Introducing Electrochemical Cells via Culminating Activity
Curriculum Expectations
- F1.1 assess, on the basis of research, the viability of using electrochemical technologies as alternative sources of energy (e.g., fuel cells for emergency power generation or as power sources in remote locations), and explain their potential impact on society and the environment [IP, PR, AI, C]
- F1.2 analyse health and safety issues involving electrochemistry (e.g., corrosion of metal pipes in drinking water systems) [AI, C]
CULMINATING TASK:
- Provide students with information which caters to their learning style. Ask students to choose one type of learning style and complete their assignment according to that learning style.
- POST THE TASK CHOICE BOARD

Please note the rubric attached to this
- Assess, on the basis of research, the viability of using electrochemical technologies as alternative sources of power and explain their potential impact on society and the environment OR analyse health and safety issues involving electrochemistry
- Hydrogen fuel cells use hydrogen as the fuel and oxygen as the oxidant, and produce water, rather than environmentally harmful greenhouse gases, as waste. Although some cars run on such fuels, what are the practical problems that must be resolved before this source of energy is used in the transportation sector?
- What is the capacity of a standard rechargeable battery before it has to be recharged? What impact has the use of rechargeable batteries in portable electronic devices had on society?
- What methods should be used to dispose of depleted batteries?
- Corrosion is a leading cause of structural degradation of bridges and roadways. Not only does rust weaken metal structures, but as it builds up it forces apart connecting parts of the structure, causing the structure to fail and risking public safety. However, methods used to prevent corrosion may also have negative effects on human health.
- Why do metal orthodontic braces no corrode?
- What are some of the toxic substances that can escape from electronic waste into the environment? What are the potential effects of these poisons on our health?
- What health and safety issues are associated with waste generated by electroplating companies?
