Friday, March 5, 2010
Use the following questions as your guide
1. What are the different types of materials in the market? Classify the materials into wood, metal, plastics and others.
2. What are the properties of the different materials?
3. How do the different materials come about? What are their compositions?
4. Give examples of the use of each material.
5. What is sustainability?
7. What does it mean when we say that a product is sustainable? Give an example of a sustainable product and explain why the product is sustainably.
8. What does it mean by a sustainable environment? Give an example of a sustainable environment.

Different Types of Wood (Azeem):
-Agba
-Afziela
-Afara
-Alder
-Ash
Different Types of Leather (Bernard):
Properties of the Materials:
Plastic:
-Acrylic: Best known as a glass substitute, typically under the trade names Perspex, Lucite and Plexiglas.
-Cellophane : A Du Pont trade name for film made from regenerated wood pulp (cellulose).
-Cellulose : The fibrous matter in all plant cells, with a long chain molecular structure. The most common sources used for making plastics are cotton fibres and wood pulp
-Cellulose acetate: A tough thermplastic made from cellulose in the form of cotton linters, treated with acetic acid and acetic anhydride. Used for many domestic mouldings such as spectacle frames, toothbrush handles, and as transparent packaging film.
-Elastomer: A synthetic plastic with the flexible properties of rubber.
-Epoxy resin: A very tough thermosetting resin used as a coating, or reinforced to make mouldings or laminates.

Metal:
silver, platinum and gold: all are precious metals and are highly maleable and ductile. Most pure metals are soft too
Copper. bronze and nickel: They are not really precious and are cheap.

Wood:
All of the above have wooden origins
Leather:
How It Came About?
Plastic:
-Acrylic: a hard thermoplastic made from acrylic acid or a derivative of acrylic acid.
-Amino plastics: Plastics made from ammonia based compounds
-Cellophane : A Du Pont trade name for film made from regenerated wood pulp (cellulose).
-Cellulose : The fibrous matter in all plant cells, with a long chain molecular structure.
-Cellulose acetate: A tough thermplastic made from cellulose in the form of cotton linters, treated with acetic acid and acetic anhydride.
-Elastomer: A synthetic plastic with the flexible properties of rubber.
-Epoxy resin: A very tough thermosetting resin used as a coating, or reinforced to make mouldings or laminates.

Metal:
Platinum: chemical symbol: Pt, atomic number: 78, atomic mass: 195.1
Silver: chemical symbol: Ag, atomic number: 47, atomic mass: 107.9
Gold: chemical symbol: Au, atomic number: 79, atomic mass: 197.0
Copper: chemical symbol: Cu, is either pure or made from brass and bronze.
Bronze: has no chemical smybol because it is not an element, made of various alloys of copper and tin.
Some of the metals came from the ground and was naturally made. Some of them were man-made and were made from a mixture of other natural materials.

Leather:
What Is ‘Sustainability’?
Sustainability is the capacity to endure, to maintain at a certain rate.
7. What does it mean when we say that a product is sustainable? Give an example of a sustainable product and explain why the product is sustainably.
It means that the product is able to wistand its own weight and the weight of the contents on it. An example would be a chair. The chair is able to wistand its own weight and the weight of the person that is seating on it. The chair does not collapse when someone seats on it.
8. What does it mean by a sustainable environment? Give an example of a sustainable environment.
An environment that has the daily necessities that we can live in. An example would be living on arable land. We are able to plant crops on the land. The plants would photosynthesize, we get oxygen.

Environment - Melting Ice Caps
What Is Happening Now In The Artics
-temperatures have been rising in the arctic
-thickness of the ice sheet has decreased
-Springs are coming earlier, and fall is arriving later
-Surface temperatures are increasing at a rate of 2 degrees per decade
-water absorbs heat and thus increases the heat
source: http://www.awitness.org/journal/melt_ice_cap_glacier.html
Cause
human activities (emission of greenhouse gases, deforestation)
Emission Of Greenhouse Gases
-transportation needs, burning of fossil fuels
Burning of fossil fuels
-like petroleum, oil, coal, natural gases
Solutions
-find greener way to make electricity and use energy conserving items like energy bulbs. (solar panels, wind mills)
-use items that do not produce air pollution (cars that run on electricity)

S.C.A.M.P.E.R
S: Subsitute Think about substituting part of your product/process for something else. By looking for something to substitute you can often come up with new ideas.
C: Combine Think about combining two or more parts of your probortunity to achieve a different product/process or to enhance synergy.
A: Adapt Think about which parts of the product/process could be adapted to remove the probortunity or think how you could change the nature of the product/process.
M: Modify/ Distort Think about changing part or all of the current situation, or to distort it in an unusual way. By forcing yourself to come up with new ways of working, you are often prompted into an alternative product/process.
P: Put to Other Purposes Think of how you might be able to put your current solution/ product/process to other purposes, or think of what you could reuse from somewhere else in order to solve your own probortunity. You might think of another way of solving your own probortunity or finding another market for your product.
E: Eliminate Think of what might happen if you eliminated various parts of the product/process/probortunity and consider what you might do in that situation. This often leads you to consider different ways of tackling the probortunity.
R: Rearrange/ Reverse Think of what you would do if part of your probortunity/product/process worked in reverse or done in a different order. What would you do if you had to do it in reverse? You can use this to see your probortunity from different angles and come up with new ideas.
When to use S.C.A.M.P.E.R?
-When you are trying to create a new product and you chould ask yourself whether the product is good or not and if it will do well in the market
-When you want to get an inspiration.
-When you are doing projects or writing compositions.
For the above sketch:
S: Instead or holding the water bottle in hand, the water bottle is attached to the cycling helmet.
C: The invention is a combine of a water bottle and cycling helmet.
A: The designs and patterns on the helmet is adapted.
M: The size of the water bottle is minimized.
P: The cycling helmet, with the holder, can use to hold water bottle.
E: Eliminate the work of screwing open the water bottle.
R: The cycling helmet is used in two ways, one is to protect the head from injuries and to hold the water bottle.
