Imagine a school teaching Chicago children from kindergarten through 12th grade on a seven-acre campus — three of those acres devoted to urban agriculture — designed by famed architect Jeanne Gang’s Studio Gang. Imagine this school incorporating local citizenship, sustainability, Good Food, social justice and other values into its curriculum… serving organic, locally sourced, made-from-scratch food in its cafeteria… and producing more energy than it uses. Then imagine this school is not in an upscale Chicago neighborhood or tony suburb, but rather on the industrial, mostly Hispanic, mostly low-income Southwest Side. That is the vision for the expansion of the Academy for Global Citizenship — for which the charter school’s foundation will raise money at its 5th Annual Chefs Playground on June 9 at the Art Institute of Chicago.
