Earth's Tilt and Orbit
Model Earth's yearly trip around the sun with its axis always tilted the same way.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 3
- Earth does two things at once. It spins on its axis every day, and it travels around the sun in a path called an orbit, once a year.
- Earth's axis isn't straight up and down. It's tilted, and the tilt always points the same way, all year long.
- Look at June. The north end of the axis leans toward the sun. In December, on the other side of the orbit, the same tilt leans away from the sun.
- Georgia is in the north half of Earth, the Northern Hemisphere. So in June, Georgia leans toward the sun and gets long days.
Georgia Standards of Excellence in Science:
- S4E2.a β Develop a model to support an explanation of why the length of day and night change throughout the year.
- S4E2.c β Construct an explanation of how the Earth's orbit, with its consistent tilt, affects seasonal changes.
