The student is expected to demonstrate that Earth rotates on its axis once approximately every 24 hours causing the day/night cycle and the apparent movement of the Sun across the sky.
- The day and night cycle occurs every 24 hours due to the rotation of the Earth.
- We can demonstrate that the rotation of the Earth causes the day and night cycle.
- The Sun appears to move across the sky each day due to the rotation of the Earth.
- How often does the day and night cycle occur on the Earth?
- Describe the positions of the Earth and Sun when it is daytime. How is this different at nighttime?
- On the Earth it looks like the Sun is moving across the sky. Why is this not true?
