Science Update: Exploring the Solar System

This term in Science, our students are diving into an exciting unit on the solar system. They are learning how the Earth revolves around the Sun and rotates on its own axis. As part of this, they are building models to represent these movements and observing how day and night, and seasons, are created through these motions.

In class, students constructed model systems that show Earth rotating and orbiting, helping them visualise why we have day and night and the length of seasons. They also explored how the Sun is the centre of our solar system and provides essential energy to our planet.

This learning is aligned with the new Science and Technology K–6 Syllabus (2024) outcomes for Stage 2:

• ST2-SCI-01: Uses information to investigate the solar system and the effects of energy on living, physical and geological systems. 

NSW Curriculum

• ST2-PQU-01: Poses questions to create fair tests that investigate the effects of energy on living things and physical systems. 

NSW Curriculum

We encourage you to ask your child about their model and the movements of the Earth. You might ask: “Why do you think day and night occur?” or “How long does it take Earth to make a full revolution?” These conversations help reinforce their understanding and connect classroom learning to the real world.

Thank you for your continued support in your child’s scientific exploration. We look forward to sharing more of their great work with you soon!
