In Year 8, students have embarked on an exciting journey through space and time as part of their study of the solar system and Earth’s history. This unit goes beyond facts and figures, encouraging students to reflect on humanity’s unique place in the universe and our responsibility to care for our planet.

The learning began with Carl Sagan’s famous “pale blue dot” reflection, a powerful reminder of Earth’s small and fragile existence within the vastness of space. Using Sagan’s words for inspiration, students have considered their role as stewards of our interconnected home.

To bring these big ideas to life, the class created a scaled model of the solar system. Unlike traditional diagrams, this hands-on activity demonstrated the enormous distances between planets, underscoring the vastness of space and the life-sustaining power of the sun at the centre of it all. You can watch the unravelling of the model solar system in action through the linked image below. As you do, bear in mind that, to fit the entire solar system onto a single toilet roll just under 20 meters long, students had to scale the sun’s diameter to only 4 mm, meaning the Earth’s diameter measured a minuscule 0.4 mm.

In addition, students explored Earth’s history using the “24-hour clock” model, in which the planet’s 4.5 billion years are condensed into a single day. Humanity’s arrival in the final moments before midnight served as a powerful illustration of how brief, yet impactful, our presence on Earth has been.

Through this unit, students have considered how lessons from the past and knowledge of the universe might help shape a sustainable future for generations to come.
