Life Science: Eating and Exercise (MG)

by Texas Instruments - Simulation Lesson


  • Students will learn how food and exercise work together to determine weight loss, gain, or maintenance over time and that a balance is needed.
  • Students will discover how their daily intake of calories from proteins, carbohydrates, and fats compares to the recommended daily allowance for middle school age.
  • Students will learn that daily exercise will raise their basic metabolic rate (BMR), calories burned while at rest.

About the Lesson

Adapted from a PhETTM simulation, this lesson involves students using TI-Nspire technology to simulate, observe, and manipulate the factors that affect weight over time.

As a result, students will:

  • Reinforce understanding of the interaction between food intake and exercise on weight gain and how they can utilize tools to help them make good choices.
  • Understand that maintaining an optimal weight is important to maintaining good health and that a balance is needed between eating and exercise.
  • Recognize that they should follow expert recommendations for food and exercise types and amounts.
