In San Francisco, the cost of food varies by neighborhood. Some places don't have access to cheap healthy foods, some do. We want to find out the cost of food around the world. The basic hypothesis is that the cost of chicken varies geographically. It's much less in Africa then it is in San Francisco. But what proportion of the total income is this cost? 99¢ per pound for chicken legs at COSTCO is cheap to us. Is it as cheap as a 12¢ a pound chicken legs in Africa? 12 cents there might be a lot of money as a proportion of a total family income. Also, where do these chicken come from? Those sold in most San Francisco supermarkets are produced on mega farms, thus the cost per chicken is relatively low--we can afford to buy them. How about in other places? What if you live on a family farm and grow chickens? How many chickens can you reasonably grow for your family to consume? There are many interesting questions that could be asked AFTER the data is collected. Please visit http://www.CostofChicken.com to learn more and to get school worksheets.
