The big idea
Earth orbits the Sun along a slightly elliptical path, completing one revolution in about 365.25 days.
Gravity continuously bends Earth's motion into an orbit. The average Earth-Sun distance is about 150 million kilometers.
◉
HOW SCIENTISTS KNOW
Precise position measurements, planetary predictions and spacecraft navigation confirm Earth's orbit.

!A COMMON WRONG MODEL
Earth Orbits the Sun is only a name or picture to memorize.
✓REBUILD IT WITH EVIDENCE
Connect earth orbits the sun to the observable relationship, evidence and system described in the lesson.
A scientifically true sentence can still create a false picture. This repair makes the relationship visible.
Take learning into real life
Try it together
Use a ball as Earth and a stationary flashlight as the Sun. Rotate only the ball, mark one home location and explain what changes there. Connect what you notice to earth orbits the sun using orbit and revolution.

Three things to remember
✓Earth orbits the Sun along a slightly elliptical path, completing one revolution in about 365.
✓Gravity continuously bends Earth's motion into an orbit.
✓Evidence matters: precise position measurements, planetary predictions and spacecraft navigation confirm earth's orbit.
