Do your students know the european energy label on domestic household products? The label is designed to provide consumers recognisable information on energy consumption, in order to allow sustainable consumer behaviour. The label initially classified products from A - most efficient energy class to G - the least efficient, but in 2010 classes were revised to adapt to technological improvement in terms of energy efficiency, introducing classes up to A+++ .
You can propose a guided discovery activity to your students in order to make them discover the energy label: visit a domestic household shop and ask them to choose the best product to buy: what considerations and strategies would them put into the field? Would they consider the label informations?
