Solar System, planet size to scale

thingiverse

The solar system model is built to scale, featuring all eight planets, with Mercury and Mars barely visible due to their tiny size. Most physics teachers complain that students lack a 3D perspective when it comes to learning about the universe. When viewing models of the solar system, many kids mistakenly believe the sun is much smaller than it actually is, while thinking the earth is roughly the same size as the moon. By introducing accurate scale models in classrooms from an early age, students can develop a crucial skill: visualizing objects in proportion. Lesson Plan and Activity: During any lesson about the solar system, pull out this model to showcase its remarkable accuracy. With Mercury and Mars practically invisible due to their miniature size, students will gain a profound appreciation for how small our planet truly is. If time allows, divide students into table groups, each with their own model, to estimate the relative sizes of the planets and sun. This interactive exercise can lead to lively discussions and a deeper understanding of our solar system's scale.
