Overview

Reducing food waste

"Fresh Food In Garbage Can to Illustrate Waste" by SpeedKingz/Shutterstock.com

Have you ever thrown away food after a meal? Have you ever thrown away a whole piece of food? What are some of the reasons you threw away that food?

During this Food Waste Audit, students will explore their own impact on our food system. Students will brainstorm solutions to reduce their food waste and be challenged to try out their solution!

NGSS Alignment

This lesson helps students prepare for these Next Generation Science Standards Performance Expectations:
  • MS-ESS3-3. Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
This lesson focuses on these aspects of NGSS Three Dimensional Learning:

Science & Engineering Practices Disciplinary Core Ideas Crosscutting Concepts
Constructing Explanations and Designing Solutions. Constructing explanations and designing solutions in 6–8 builds on K–5 experiences and progresses to include constructing explanations and designing solutions supported by multiple sources of evidence consistent with scientific ideas, principles, and theories.

Apply scientific principles to design an object, tool, process or system.
ESS3.C: Human Impacts on Earth Systems. Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But changes to Earth's environments can have different impacts (negative and positive) for different living things.

Typically as human populations and per-capita consumption of natural resources increase, so do the negative impacts on Earth unless the activities and technologies involved are engineered otherwise.
Cause and Effect. Relationships can be classified as causal or correlational, and correlation does not necessarily imply causation.

Connections to Engineering, Technology, and Applications of Science

Influence of Science, Engineering, and Technology on Society and the Natural World. The uses of technologies and any limitations on their use are driven by individual or societal needs, desires, and values; by the findings of scientific research; and by differences in such factors as climate, natural resources, and economic conditions. Thus technology use varies from region to region and over time.
