Ruminant Digestive Components

Task Description

Standards

In this activity, students will

  • name and explain the characteristics of each component of the ruminant stomach;
  • create an anatomically correct model of a ruminant digestive system using disposed household items, such as a milk jug, bread wrapper, cardboard cylinder inside a roll of paper towels, egg carton, etc.;
  • present or film themselves explaining the path and digestive process as feedstuff travels through the ruminant model.

Agriscience

14) Classify the types of digestive systems in domestic animals and compare and contrast their anatomical and physiological differences. Synthesize research on animal nutrition (using academic journals or publications from Tennessee Extension Service) to produce an informative narrative, including defining and applying nutrition specific terminology, to examine the stages of digestion and associated processes.

 Content Understandings

Extending Understandings

Upon successful completion of these tasks, students will demonstrate the ability to:

  • identify the parts of the ruminant digestive system;
  • explain the specific characteristics of the different parts of the ruminant digestive system.

To move students towards deeper understanding, they should be given opportunities to:

  • compare and contrast the parts of a ruminant digestive system to a non-ruminant digestive system;
  • teach other students the physiological differences between the two digestive systems.

Support Strategies

If students are struggling to access this task, additional supports and strategies could be employed as students are engaging with the task.

  1. Do ruminants have bugs in their stomach? If so, what type and why?
  2. What type of enzymes are added to the feedstuff within each compartment of the ruminant stomach?

Agriscience Ruminant Digestive Components

Directions: After completion of the ruminant digestive system unit, create an anatomically correct model of a ruminant digestives system using disposed household items, such as a milk jug, bread wrapper, cardboard cylinder inside a roll of paper towels, an egg carton, etc. Label each component and be ready to either present online or film yourself identifying and explaining the characteristics of each component as feedstuff travels through the model ruminant digestive system.

 

Expectations for the presentation or film: Your teacher will provide you directions and expectations to either present your model in an online live presentation or video format.   Practice your presentation.
