Physical Science (Charlotte Mason)

Charlotte Mason wrote that the science a child should learn first is the science they can actually see. Not the version on a textbook page with arrows and labels, but the version on the counter — the ice that melts in the glass, the salt that vanishes into the broth, the candle that burns down and seems to disappear. This nine-week program follows that principle through the entire 5-PS1 NGSS standard set, but the order is always the same: the phenomenon comes first, the language comes after, and the child does most of the talking through narration and a nature notebook.

Week 1 starts with properties — the testable, observable things that distinguish one piece of matter from another. Your child holds, weighs, scratches, and dissolves real materials, then narrates what they noticed in their own words. Week 2 brings the three states of matter through an ice cube experiment and a winter morning at a Vermont sugarhouse where steam rises off the boiling sap. Week 3 moves into the kitchen for mixtures and solutions — narrating the cooking that happens in any home, then learning to pull mixtures apart again through filtering and evaporation.

Conservation, Change, and the Way Matter Moves (Weeks 4-7)

Week 4 reaches one of the great principles of science — matter is never lost — and reaches it through Lavoisier’s question about a burning candle. Your child narrates the experiment and watches the same principle hold in salt-water dissolving, melting ice, and a pot of broth simmering down. Week 5 takes on the harder distinction between physical and chemical change through an autumn morning of small changes: frost on the grass, milk going off, an apple turning brown on the cutting board. Week 6 grounds the science in craft — an old clay cup, the right material for the job — and asks how seeing matter clearly is part of how humans take care of the world. Week 7 pulls back for the long view: the oldest water in the world, one carbon atom moving through a hundred million years, the water cycle and rock cycle and carbon cycle all falling out of one principle.

Investigation and Close (Weeks 8-9)

Week 8 hands the work back to your child. A passage on the scientist’s notebook and a sample page from a real child’s nature journal give them a model for designing and recording their own investigation — the Mason version of the scientific method, which is closer to attention than to procedure. Week 9 is a capstone narration and review: a conversation with matter that pulls all four standards together through observation-based assessment instead of multiple-choice drilling.

Each week includes living-book passages, narration prompts, hands-on observation exercises, a nature notebook entry, and full answer keys with notes for the adult reading alongside. The pacing is one worksheet per day for a five-day track, or three worksheets for a flex track if you need a lighter week. Common Core 5-PS1-1 through 5-PS1-4 is covered in full, but the child won’t be moved through it on a textbook schedule — they’ll move through it the way a child should move through anything alive.
