Design and Technology - map 3
Deforestation
✮80% of the worlds forests have been destroyed since 1900
✮Consumers should really look to buy approved sources of timber where at least one tree is replanted
✮Slash and burn - trees are felled and then burned. The ash gives the soil nutrients for a short amount of time and crops are grown/ cattle graze
✮Once burned, the forest doesn't grow back
✮Wildlife looses its home which the forest once supported.
CO2
✮The amount of carbon emitted during a process is know as the carbon footprint.
✮Calculating carbon footprint is a way of estimating greenhouse gas emissions caused by process, person, event or organisation
The calculation considers
✮How you heat your home
✮The temperature of your thermostat is st to at home
✮How much you recycle
✮Whether your a meat eater, vegetarian or vegan
✮What type of transport you normally take
Poor working conditions
✮Paid very low wages
✮Work long hours in poor conditions
✮Lack of health and safety provision to protect from danger while at work.
Britain has the
HSE -Healthy and Safety Executive
✮Looks after the welfare of employees and enforces the Health and Safety at Work Act (1974)
Employers are obliged to provide a safe working environment
Landfill sites
✮Waste is buried which results in methane gas from rotting matter
✮The methane gas is collected and burned to generate heat or electricity
✮Unsorted waste directly into landfill is the least sustainable option
This happens on a large scale, causing environmental concerns about toxic chemicals and heavy metals leaching into the ground
Can find their way to water and resulting in potential poisoning of wildlife and the natural environment
Calculating manufacture cost
✮How much is going to used (materials)
✮Waste
✮ITS NOT IN THE FLIPPING BOOK
Audio and Visual recordings
Analysing how something is through the use of pictures or video/visual (for textiles)
Draping
How the garment lies/ fits on the model
✮Collecting data for a digital portfolio to write up lata
Mathematical Modelling
✮The maths involved with creating a product
✮Graphs and charts to communicate aspects of the design
in different situations
✮Application of mathematical principles, formulae, equations, and theories in the design process
✮Simulations and predictions
✮Evaluation and comparisons of performance
Primary Research
✮Interviews
✮Questionnaires
✮Focus Groups
✮Case Studies
✮Physical material testing
✮Product analysis
✮Observations of users and materials
✮Taking measurments
✮Information that you gather usually specific to the design chalenge
Secondary Research
✮Books, magazines, the internet
✮Official data (e.g, government statistics and company info
✮Media(news, radio, TV broadcast)
✮Exemplar work of other designers and/ or students
✮Sources and data from other people
Isometric drawings
✮Uses 30-degree angle and is more realistic
✮Dimensions can be done accurately
✮Good for geometric designs
✮Shows how parts fit and relate to each other
✮Complex shapes can be constructed or carved out
Tessellation
✮The nesting of similar shapes
✮Reduces waste and saves money/energy
Calculating material costs
✮Just go to calculating manufacture cost
