Soybean Protein Levels
This video discusses the implications of protein levels in Midwestern soybeans decreasing over time.
Possible Guiding, Compelling and/or Anchoring Questions
- Why is the protein level in soybeans decreasing only in the United States?
- How are livestock impacted if they receive less protein in their soybeans?
- Compile and analyze data about the ratios of proteins, carbohydrates and fats in foods.
- Research and compare human nutritional needs to the needs of different livestock.
- Compare the chemical structures of different amino acids, carbohydrates and fats. Model how these compounds interact in the human or animal body.
- Model the energy and matter flows that occur in cellular respiration.
- Research the temperature-protein connection and discuss what it means that we can’t fully explain it yet.
