Grade 11 - Energy, Power, and Transportation(Problem Solving)

PRESCRIBED LEARNING OUTCOMES

• measure the efficiency and performance of systems that use contemporary energy sources
• perform test procedures on computer-equipped energy systems and communicate results
• diagnose and repair problems in electrical and mechanical devices and systems
• apply teamwork skills to solve problems involving mechanical systems and subsystems

SUGGESTED INSTRUCTIONAL STRATEGIES

• Ask students to gather and use information from a variety of sources (e.g., the Internet, CD-ROMs, technical journals) to solve a technological problem (e.g., describe an optimal gearing for a vehicle to maximize fuel efficiency; examine fossil-fuel alternatives to power vehicles). Have them synthesize the information they gather, generate alternatives, assess the merits of various solutions based on the literature, and create action plans.
• Have students work in teams to develop checklists to assess and diagnose the efficiency of an engine that uses computer-equipped energy systems (e.g., computerized fuel-injection systems). Ask them to include criteria for fuel efficiency, acceleration, speed, emissions, and ignition system operations. Using information from a variety of sources (e.g., repair manuals, CD-ROMs, technical journals), challenge students to calibrate and optimize (tune up) the engine based on their assessments, using the checklists as a guide. Have them use charts to record their findings.

  Pre-Modification Data		Modifications	Post Modification Data
  Fuel Efficiency	L/100 km	Carburetor Adjustment	L/100 km
  Acceleration	0-30 km/h in 9.2s.	Tune-Up	0-30 km/h in 8.1s
  Top-Speed	65 km/h	Tune-Up	80 km/h
  Emissions	0.25 ppm	Clean Air Filter	0.0075 ppm
  Ignition System Plugs	Oily	Timing	Good Burn

  Check to see that they use correct terminology when they refer to parts and procedures and communicate diagnostic data.

SUGGESTED ASSESSMENT STRATEGIES

• Have students form teams of consultants to investigate and report on the efficiency of a variety of home heating systems, using information sources such as the BC Hydro Power Smart program. Note the extent to which students are able to:
  • identify and describe various methods of measuring efficiency
  • use correct terminology when describing heat transfer
  • support their conclusions with factual data
• When students tune up a modern computer-controlled engine, watch for evidence that they are able to:
  • apply valid test procedures to verify that the computer system is performing properly
  • interpret technical manuals
  • use correct terminology to communicate faults, ideas, and procedures
• Conference with students individually about their contributions to their design teams. Pose questions such as:
  • What were your specific contributions to the group?
  • As your group encountered problems, what strategies did you use to help?
  • What will you do differently next time?
  • What specific things did you do to initiate, develop, or sustain interactions in the group?
  • How did you build on the ideas of others?
