Lesson summary
Students will explore the concept of value and energy efficiency in household appliances. They will use scientific knowledge to make informed choices when purchasing appliances for a new house, considering factors such as initial cost, long-term running costs, energy efficiency, and environmental impact. The lesson engages students in real-world decision-making and encourages them to think critically about the consequences of their choices in terms of energy conservation and environmental sustainability.
Learning intentions:
Students will...
- investigate the meaning of energy star ratings given to appliances and explore what affects the efficiency of these appliances
- evaluate a range of appliances and recommend choices based on efficiency, environmental impact and cost.
Success criteria:
Students can...
- summarise the Energy star ratings given to appliances
- describe what affects the energy efficiency of household appliances
- recommend appliances to purchase based on efficiency, environmental impact and cost.
