National Geographic Education and The Center for Ecoliteracy have created BIG IDEAS: Linking Food, Culture, Health, and the Environment. The BIG IDEAS 3-5 Guide helps teachers to lead conversations with students about the linkages between the food we eat, the ways that culture shapes our food choices and behaviors, the relationship between food and our health, and the interconnections between our food systems and the environment.

To facilitate incorporating these themes, this publication identifies key “big ideas” that link food, culture, health, and the environment and demonstrates how they align with the following new academic standards:

• Common Core State Standards
• Next Generation Science Standards: Crosscutting Concepts
• College, Career, and Civic Life Standards for Social Studies (also known as C3)
• National Health Education Standards
• California Nutrition Competencies (from Nutrition Education Resource Guide for California Public Schools,
• Kindergarten Through Grade Twelve)

1. Biodiversity in Freshwater
