Students learn and use a scientific model to explain digestion and biosynthesis using the Three Questions.
Guiding Question
How do animals use food to grow?
Activities in this Lesson
- Activity 5.1: Tracing the Processes of Cows Growing: Digestion and Biosynthesis (40 min)
-
Activity 5.2: Molecular Models for Cows Growing: Digestion and Biosynthesis (40 min) - Activity 5.3: Explaining How Cows Grow: Digestion (40 min)
- Activity 5.4: Explaining How Cows Grow: Biosynthesis (40 min)
Note: The molecular modeling part of Activity 5.2 is exactly the same as the molecular modeling for biosynthesis in the Plants and Decomposers units. Additionally, it is a 2-turtle activity which means it involves a higher level of complexity. Consider skipping the activity if you have already taught it in another unit or if it is too advanced for your class.
