Digestion

Author(s): Nancy Moreno, PhD, and Barbara Tharp, MS.

Digestion

This activity’s objectives are aligned with the National Science Education Standards, specifically those related to Science as Inquiry and Physical Science. In this activity, students will learn about digestion and proteins by observing the action of meat tenderizer on luncheon meat. Students will make predictions, make and record qualitative observations, and draw conclusions. 

Concepts

  • Food must be broken down into smaller units before it can be used by the body. 
  • Digestion is the process of breaking food down. 
  • Special chemicals in the body break food molecules into smaller units. 
  • Proteins—found in all meats, dairy products and vegetables (especially peas and beans)—are important for muscles and cell growth and repair. 

Student Worksheets

Student pages in the teacher’s guide are provided in English and in Spanish.
