Space is big! Just how big is difficult to comprehend. One starting point on the journey to attempt to understand how big space is is to look at the distance between the Sun, the Earth and Moon. If you have a few spare minutes, a 25 meter measuring tape and access to a printer (to print two A4 pages) you can make your own simplified model of the Sun, the Earth and Moon.
Using this resource with your students would allow you to achieve part of one of the following elaborations from either the Year 3 or the Year 5 The Australian Curriculum, Science / Science Understanding / Earth and space science content areas.
- Year 3 Elaboration 4: Modelling the relative sizes and movement of the sun, Earth and moon (ACSSU048).
- Year 5 Elaboration 2: Modelling the relative sizes and movement of the sun, Earth and moon modelling the relative size of and distance between Earth, other planets in the solar system and the sun (ACSSU078).
