Lección 2.3: Analizando

Descripción

Cuando se trata de oportunidades para combatir el cambio climático, ¿porqué no empezar en el hogar? Los hogares no solamente tienden a ser responsables de gran parte de la emisión de GGI, también es el lugar donde la mayoría de la gente suele pasar gran parte de su tiempo. Con esta lección, los alumnos completarán una auditoría medioambiental y un análisis del ciclo de vida de un producto o servicio de hogar para determinar cómo reducir su huella ecológica.

Tarea

En la semana antes de esta actividad, pide a los alumnos prestar atención a sus hábitos de consumo en casa. Pedir que se fijen en lo siguiente:

Uso de energía
Uso de agua
Productos de consumo en el hogar (limpiadores, perfumería)
Consumo de alimentos
Eliminación de residuos

...through the Writing section of the classroom. When the week is over, watch the Story of Stuff video and reflect on the lifecycle of the products described in the video. Post a reflection on the video in a blog post. Next, work individually or in groups to brainstorm activities and consumption patterns related to one of the following rooms:

Kitchen
Living room
Bedroom
Bathroom
Garage

Select one household item or function related to the room you chose as the subject of a "lifecycle assessment." A lifecycle assessment is the investigation and evaluation of the environmental impacts of a given product or service, through looking at the material and energy flows involved in the creation and use of the product or service. Also known as cradle-to-grave analysis because this method takes into consideration all inputs and outputs throughout the lifecycle of a product or service from the extraction of resources (cradle), to production, distribution, consumption, and disposal (grave). Consider the flows of natural resources, energy, materials and wastes involved in the production, distribution, consumption, and disposal of the good or service in question. Use exploratree to create a flow diagram to illustrate the inputs and outputs, using different colours for each type of material flow. Share your lifecycle assessment experience through a blog post. Be sure to answer the following questions:

Where does this item/service originate?
What resources and materials were used in creating it?
How is it used?
Where does it go after it is used?
What are the impacts of the product/service beyond the household?
