Science questions about day and night sky for kids.

📚 Quick Study Guide

🌍
• Earth's Rotation: The Earth spins on its axis, an imaginary line passing through the North and South Poles. One complete rotation takes about 24 hours, which we call a day.
☀️
• Day and Night: As the Earth rotates, different parts of the planet face the Sun. The side facing the Sun experiences day, while the side facing away experiences night.
🌃
• Stars: Stars are giant balls of hot, glowing gas. They appear as tiny points of light in the night sky because they are very far away.
🔭
• Constellations: Constellations are patterns of stars that have been given names by ancient cultures. They help us find our way around the night sky.
🌙
• The Moon: The moon orbits the Earth and reflects light from the sun. This is why we see the moon at night.
