1 I can describe the difference between metals.
Ferrous metals:

• Material steel: e.g. mild steel, carbon steel; wrought iron;

Non-ferrous metals:

• Material: e.g. aluminium; copper; lead;

Alloys:

• Ferrous alloys: e.g. nickel; cast iron; stainless steel;


• Non-ferrous alloys: e.g. brass; duralumin; solder.

Differences:

• Ferrous metals: e.g. contain iron; harder than non-ferrous material; rust;


• Non-ferrous metals: e.g. can be used to protect ferrous materials; protection against elements; corrosion;


• Alloys: e.g. mixture of ferrous and non-ferrous material; mixture according to industry needs.

2 I can describe the difference between woods.
Hard wood:

• Material: e.g. mahogany, oak, balsa wood, beech, walnut, cherry;

Soft wood:

• Material: e.g. pine, juniper.

Manufactured wood:

• Material: e.g. veneered, chipboard, plywood, block board, medium density fibreboard, oriented strand board.

Differences:

• Hard wood: loose leaves during the cold wood, broad leaves.


• Soft wood: evergreen trees, needle leaves, cheaper in price than hard wood, faster growth rate.


• Manufactured wood: can be manufactured according to industry needs, made from recycled natural wood, cheaper in price than natural wood, does not have live characteristics as natural wood.

3 I can describe the difference between polymers.
Thermosetting polymers:

• Material: e.g. polyurethane, polyesters, vulcanized rubber, Bakelite, epoxy resin, melamine, silicones.

Thermoplastic polymers:

• Material: e.g. polyethylene, polypropylene, polystyrene, acrylic, ABS, PET, PVC.

Differences:

• Thermosetting polymers: once set cannot be reset, during manufacturing these transform from liquid to solid, if exposed to heat these materials degrade rather than melt.


• Thermoplastic polymers: once heated to the ideal temperature can be reset, during manufacturing these transform from granules or powders to the actual object with the help of heat.

4 I can describe the function and types of smart material.
Types of smart materials: piezoelectric; shape memory alloys/polymers; magnetic shape memory; self-healing material.
Function: have one or more properties that can be significantly changed by certain conditions such as: stress, temperature, moisture, PH, electric or magnetic fields.
1 I can explain the properties of different materials needed for particular applications.
Properties: e.g. hardness, ductility, malleability, resistance to environmental degradation, strength, elasticity.
2 I can explain the different manufacturing processes of different materials.
Processes:

• Metal Processes: Annealing; hardening; galvanizing; electroplating.


• Wood Processes: seasoning; wood joints; bending; finishing.


• 
  Polymers:
   - Thermoplastic processes: vacuum forming, line bending, injection moulding, blow moulding, rotational forming,
   - Thermosetting processes: casting.
  

5 I can outline the different tests that can be carried out on materials.
Different tests: hardness; tensile; compression; shear; temperature; torque; impact; environmental degradation.
3 I can justify the test that needs to be conducted on given materials for a particular scenario.
1 I can carry out different tests in order to select an engineering material according to a given scenario.

6 I can identify the forms of supply available for engineering materials.
Forms of Supply:

• Metals: bar; sheet; pipe/rod; wire; castings; forgings; mouldings; extrusions; powders.


• Woods: planks; sheets; dowels; mouldings; beams.


• Polymers: film/sheets; pellets/ powders; extrusions; castings; pipe/rod; liquid.

4 I can justify the appropriate forms of supply of different materials for given engineering components.
COGNITIVE LEARNING

7 I can outline the functions of different measuring and marking out tools.

• Marking out tools: e.g. scriber, centre punch, chalk line, dividers/callipers, surface plate, trammel, blueing or paint, scribing block, mortise gauge.


• Measuring tools: e.g. ruler, measuring tape, protractor, gauges, veneer calliper, micrometre, engineer square, sliding bevel, combination sets.

8 I can outline the functions of different hand tools.
Hand tools: hammers/mallets; pincers; pliers; saws; screwdrivers; files; spanners and sockets; chisels; planer; taps and dies.
9 I can outline the functions of different power tools and machinery.
Power tools and machinery: drills; lathe; sanding machines; band saw; strip wire heater; hot air blowers; vacuum former; angle grinder; cross cut; jigsaw/scroll saw.
10 I can describe the appropriate use, maintenance and care of different tools.
Different tools: marking out tools; measuring tools; hand tools; power and machinery tools.
5 I can justify the choice of tools to be used to manufacture a particular engineering component.
