Science of the Electric Grid

Summary

This comprehensive electric grid lesson plan introduces middle and high school students to how electricity is generated, transmitted, distributed, and managed in modern society. Students explore the three core segments of the grid: generation, transmission, and distribution, and analyze how electricity must be balanced in real time because it cannot easily be stored at scale.

The lesson includes structured reading materials at both middle and high school levels, a vocabulary and quiz section, real-world data analysis, a microgrid computation challenge, and an in-depth case study focused on Puerto Rico’s microgrid development following Hurricane Maria. Students compare grid-connected and off-grid systems, evaluate reliability and resilience, and apply scientific principles such as electromagnetic induction, energy conversion, and Ohm’s Law.

Teachers can use this as a full multi-day unit or select individual activities to supplement instruction on electricity, energy infrastructure, renewable integration, or engineering systems. The lesson supports critical thinking, quantitative reasoning, and real-world application.

Explore the Teacher Guide for facilitation strategies, the Student Guide for printable materials, and related lessons such as Science of Energy Efficiency and Science of Wind to deepen student understanding of energy systems.
