# Fire2Fusion

> Fire2Fusion is an energy-education reference site for students, teachers, and parents. It explains every major type of energy in plain language, with grade-banded sections for younger and older students, quizzes, FAQs, worksheets, and cited sources on every page.

Content is written for classroom and homework use in US grade bands K-2, 3-5, and 6-8, aligned with NGSS energy standards (4-PS3, MS-PS3). Every page lists its references and a last-updated date.
