In this Year 3 science lesson, students are introduced to the moon, learning that it is about one-fourth the size of Earth and approximately 380,000 kilometers away, requiring light about two seconds to travel between the two bodies. The lesson explains that the moon orbits Earth as Earth orbits the Sun, leading to the various phases of the moon visible from Earth due to its reflective properties. A creative video further illustrates these concepts by personifying the moon and explaining how it reflects sunlight, describes its phases, and invites interest in a potential moonwalk.
