This lesson contains everything that your students need to know about how to perform a selective Life Cycle Assessments as per the AQA specifications for Chemistry (8462), Combined Science Triology (8464) and Combined Science Synergy (8465). The lesson takes your students through how to evaluate the environmental impact of each of the different stages of a product’s life cycle as well as how to critique the usefullness of any given LCA. The lesson resources include the teaching presentation, information sheets and past AQA exam questions.
