The Sun is a bright star that gives Earth light and warmth. Young learners see the Sun every day, so it is a great way to begin learning about space and weather. The Sun helps us know when it is daytime and makes many outdoor activities possible. Plants, animals, and people all depend on the Sun in important ways.
The Sun looks small in the sky, but it is much bigger than Earth. Its light travels through space and reaches our planet, helping plants grow and keeping Earth warm enough for life. The Sun also helps create shadows and can make things feel hotter on sunny days. Learning about the Sun helps students connect science to the world they see around them.
