Demonstrate understanding of the effect on the Earth of interactions between the Sun and the Earth-Moon system
This standard is about how the positions and movements of the Sun, Earth, and Moon cause things we observe on Earth — like seasons, tides, day and night, Moon phases, and eclipses. Students sit a written exam at the end of the year worth 5 credits. The exam has three questions with diagrams and data, and asks students to describe, explain, and analyse these astronomical interactions.
You can name the seasons in order, describe that summer is warmer than winter, explain day and night, name most Moon phases, state how long the Moon takes to orbit Earth, and define terms like equinox and solstice. You describe what happens but may not fully explain why.
You explain WHY the Southern Hemisphere has four seasons by linking it to differences in solar radiation. You explain how the Moon's changing distance from Earth (perigee and apogee) affects its appearance, and you explain how the Sun's angle changes shadow length at a specific location. You make clear links between science ideas and observations.
You discuss in depth why Wellington's monthly temperature changes throughout the year, tying everything back to solar radiation. You use Earth and Moon movements to explain why a super full moon is rare. You compare how latitude differences between places like Dunedin and the Equator lead to different shadow lengths and daylengths, integrating multiple ideas together.
