The Government's free fruit for school children initiative provides an opportunity to ask geographical questions. Where does fruit come from? What weather does it like? How is it grown? Who picks it? How does it get to our school? (PoS 1a, 3e).
Compare the food the West eats with what is available in less economically developed countries. The Global Eye website has some good material www.globaleye.org.uk See also www.thehungersite.com (PoS 3f).
The walk to school week website www.walktoschool.org.uksite.htm has a wealth of ideas for primary health and lifestyle. These materials could be developed at KS3 into a "journey to school" investigation (PoS 1, 2b).
Ask pupils to compare the maps showing world income, calorie intake, diseases of obesity (heart disease) and malnutrition (kwashiorkor and marasmus) found in many atlases and websites, for instance www.who.inten KS4+
At GCSE and A-level, the impact of multinational companies on patterns of food consumption could be investigated. You will need to direct students to a small number of multinationals and guide them with a set of questions.
Where is the multinational's headquarters? Which countries have the greatest concentration of outlets? How are we encouraged to eat fast food? What are the advantages and disadvantages for people, the environment and the economy of this company's operations?
