Mathematics for a Sustainable Future – Reducing Food Waste

Introduction

Welcome, young mathematicians and sustainability heroes!

Did you know that 1/3 of the world's food goes to waste every year? That’s not just bad for the environment—it also affects families, economies, and our planet’s future.

In this WebQuest, you will become a Data Detective and use the power of statistics and probability to uncover the truth about food waste in your community and find ways to stop it.

Task

1. Investigate the causes and effects of food waste in homes and schools.

2. Collect and analyze real data on food waste in your community.

3. Use math (graphs, averages, and probabilities) to explain the problem.

4. Design a campaign (poster, video, or presentation) to raise awareness and suggest practical solutions.

Your mission is to prove that math can make a difference in creating a sustainable world.

Conclusion

Conclusion

Be the Change!

By the end of this WebQuest, you’ll have learned how to:

  • Use math to solve real-world problems.

  • Work as a team to analyze and present data.

  • Advocate for sustainability in your own community.

And most importantly—you'll know that even as a student, you can make a difference.
