Day and Night
Review that Earth spins once about every 24 hours, so each place turns into and out of the sunlight.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 1
- Welcome to Earth and Moon Orbit! Let's start with something you see every day: day and night.
- Earth spins around an imaginary line called its axis, once about every 24 hours. The half facing the sun has day. The other half has night.
- As Earth turns, your town moves into the sunlight, which is morning, and later turns away from it, which is evening.
- The sun isn't moving around us. It only looks that way because we're spinning, like trees seem to move past a car window.
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.
