Earth's Orbit Model

Earth's Orbit Model

Last week, O started quizzing me on the sun and moon.
"Do the sun and moon get together?"

Though they don't really 'get together', they certainly work in harmony and play vital roles in our universe.
Among a million other incredible (and simple) space lessons, I came across this Orbit Model from 'More Time 2 Teach' http://moretime2teach.blogspot.ca/2013/02/earths-orbit-misconception.html
Not only does it demonstrate size and comparison in a mini math lesson, it's a creative tactile tool for showing how the moon orbits the earth and the earth orbits the sun (fitting snugly into our concepts of calendar and lunar years from last week).
