The First Great Lesson is a captivating tale that takes us on a journey through time to explore the awe-inspiring beginning of the universe. This story sparks the curiosity and imagination of Montessori students, laying the foundation for a profound understanding of the world around them. Through hands-on demonstrations, children will witness how solids and liquids came together to shape the continents and oceans, leading to a comprehensive study of various scientific disciplines.

The Story of the Coming of the Universe and the Earth

Once upon a time, before time even existed, there was nothing but darkness and emptiness. Then, in an event of unimaginable brilliance, the universe was born. A cosmic explosion known as the Big Bang brought forth all the matter and energy that make up everything we know today. The universe expanded, galaxies formed, and stars were born, scattering their light across the cosmos.

Among the countless stars, one particular star shone brighter than the rest – our sun. It became the centre of our solar system, surrounded by planets, moons, and comets. The third planet from the sun was Earth, and it was a remarkable place.

At first, Earth was a seething ball of molten rock, as hot as the core of a star. But as time passed, it began to cool down, and its surface solidified. This marked the beginning of a breathtaking transformation.

The first oceans formed as rain fell upon the cooling Earth, and over time, the continents emerged like giant puzzle pieces. As the continents drifted, collided, and split apart, they shaped the world as we know it today. The Earth’s crust danced with immense forces, creating mountains, valleys, and deep ocean trenches.


The story of the universe’s birth leads us to explore astronomy, where we learn about the solar system, study the planets, admire distant stars, and marvel at galaxies millions of light-years away. Children will be fascinated by the wonder of comets and the beauty of constellations that have inspired humans for millennia.


The Earth’s journey wouldn’t be complete without understanding its dynamic atmosphere. Through meteorology, students will learn about the wind’s influence, the ocean currents’ flow, and the wonders of weather patterns, fronts, and the water cycle. They will explore the magic of clouds and the power of glaciers in shaping the land.


In our exploration of the universe and Earth’s story, we encounter the fundamental principles of chemistry. Children will investigate the states of matter, witness changes and mixtures, and delve into the realm of elements, atoms, molecules, and chemical reactions through hands-on lab work and experimentation.


The forces that govern the universe also shape our daily experiences. In physics, students will explore magnetism, electricity, gravity, light, sound, and heat. They will conduct experiments to understand motion, friction, and energy, fostering a deeper appreciation for the laws of the physical world.


As we delve into the Earth’s past, we encounter the fascinating world of geology. Children will study different types of rocks and minerals, learn about Earth’s incredible landforms, and discover the causes and effects of volcanoes, earthquakes, and plate tectonics. They’ll journey through time, exploring the Earth’s history and the mysteries of ice ages and geological eras.


Finally, armed with a deep understanding of Earth’s processes and history, students will delve into geography. They will learn how to read maps and use globes, understand latitude and longitude, and explore the diversity of climates and landforms across the globe. This knowledge will inspire them to research continents and countries, fostering an appreciation for our world’s rich tapestry.


The First Great Lesson, “Coming of the Universe and the Earth,” is a powerful introduction to the wonders of the cosmos and our planet’s history. It ignites the flame of curiosity, inspiring Montessori students to explore the mysteries of astronomy, meteorology, chemistry, physics, geology, and geography. Through hands-on experiences and engaging lessons, children embark on a journey of discovery, leading them to become lifelong learners and stewards of the Earth.
