Students calculate the energy cost of their daily electrical use. Provide starter examples: 'LED light 10W × 8 hours = 80 Wh = 0.08 kWh', 'Computer 200W × 4 hours = 0.8 kWh', 'Fridge 100W × 24 hours = 2.4 kWh'. Students add sticky notes for their own devices: TV, phone charger, microwave, hair dryer
