Atoms to Electricity: ages 8–11
A tiny nucleus. A much bigger energy story.
Join two otter museum guides to investigate how a nuclear power station produces electricity. Count particle models, compare elements and isotopes, follow an energy pathway and assemble a paper station. Distinguish the jobs of a reactor, turbine and generator, examine simplified water loops and turn what you learn into a small museum exhibit.
20 activity pages + 4 guide, answer and reference pages.
The complete bundle. Completely free.
US Letter (8.5 × 11 inches) is ready for your home printer. A4 is also available. No email form. No separate MomoMango account.

Build a power-station exhibit
Place six machine cards on the exhibit mat and distinguish heat, steam, water and shaft connections.
A whole bundle of things to try.
Work through the atom activities before the power-station model, in several short sessions. Print the pages you need, and follow the numbered sequence for activities that build on earlier results.
Print single-sided at Actual Size or 100%. Keep pages 14–15 together for the exhibit mat and matching machine cards. Page 21 folds into a pocket museum.

A few little ways
to play.
Start with the printable. See where their imagination takes it.
Follow the energy with a finger
Trace the path through the paper station and name what changes at each stage. Keep moving water, turning machinery and electrical energy distinct.
Ask what the model leaves out
Compare a diagram with its model note. A simplified picture can explain one idea without showing every part of a real station.
Become the museum guide
Build an exhibit that explains one supported idea, then invite someone to ask a question. Use the answer pages to help explain the details.
Easy on your printer. Ready for their crayons.
Use the PDF that matches your paper, print in portrait, and check the preview before you start. Choose “Fit to printable area” if your printer clips the edges. Read our printing guide.
