Δράση
step 1
Ask students to write down all the products that made up their meals yesterday (breakfast, lunch, dinner, snacks) or describe the ingredients of their favourite dish (template on A4 paper - list of ingredients + mileage).
step 2
Discuss the origin and the route of transport of common foods consumed (potatoes, tomatoes, bananas, avocados, cocoa, soya, rice, meat, fish, etc.).
step 3
Students work in groups of 3:
- They seek information on the origin of the products on their lists. Students use Google Earth to identify the transport route from the country of origin to this country.
- They calculate the number of kilometres each product has travelled. Each student sums up the number of kilometres for products on his/her list. For products originating in the same country enter 0.
- Students will choose five products which have taken the longest route.
- They mark the route of the products on the map by sticking string in appropriate colours (e.g. green for vegetables, blue for fruit, yellow for seeds and cereals, red for meat/fish, white for dairy products) from the place of production to their country.
step 4
Students then rank their cards in the order from the lowest to the highest total value of the list of kilometres from the product lists.
step 5
Each group presents the results of their work.
step 6
Working in pairs, students will list all known effects of buying products from distant countries on local and global ecosystems.
step 7
The pairs will merge into groups of 4, then choose the three most important effects and illustrate these.
step 8
Groups place the results of their work on a table shared by all groups to be discussed as a class.
