Material World Objectives (Content)

1.2. Define the term Synthetic.3. Identify that a plastic is a material that can be molded.4. Define the term polymer and identify that plastics are examples of polymers that originate from

petrochemicals.5. Define the term monomer and identify that polymers consist of monomers.6. Define polymerization as a chemical reaction which joins monomers to form a polymer.7. Identify poly-ethene as common plastic used to make common material such as cling wrap and

plastic bottles.

8. Identify a catalyst as a substance that speeds up a reaction but is not changed by the reaction.

9. Distinguish between thermoplastic polymers and thermosetting polymers.10. Describe and explain the properties of thermoplastics and thermosetting plastics and relate

their uses to their properties.11. Identify that, until the 1940s, all clothing was made from natural fibers giving examples of such

fibers.

12. Identify the most commonly used synthetic fibers as nylon and polyester.13. Identify rayon as a regenerated fiber from cellulose.14. Identify ceramics as substances made from clays.15. Describe the properties of ceramics.16. Define a colloid as a mixture in which solute particles are too small to settle or to be removed

through filtration.17. Identify examples of colloids (including smoke, mist).18. Identify an emulsion as a colloid formed from two liquids.19. Identify cosmetics as consisting of chemical substances.20. Identify that skin creams consist of emulsions of water and oils or waxes.21. Identify fragrant compounds as consisting of essential oils extracted from plants.22. Identify plaque as a film of saliva, bacteria and food particles.23. Identify that chemistry is divided into organic and inorganic chemistry and that organic

chemistry involves the chemistry of carbon compounds.24. Identify that carbon has four valence electrons in its outer shell, so that each carbon atom is

surrounded by four single covalent bonds.25. Explain the meaning of saturated and unsaturated in relation to carbon compounds.26. Describe the system used for the naming of hydrocarbons.27. Define the functional group and homologous series. 28. Identify examples of hydrocarbons, alkyl halides, alcohols, alkanoic acids and esters.29. Describe the properties of metals.30. Define an alloy as a mixture of metals.31. Identify three types of steel and their properties.32. Discuss reason for recycling material including plastics.
