Can we predict the yield of a crop and forecast food production?
Use hula hoops and math to predict how many bushels of soybeans are growing in a particular field. This fun activity was tested with 500 6th graders from Newark City Schools at the Devine Farms in Hebron, Ohio and is an adaptation of an actual yield prediction method used by extension agents from Purdue University.
Take a small sample in a field by counting the number of plants inside a hula hoop. The worksheet guides students through a step-by-step process to calculate the potential yield of an acre of soybean plants.
Soybean growers have important decisions to make early in the growing process. A yield calculation can determine the outcome. Should the farmer replant a field based on low expected returns? A replant is, in effect, a late planting and that will decrease potential yield. Growers must consider and evaluate the cost of seed, fuel, machinery, pesticides, labor, and other expenses.
