Free energy lessons, printable worksheets, quizzes, and diagrams for K-8 science teachers. Mapped to NGSS standards 4-PS3 and MS-PS3. No signup needed.
Everything on Fire2Fusion is free to use in your classroom. No accounts, no downloads to unlock, no watermarks. Print any page, project it on the board, or assign it as reading. This page maps our content to the standards and grade bands you teach.
Every energy page follows the same structure, so students always know where to look. A Quick answer section gives the definition and key facts up front. A “For younger” section explains the idea for K-5 readers, and a “For older” section adds the formulas and depth middle schoolers need. Each page ends with a quiz your students can take right on the page, an FAQ, and the sources we used.
4-PS3 Energy (Grade 4). Students learn that energy comes in forms, moves between objects, and converts from one form to another.
| Standard focus | Start here |
|---|---|
| Energy and speed (4-PS3-1) | What is kinetic energy?, Kinetic energy diagram |
| Energy transfer by sound, light, heat, current (4-PS3-2) | What is light energy?, What is sound energy?, Electrical energy to heat |
| Energy in collisions (4-PS3-3) | Potential and kinetic energy |
| Energy conversion devices (4-PS3-4) | How water energy works, Electric energy generation |
MS-PS3 Energy (Middle school). Students work with kinetic and potential energy quantitatively and track energy transfer.
| Standard focus | Start here |
|---|---|
| Kinetic energy, mass and speed (MS-PS3-1) | Kinetic energy equations, Kinetic energy diagram |
| Potential energy and position (MS-PS3-2) | Electric potential energy, Potential and kinetic energy |
| Thermal energy transfer (MS-PS3-3, MS-PS3-4) | Electrical energy to heat energy |
| Energy conversion (MS-PS3-5) | Electric energy equation, What is hydro energy? |
K-2 (K-PS3, 1-PS4). For the youngest students, use the “For younger” sections on these pages: Light energy for kids, Kinetic energy for kids, Geothermal energy for kids, Wave energy for kids.
Every page prints cleanly: navigation, ads, and quiz buttons drop out automatically, leaving the content and diagrams. Current dedicated printables:
More worksheets are on the way. If you want one for a specific energy type first, tell us through the About page.
Electric, Atomic, Kinetic, Light, Water, Sun, Gas, Geothermal, Air, Wave, Sound, Oil, Hydro
Every page lists its references, shows a last-updated date, and gets reviewed for accuracy against sources like the U.S. Energy Information Administration, the Department of Energy, and NASA. Read more on our About page.
