This activity gives students a way to look at how organisms are connected to ecosystems through the cycling of matter and the flow of energy. By the end of the activity, students will be able to make distinctions between how matter and energy are used and transferred and will be encouraged to apply this important crosscutting concept to the world around them.

First, students observe an animal, then they reflect on how it uses matter from food to build body structures and energy from food to do things. Students look at food as “packages” of matter and energy that animals (and plants) consume. They also think about wastes, such as poo, pee, sweat, heat, and carbon dioxide. This is a focused activity best used as part of an extended matter and energy-themed experience, and it works best after students have had time to explore, check out organisms in other ways, and be physically active.

This course explores connections between what we eat and who we are through cross-cultural study of how personal and collective identities, social relations, and economic inequalities are formed and maintained via practices of food production, preparation, and consumption. Discussions are organized around critical discussion of what makes "good" food good (tasty, healthy, authentic, ethical, etc.), and draw on anthropological studies as well as recent writing and films on the politics of food and agriculture. A primary goal of the course is to provide students with conceptual tools to understand and evaluate food systems at local and global levels. Instruction and practice in written and oral communication is provided.

This course explores the values (aesthetic, moral, cultural, religious, prudential, political) expressed in the choices of food people eat. Analyzes the decisions individuals make about what to eat, how society should manage food production and consumption collectively, and how reflection on food choices might help resolve conflicts between different values.

El desperdicio de comida es uno de los principales contribuyentes a los gases de efecto invernadero. Los alimentos desperdiciados y los recursos para producirlos son responsables de aproximadamente el 8% de las emisiones mundiales de gases de efecto invernadero. En este caso, los estudiantes aprenden sobre los recursos necesarios para producir alimentos a través del ciclo del carbono y descubren cómo el desperdicio de alimentos contribuye al cambio climático. También aprenderán la cadena de transporte de la granja a la mesa y cómo llevar a cabo una evaluación de desperdicio de comida. Finalmente, los estudiantes investigarán soluciones al problema del desperdicio de comida y, como proyecto final, presentarán una solución que han investigado a fondo que puede ser aplicable a su comunidad. Para los maestros de CTE, este caso proporciona el conocimiento básico necesario para desarrollar una comprensión profunda de POR QUÉ reducir el desperdicio de comida es una solución importante para el cambio climático. Hay varias extensiones potenciales que los maestros de ciencias del consumo familiar pueden utilizar, así como los maestros de Agricultura e incluso los maestros de Negocios. Hay una lista parcial al final de las progresiones de aprendizaje.
