What do we know about the dimensions associated with the Sun, Earth and Moon? - Presentation

The educational presentation is aimed at exploring the dimensions of the Sun, Earth, and Moon, with a particular focus on making this information accessible to Year 3 students. The unit is concise and designed to help pupils discover the size of these celestial bodies and how to effectively communicate their findings to a younger audience. It encourages the use of visual aids, such as an internet video titled "The Relative Size of the Earth, Moon and Sun," to enhance understanding. The presentation is structured to build on Year 3 pupils' existing knowledge of 'light and dark' and to present the information in a manner that is easy for them to grasp.

Some fascinating facts highlighted include the average distance from the Earth to the Moon being 384,403 km, and the average distance from the Earth to the Sun being 149,597,887 km. A comparison of these distances yields a ratio of approximately 389. Additionally, when the diameter of the Sun, which is about 1.4 million km, is divided by the diameter of the Moon, which is 3,474 km, the result is around 403, illustrating a curious numerical closeness. The presentation aims to deepen the pupils' understanding of the relative sizes and distances of the Sun, Earth, and Moon through repeated viewing of the video and note-taking, supplemented by focused worksheets on the topic.
