SPECIFIC EXPECTATIONS
By the end of this course, students will:
B1.1 analyse the design and uses of a transportation technology (e.g., snowmobiles, automobiles, motorized personal water craft), and evaluate its social and environmental impact, including the impact on risk behaviour and accident rates [AI, C]
Sample issue: All-terrain vehicles (ATVs), designed to be driven off-road, are used in occupations requiring access to remote areas and for recreational purposes. However, ATVs can lack stability on uneven surfaces, which can result in serious accidents, particularly for inexperienced drivers. The vehicles can also cause damage when they are driven in environ- mentally sensitive areas.
Sample questions: What design aspects of the snowmobile make it particularly useful for travel over ice or snow? What impact does the altering of a vehicle’s centre of gravity have on the func- tioning of the vehicle? Why is it important to take training courses before operating a motorized vehicle? Why are there special licences and train- ing for different kinds of motor vehicles?
B1.2 analyse how technologies are used to track the motion of objects, and outline various kinds of scientific knowledge gained through the use of such technologies (e.g., data on animal popu- lations and migrations, on changes in ocean currents related to global warming, on the be- haviour of celestial objects) [AI, C]
Sample issue: In order to bill drivers for road use, a toll highway in southern Ontario uses motion cameras and transponders to track where vehicles enter and exit the highway. The information provided can also be used to ana- lyse traffic flow and to determine when existing roads are unable to handle the volume of traffic.
Sample questions: How are motion-related tech- nologies used to monitor wildlife populations? What type of information do these technologies provide, and how is it used? How are satellites used to track weather systems? What are the uses of the information gathered?
By the end of this course, students will:
B2.1 use appropriate terminology related to motion, including, but not limited to: distance, displace- ment, position, speed, acceleration, instantaneous, force, and net force [C]
B2.2 plan and conduct investigations to measure distance and speed for objects moving in one dimension in uniform motion [IP, PR]
B2.3 plan and conduct investigations to measure constant acceleration for objects moving in one dimension [IP, PR]
B2.4 draw distance–time graphs, and use the graphs to calculate average speed and instan- taneous speed of objects moving in one dimension [PR, AI, C]
