- Corn rootworms cause an estimated $1 billion dollars of damage to corn each year, and scientists are trying to find ways to protect corn against the pest. At MU, scientists are breeding a new form of corn that is resistant to the corn rootworm. In order to test if their modified corn performs better, they introduce the corn rootworm to mutant and non-mutant forms.
- This Data Nugget engages students in solving a real-life problem. Students will investigate the differences in growth of corn rootworms grown on the roots of mutant and non-mutant corn. Based on their analysis of the data, they will make inferences on the resistance of mutant and non-mutant strains to corn rootworm infestation and make recommendations to farmers on use of the mutant vs. non-mutant strains.
- Plan to engage students with this lesson for approximately 1 hour.
