Lesson length: 2-4 hoursGrade level: 6-8Students learn about DNA and genetics through an exploration of corn genetics and soil types. The activities are grounded in engineering design thinking and relate to nutrient impacts of soil on the productive growing of corn with specific genetic characteristics. Students will consider genetic modification to address deficiencies as well as the consequences of these options.This material is based upon work supported by the National Science Foundation under Grant No. 1657263.
