Grade 12, Workplace Preparation
A4. Mathematics,Science,and Technological Literacy
A3. Material Conversion
THE ONTARIO CURRICULUM, GRADES 11 AND 12 | Technological Education
A2.5 demonstrate a working knowledge of ways in which technological concepts (e.g., aesthetics, control, environmental sustainability/stewardship, ergonomics, fabrication, function, innovation, material, mechanism, power and energy, structure, safety, systems) are important considerations in the design process (see pp. 7–8).
By the end of this course, students will:
A3.1 apply appropriately a variety of processes used to join materials (e.g., gas tungsten arc welding [GTAW], gas metal arc welding [GMAW], shielded metal arc welding [SMAW], bonding, fastening);
A3.2 demonstrate a working knowledge of the processes used to cut or separate materials (e.g., using a CNC machine, oxy-acetylene cutting torch, lathe, mill);
A3.3 demonstrate correct processes for forming materials, using various tools and equipment (e.g., brake press; English wheel; forging, casting, and moulding tools and equipment);
A3.4 demonstrate correct processes for converting the structure of a material using a variety of metallurgical processes (e.g., heat treating, annealing, shrinking, tempering / work hardening).
By the end of this course, students will:
A4.1 demonstrate appropriate use of various mathematical formulas (e.g., related to trigonom- etry, sine rule, taper calculation, bend allowances) and applications (e.g., tap drill sizing, calculating machine speed and feed rate, indexing) that are commonly used in manufacturing;
A4.2 use appropriate mathematical solutions to solve manufacturing problems (e.g., use algebra- ic equations; calculate perimeters, volumes, areas), consulting appropriate resources (e.g., tables, charts);
A4.3 apply mathematical concepts and scientific principles (e.g., concept: torque; principle: Bernoulli’s principle) related to power trans- mission and mechanical mechanisms (e.g., hydraulics, pneumatics, gears, pulleys, levers, couplings);
A4.4 demonstrate a working knowledge of physi- cal and mechanical properties of materials
(e.g., physical: appearance, density, surface tex- ture; mechanical: hardness, malleability, ductility, elasticity) that affect the suitability of materials for use in manufacturing;
A4.5 use appropriate manufacturing terminology to communicate information related to the fab- rication of a project;
A4.6 demonstrate effective use of research skills (e.g., obtaining and evaluating information from technical documents and manufacturing resources) and technological literacy and communication skills (e.g., log note writing, record keeping, data recording, memo writing, schedule creation) to plan and document work on a manufacturing project.
