass, litter, and large, loose rocks.
Check play equipment at least once each week. Look for sharp edges, rough surfaces, and loose or broken parts. Replace or repair damaged equipment. Avoid poisonous wood preservatives. Check that surfaces are painted with lead-free paint.
Replace the ground under the equipment with a soft, loose, resilient material, such as wood chips or loose sand. (Cement, asphalt, and hard-packed or frozen soil or sand can be dangerous play surfaces.) Provide the number of inches recommended by the manufacturer. This may be as much as 9-12 inches, depending on the material used. Sand and other loose materials should be raked often to keep them soft.
Carefully consider what equipment is suitable for different age groups. Supervise children closely at all times to prevent misuse of the equipment.
Teach children how to play safely. Involve them in making rules for playground behavior, and enforce the rules consistently. Praise children for using the playground appropriately. Remove a misbehaving child from play and explain how his or her actions could hurt someone.

Literature work. ( Proposal )
Theme : Playground for emotional abused children.
Group members : Rupert, Lynnete, Liangda, Jiayan, Daniel and Zhiliang.
Description about the playground : - Colourful ( bright colours )
- Spacious
- Picture-ful ( smileys, paintings )
- With soft flooring
- Creative ( many facilities )
- Clean
- Low-lying
- Made of soft materials ( sponge, rubber, mulch )
Elaboration : The playground is specially built for emotional abused chidlren. After much discussion with my group members, we've decided on the outline of the playground. It must be colourful, painted with bright colours. Take note that it is bright coloured, not dark coloured as bright colours will make the playground look more lively. The playground must also be spacious so that the children can run around freely. It must also filled with pictures, examples like smileys or paintings done by them. We also must make soft flooring as if the children accidentally fall down, they will not get injured. We also planned to built the playground in a more special way as in more creative from other playground as it is specially built for emotionally abused children. We must have alot of facilities like, water cooler, balls pool, swings, slides, treehouses, bridges and many more forest-like equipments. The equipments/facilities must also be low-lying so that infants on young children are able to reach it and will prevent them from falling from high point. Everything must be made of soft material in order to prevents accidents and it will allow the children to play more comfortably.
