This Triple Crossed activity, from the Centre for Science Education and supported by the Astra Zeneca Teaching Trust, looks at four fictional food diaries, each lacking in some nutrient. Students are asked to identify what is missing, provide details of what they ate the previous day and analyse their own diet. With this in mind they are then asked to investigate food miles in both the Roman period and the present to consider the differences and the impact transporting food has on the environment.
The resource is accompanied by a set of teachers' notes. There are also teachers' tools consisting of four 'substitute' food diaries for the session two starter activity.
