The sun is a huge, hot, bright star. It is important because without it there would be no life on Earth. The
sun gives us light and heat.
All living things need light and heat from the sun to live. Plants need light and heat to grow. They use the
light from the sun to make food. We cannot make our own food, but plants can. All the food we eat comes
