The Sun, Our Nearest Star

The sun has been shining on our planet for millions of years. It gives us light and keeps us warm. Without the sun, there would be no plants or animals. Without the sun, there would be no life on Earth. What is the sun? the sun is a star. It is out daytime star, the star closest of all to Earth. Find out what the sun is made of. Find out how hot it is, how far away it is , and how long it takes for light from the sun to reach Earth. Do an experiment to prove that light from the sun makes things grow. All you need are two paper cups, soil, water, some beans, and some sunlight. Distinguished science writer Franklyn M. Branley and artist Don Madden team up t take a look at a star that is very important to us--the sun.
