Discovering the Solar System

Discovering the Solar System takes young learners on the grandest journey possible — out beyond the atmosphere, past the Moon, through the inner planets, across the asteroid belt, and into the vast outer reaches of our cosmic neighbourhood, where gas giants the size of a thousand Earths drift through the darkness billions of kilometres from the Sun. Over four weeks, children explore the science, history, and breathtaking scale of the solar system through rich informational content, engaging activities, and creative projects designed specifically for ages 5–8.

The unit weaves together astronomy, physics, earth science, history of science, reading, and mathematics in a way that makes the incomprehensibly vast feel genuinely accessible and exciting. Children discover how our solar system formed from a spinning cloud of gas and dust 4.6 billion years ago, what makes each planet unique — from the crushing atmospheric pressure of Venus to the diamond rain of Neptune — how gravity holds every moon, planet, and asteroid in its precise orbital path, what the difference is between a planet, a dwarf planet, a moon, an asteroid, and a comet, and how human beings have sent spacecraft to every planet in the solar system and beyond. The science of space is simultaneously humbling and exhilarating — and this unit brings that sense of wonder directly to the kitchen table.

Each week builds on the last — from the foundational question of what the solar system is and what it contains, through the individual characteristics of each planet and the most dramatic features of our cosmic neighbourhood, to the history of space exploration and the extraordinary men and women who made it possible, and finally to the future of human space travel and what discoveries may still await us in the outer reaches of our solar system and beyond. Along the way children practise counting, addition, measurement, reading comprehension, vocabulary, sorting, classification, and creative thinking — all set against the backdrop of the most spectacular environment in the known universe.

Activities include vocabulary bingo with astronomy terms, a sorting activity distinguishing inner planets from outer planets and other solar system objects, a timeline tracing the history of space exploration from Galileo's telescope to the James Webb Space Telescope, a matching game pairing planets and space missions with their defining characteristics, a movement math lab inspired by planetary orbits, rocket launches, moonwalks, and asteroid spins, and a creative design activity where children design their own space mission including destination, spacecraft, crew, and scientific goals. The unit closes with a board game review and a showcase presentation, giving children the chance to share everything they have discovered about the magnificent, mysterious, and endlessly surprising solar system we call home.
