If you read through Charlotte Mason’s old school programmes, you’ll find the same short instruction printed under science, term after term: Experiments must be made. Not “may be made if you have time,” or “are a nice enrichment.” Must. It’s one of the few places where her gentle method speaks with the firmness of a requirement, and that alone should make us stop and ask why.
The answer gets at something easy to miss about science in this method. We tend to think of the living book as the lesson—the reading is the real work, and the experiment is a treat tacked on the end if the afternoon allows. But that isn’t how Charlotte Mason saw it. To her, the reading and the experiment were two halves of one whole. The book carries the idea to the child; the experiment lets him meet that idea with his own hands. Leave either one out, and science stops being living.
Two Halves of One Whole
A living science book does something a textbook cannot: it hands the child real ideas, written by someone who loves the subject, in language that invites wonder rather than memorization. But ideas about the physical world are meant to be tested against the physical world. A child can read that an electric current will swing a compass needle, and understand the sentence perfectly well—but until he builds the little circuit and watches the needle jump, the idea remains someone else’s. The experiment is how he takes possession of it.
The teachers in Charlotte Mason’s own circle understood this clearly. Writing in the Parents’ Review, one schoolmaster put it plainly: “Science is primarily a practical subject and is learnt by a growing child through his four senses, and his knowledge should grow out of his own practical experience and observation.” The danger, he warned, was letting the books carry all the weight; “we need, in fact, to keep the balance between practical field work and book work.” (A. T. L. Hickson, Parents’ Review, “Science: Nature Study”)
Another contributor sharpened the point still further. Real scientific knowledge, he said, must be “a knowledge of the things and forces; not about them. It must be obtained by personal experience.” And he was blunt about who should be doing the work: “have at least some of the experiments carried out, not by yourself, but by the students.” (D. Avery, Parents’ Review, “Cultural Value of Science”)
That is the heart of it. The experiment isn’t a demonstration the child watches us perform. It’s the child’s own encounter with the thing itself.
Experiments Must Serve the Reading
While experiments must be made, they must never be made at random.
This is where a Charlotte Mason approach parts ways with much of what passes for hands-on science today. The goal is not a drawer full of dazzling demonstrations pulled from a kit or a Pinterest board, performed because they fizz and impress. Each experiment should connect directly to what the child is reading. The questions raised by the book are exactly the questions the experiment should answer, because those are the questions the child actually has. An experiment that has nothing to do with the week’s reading may entertain, but it doesn’t teach science the way this method intends. It’s a spark with nothing to catch.
When the book and the bench are tied together, something better happens. The reading raises a question; the experiment lets the child chase it down; and the answer, having been seen, stays.
How Experiments Grow Across the Forms
Like everything in this method, experimentation begins simply and deepens as the child does.
In the early years and Form 1, there are no formal lab experiments at all. The child’s “experimenting” is his own observation out of doors—turning over a stone to see what lives beneath it, watching where the water goes, noticing which way the seedling leans. He is learning to look closely, ask questions, and look again. These are the raw habits every later experiment will depend on.
In Form 2, formal experiments begin in earnest. They are simple ones, matched to the science book of the term—a magnet and some iron filings, a few household materials. But this is the child’s first real practice at following a procedure carefully, watching a principle come to life, and noticing what actually happens. For most children, it quickly becomes the best part of the week.
In Form 3, the work matures. There are now four science lessons per week, and some of those lessons are given over entirely to an experiment. The student is working more independently; your role becomes making sure the materials are ready and the work is done with care. Most importantly, this is where experiments begin to be recorded. With the start of the science notebook in Form 3, the child no longer just performs an experiment and moves on—he writes up what he did and what he observed, and reproduces diagrams of the process.
By Forms 4 through 6—the high school years—students are conducting experiments across all four sciences, and the body of lab work they accumulate is substantial enough to stand behind a transcript credit in each. One encouragement for these years: a student should engage the ideas of an experiment even when the mathematics behind it is still beyond him. As Walter Lewin reminds us, physics is a way of seeing the world, not merely a pile of formulas. If the child can work the math, wonderful; if not, there is still a great deal to learn by observing, thinking, and discussing.
The Box on the Shelf
For all the philosophy, the single most practical reason experiments don’t happen is mundane: when the day arrives, you don’t have the vinegar, or the balloon, or the length of copper wire, and so the experiment gets put off to “next week,” and next week never comes.
The simplest fix is also the most effective. At the beginning of each term, gather all the supplies for that term’s experiments and keep them together in one box. Then, when an experiment lesson arrives, everything you need is already on the shelf. It’s a small habit, but it’s very often the difference between experiments that are meant to be made and experiments that actually are.
Not a Recipe to Follow
It’s worth saying what these experiments are not for. They are not meant to train a child to follow a recipe and arrive at the answer the book already told him to expect. That same Parents’ Review writer warned against reducing science “to the equivalent of a collection of cookery book recipes”—a string of steps performed without thought. An experiment in this method is meant to confirm an idea, deepen understanding, and move knowledge from theory into lived experience. It rewards careful attention and the willingness to give it another try sometimes.
That is why experiments must be made. Not to busy the child’s hands, and not to decorate the science lesson, but because a child who has only read about the natural world knows it at second hand. The one who has also tested it—who has watched the iron rust, closed the circuit, seen the crystal form—knows it as his own. The book gives him the idea. The experiment makes it true for him.
