Year 1 (Non-model-based) 
Lesson Content and activities 
1. Exploring midwestern state agriculture  • Using interactive digital maps
 • Putting corn within geographic and economic context of regional agriculture 
2. The evolution of corn  • Putting corn in a historical context
 • Moving from teosinte to modern corn 
3. Corn growth and life cycle  • Comparing plant and animal life cycles 
4. Passing on traits: Focus on seeds  • Seed characteristics, seed structure and function, growth from seed to plant
 • Matching seeds to parent plants 
5. Variation in corn  • Investigation of corn types and traits
 • Characteristics are passed from generation to generation 
6. Influence of the environment  • Influence of environment on corn production and varieties 
Year 2 (Model-based) 
Lesson Content and activities Inclusion of modeling practices 
1. How do corn plant structures function to meet basic needs?  • Observation and identification of corn structures
 • Recognition of survival needs of plants 
 
2. Developing models of corn life cycle  • Identification of life cycle stages for plants and animals
 • Comparison of plant and animal life cycles 
Students develop a model that compares and contrasts life cycles of plants and animals 
3. What is inside a seed?  • Corn seed dissection and observation
 • Compare and contrast corn seed traits 
 
4. Why do offspring parents look like parent plants?  • Developing a model for corn inheritance
 • Recognition that seeds carry “coded instructions” for traits
 • Prediction of possible offspring based on parent plant traits 
Students construct, use, share, evaluate, and revise a model of inheritance in corn 
5. Are all corn plants the same?  • Analyze data and create graphs of different traits in a corn population Students create graphs to represent variation in traits 
6. How does the environment affect corn growth and production?  • Identify variation in corn traits according to the influence of environmental traits Students interact with a web-based game in which environmental factors affect corn production 
7. Where did modern corn come from?  • Exploration about traits of modern corn and old teosinte
 • Students compare and contrast traits of both organisms
