C1.2 evaluate, on the basis of research, the effectiveness of a common mechanical system in
addressing a social or environmental challenge (e.g., … high-efficiency heating and
cooling systems) [IP, PR, AI, C]
Sample questions: … How have integrated mechanical systems such as programmable
thermostats improved energy efficiency in homes?
D. Electricity and Magnetism
D1. Relating Science to Technology, Society, and the Environment
D1. analyse the development of selected electrical and electromagnetic technologies, and
evaluate their impact on society and the environment
D1.1 evaluate, on the basis of research, the impact on society and the environment of the
evolution of an electrical technology (e.g., electric cars or buses, electric appliances)
[IP, PR, AI, C]
Sample questions: What impact has the development and evolution of refrigeration
technologies had on society and the environment? Are trains powered by electricity an
improvement over trains powered by steam or diesel engines? Why or why not? What
impact does the use of electric buses, streetcars, and subway trains by the Toronto Transit
Commission have on local residents and the environment?
D1.2 assess the impact of an electromagnetic technology that is used for the benefit of society
or the environment (e.g., devices for diagnosing and treating diseases, technologies for
treating seeds to increase the rate of germination) [AI, C]
Sample questions: … What are some of the uses of electromagnetic technologies in
health care? What are the benefits of using electromagnetic sensors to detect metal
concentrations in brown-field developments? What are the advantages of maglev trains
over conventional transportation technologies?
E. Energy Transformations
E1. Relating Science to Technology, Society, and the Environment
E1. evaluate the impact on society and the environment of energy-transformation
technologies, and propose ways to improve the sustainability of one such technology
E1.1 analyse an energy-transformation technology (e.g., wind turbines, refrigerators,
telephones, steam engines, coal-fired electrical plants), and evaluate its impact on society
and the environment [AI, C]
Sample issue: Fax machines allow documents to be transmitted quickly and securely.
Most fax machines use ink cartridges, which can end up in landfill sites. By contrast,
thermal fax machines use heat resistors to convert electricity into usable heat. They then
apply this heat through a print head onto chemically treated paper to print a document.
Sample questions: What types of energy transformations take place in an air conditioner?
What impact does the widespread use of air conditioners have on society and the
environment? What types of energy transformations occur in incandescent and
fluorescent light bulbs? What impact does the difference in energy transformations in
these two types of bulbs have on the environment?
