One Small Bite for Man

Published on 09/09/2016

Activity Overview

One Small Bite for Man is a project-based STEM activity that explores cellular respiration and will engage your students in the engineering design process while using TI-Nspire™ CX with the TI-Innovator™ Hub.


Students will research science topics including:

  • Energy and material flow in cellular respiration.
  • Animal cell organelles.
  • The effects of Body Mass Index and activity level have on energy usage (calories consumed).


  • Mitochondria
  • Cellular Respiration
  • Calories
  • Body Mass Index (BMI)

About the Lesson

Your students are asked to play the role of a horticultural engineer on the International Space Station (ISS) who has been researching food production for extended space exploration missions. Students will design and build a model of an astronaut that consumes energy according to the BMI and activity level assigned in simulation of a space work environment

As a result, students will:

  • Use their model to investigate how Body Mass Index (BMI) and activity affect a person's daily food requirements.
  • Will use mathematical processes of:
    • Area of a rectangle
    • Slope of a line
    • Interpreting graphs
    • Proportional reasoning
