XENIA — The Greene County Fair this year is offering students participating in 4-H the opportunity to learn about what it takes to invest in and raise a commodity through the market in an interactive game.

The Commodity Carnival, brought to the fair by the CME Group and National 4-H Council, is offered 1-3 p.m. Tuesday, Aug. 1 through Thursday, Aug. 3 in the assembly building. Participants will learn how to recognize an agricultural commodity, such as coffee, vegetables, fruits and animal products, and how they apply to day-to-day living, grasp the investments it takes to raise a commodity and understand how risks apply to market sale prices.

The Commodity Carnival will specifically highlight a steer, taking participants step-by-step through the process of growing and selling the animal. Ideally participants will leave the carnival will a greater understanding of economics and the agricultural industry. The Commodity Carnival also provides an opportunity to highlight the impact 4-H has on its participants at local events.

The Commodity Carnival will take place at 120 state and county fairs across the Midwest. It was offered last year as the “Risk Ranch,” and highlighted a hog.
