Animals Lesson 4 Tab 1

Students model and explain digestion, biosynthesis and cellular respiration using the Three Questions. They learn that the biomass of animals is mainly carbohydrates, fats, and proteins and relate the rearrangement of atoms in cellular respiration to energy release.

Guiding Question

How do animals use food to grow, move and function?

Activities in this Lesson

  • Activity 4.1: Molecular Models for Cows Moving and Functioning: Cellular Respiration (40 min)
  • Note: The steps that have students construct molecular models in this activity are optional if students did molecular modeling for cellular respiration in another unit and performed well on the pretest for items related to cellular respiration.

  • Activity 4.2: Explaining How Cows Move and Function: Cellular Respiration (40 min)
