What are the 6 Rs
Reduce, Reuse, Recycle, Refuse, Rethink and Repair
What is a thermopolymer?
A form of polymer which can be moulded into a shape by heating, after it has set it can be remoulded by heating and reshaping it.
What is plastic memory?
This is when a thermopolymer attempts to return back to it’s original state when it is heated.
Give 3 examples of thermopolymers.
Acrylic, Polypropylene (PP), and ABS
What is a softwood?
Softwoods come from conifers, evergreen trees which keep their needles all year round.
What are some comparisons of softwoods and hardwoods?
Softwoods grow faster, the wood is usually lighter in colour and cheaper.
Give 3 examples of softwoods.
Pine, Cedar and Spruce
What is stainless steel?
A ferrous metal and an alloy made up of iron, carbon and chromium.
Stainless steel properties
Resistant to corrosion, strong and durable.
Stainless steel product examples
Kitchen utensils, cutlery, and appliances.
What is card?
Thin card is slightly thicker than paper, weighing 280-300 gsm. It is available in wide ranges of colour, sizes and finishes.
Properties of thin card.
Thin card is easy to fold, cut and print on making it ideal for things such as greeting cards, simple modelling applications and paperback book covers.
What is a stakeholder?
A stakeholder is a person, group or organisation with an interest in a product/system for example, parents or schools when designing products for children.
What is a woven fabric?
It is produced on manual or automatic looms. They are strong and breathable. They are made from fibres which are turned into yarn, which are turned into fabric, these fabrics are turned into woven fabrics.
What is primary research?
Primary research is the process of the maker of the product researching.
Primary data
Data that is found as a result of primary research.
Secondary research
The process of gathering data from existing collections and publishings. Using resources such as books, articles, reports and websites. It is often cheaper than collecting primary data.
Systems thinking
The understanding of a product or component is part of a larger system of other products and systems in the iterative design process, consideration of the role of all components and subsystems of the product or system, including user experience and the marketing of the object being designed, ensures all aspects of the product are given the required attention to detail.
Aesthetically pleasing definition.
Something that is pleasing to the senses.
Aesthetics definition.
Factors concerned with the appreciation of beauty. This can include how something looks, sounds, feels, tastes and smells.
Red
Aggressive, passion, strong, danger, socialism and heat.
Blue
Comfort, loyalty, sea, sky, peace, tranquility, conservatism and cold.
Yellow
Caution, spring and brightness, joy, cowardice and sunlight.
Green
Money, health, jealousy, greed, food and nature.
Brown
Nature, aged and eccentric
Orange
Warmth, excitement, energy, religion, fire and gaudiness (Mr Birling)
Pink
Soft, healthy, childlike, feminine, gratitude and sympathy.
Purple
Royalty, sophistication, religion, creativity and wisdom.
Black
Dramatic, classy, serious, modern, evil and mourning.
Grey
Business, cold, distinctive, humility and neutrality.
White
Clean, pure, simple, innocent, elegant and peace.
Proportion
The relative size and scale of the various elements in a design.
Symmetry
When elements are arranged in the same way on both sides of an axis or when rotated around a point
Asymmetry
The absence of symmetry of any kind.
Golden ratio
A common, mathematical ratio found in nature, it can be used to create, pleasing, natural looking compositions in your design work; also known as the golden mean, the golden section or by the Greek letter Phi. 1:1.618
What is an input?
The type of motion put into a mechanism.
Output
The type of motion a mechanism produces.
Arm length
The distance between the force being exerted and the fulcrum.
Effort
Input of the force
Fulcrum
The pivot around which a lever turns.
Lever
A ridged bar that turns around a fulcrum.
Load
The output force.
Microcontroller
A programmable electric component that adds functionality to a product. E.G. Micro:Bit
Upcycling
Recycling into a higher quality product.
Rethink
How can it do the job better? Is there another way of doing it altogether? Is it energy efficient? Has it been designed for disassmbly?
Reuse
Which parts can it use again? How easy is it to take apart? Has it another valuable use without recycling or discarding it?
Recycling
The action or process of converting waste into reusable material.
Repair
Which parts are likely to fail or wear? How easy is it to replace parts?
Reduce
Which parts are not needed? Do we need as much material? Can we simplify the product?
Refuse
Is it really necessary? Is it going to last? Is it fairtrade? Is it too unfashionable to be trendy and too costly to be stylish? Is it ethically wrong? Is it made from material that is scarce?
Renewable energy
Sources can be replenished naturally in a short period of time.
Hydroelectric
Dam is used to trap water, the water released turns turbines, turbines turn generators, electricity is distributed.
Wind
Blades are designed to catch wind. Blades turn turbines using gears, turbines turn generators, electricity is distributed.
Solar photovoltaic
Photovoltaic cells convert light into electricity.
Tidal barrages
Barrage built across river estuary, turbines turn as tidfe enters (and when tide leaves), turbines turn generators, electricity is distributed.
Wave
Motion of waves forces air up cylinder, turns turbines, turbines turn generators, electricity is distributed
Geothermal
Cold water is pumped underground through heated rocks, steam turns turbines, turbines turns generators, electricity is distributed
Biomass
Fuel (wood, sugarcane, etc.) is burnt to generate heat, which heats water to generate steam, steam turns turbines, turbines, turbines turn generators, electricity is distributed.
