Science of the Electric Grid – Reading

Summary

This middle school reading introduces students to how electricity travels from power plants to homes through generation, transmission, and distribution systems. Using accessible language and real-world examples, students learn why transmission lines carry high voltage and how transformers lower voltage for safe use.

The reading explains grid-connected and off-grid systems and explores why microgrids are important for rural and disaster-prone areas. It also addresses modern challenges including aging infrastructure, increasing demand, renewable integration, and cybersecurity.

Comprehension questions and a glossary reinforce key vocabulary and support literacy development in science classrooms.
