Content descriptor model cyclic changes in the relative positions of the Earth, sun and moon and explain how these cycles cause eclipses and influence predictable phenomena on Earth, including seasons and tides

Elaborations

• • Elaboration using physical models or virtual simulations to explain how Earth’s tilt and position relative to the sun causes differences in light intensity on Earth’s surface, resulting in seasons
• • Elaboration examining the effect of the gravitational attraction of the moon and the sun on Earth's oceans and describing how the relative positions of the moon and sun with respect to Earth result in tidal variations
• • Elaboration using physical models or virtual simulations to explain the cyclic patterns of lunar phases and eclipses of the sun and moon
• • Elaboration researching knowledges held by First Nations Australians regarding the phases of the moon and the connection between the lunar cycle and ocean tides
• • Elaboration investigating First Nations Australians’ calendars and how they are used to predict seasonal changes
• • Elaboration researching First Nations Australians’ oral traditions and cultural recordings of solar and lunar eclipses and investigating similarities and differences with contemporary understandings of such phenomena
