2. THE ORIGINS OF MATERIALSORGANIC ORIGIN• Materials that come from plants or animals.• Ex: Wood, linen, cotton, wool, cork, leather, bees wax…
SYNTHETIC ORIGIN• Materials that come from oil.• Ex: Gasoil, petrol, asphalt, paraffin, plastic, PVC, polyester, lycra,,,
MINERAL ORIGIN• Materials that come from rocks.• Ex: Marble, glass, granite, slate, clay, porcelain, chalk, talc, cement, gravel…
METALLIC ORIGIN• Materials that come from metallic minerals.• Ex: Copper, aluminium, steel, iron, bronze, gold, silver, titanium…

3. RENEWABLE vs. NON-RENEWABLE
Materials that come from a resource that is regenerated fastly.
As we waste the resource, we (or nature) can produce more.
Materials that come from a resource that isn’t regenerated fastly.
We waste more resources than we (or nature) can replace.

REVIEW ACTIVITY:THE LIST1- INDIVIDUAL TASK TIME: 3 minCopy this chart and write as many materials as you can think of
in each of the columns:
When the time’s up, draw a line under your last materials.
2- COOPERATIVE TASK TIME: 2 minHave a look at your partners’ lists and check if they wrote
anything you didn’t. Add their ideas under your line.

ACTIVATION ACTIVITY1- INDIVIDUAL TASK HOMEWORKAnswer to the 4 questions we just saw in the presentation:
What if…?
For example: What if cables were made of paper?If cables were made of paper, paper would burn with the electricity and the cables would not work.
What if chairs were made of ice?If chairs were made of ice, they would be very cold and nobody would sit on them.
