What is the Sun?

  • The Sun is a big ball of hot gas in the sky.
  • It gives us light and heat, which are very important for life on Earth.
  • Without the Sun, the Earth would be cold and dark.
  • The Sun is much bigger than the Earth and is found at the center of our solar system.

Examples:

  • When you feel warm on a sunny day, that's the Sun's heat making you comfortable.
  • Plants need sunlight to grow. They use the Sun's light to make food through a process called photosynthesis.
  • At night, when the Sun goes down, it gets dark, and that's why we need lights to see.

Fun Fact: The Sun is so big that about 1.3 million Earths could fit inside it!
