Next time you throw a ball in the air, and it doesn’t fly off into outer space, thank gravity.

This four-part video series presents a detailed review of the important concepts in middle school earth science relating to Earth-Sun-Moon system, characteristics of the inner and outer planets, and fascinating highlights of the universe.

Students take a tour of our solar system. Visit each of the planets to learn about their special features, sizes, and orbits. Learn about the planets' moons and rings, and how gravity keeps them in orbit. Stop at the sun, discover its immense size, and see sunspots and solar flares. Find out what scientists have learned about the planets through telescopes, space missions, and satellites.
