The poster has a clear central concept: The Sun is placed at the center, with Earth’s orbit drawn around it, reinforcing the heliocentric idea.

• Seasonal depiction – Shows four Earth positions (spring, summer, autumn, winter) to explain the variation in day length and seasons.

• Tilt explanation – Indicates the Earth’s axial tilt of 66° (relative to its orbital plane) and its role in seasonal change.

• Child-friendly visuals – Colorful Sun, labeled Earth images, and arrows make it easier for children to follow.
