This is strange request. Here goes: Finding main ideas in paragraphs was something I *always* struggled with and now I'm teaching a lesson on it. I need someone to double check the following three paragraphs. Tell me what he main idea of each one is. I want to make sure I'm correct before I teach it! Paragraph 1: The Sun has gravity. Gravity is a force that attracts all objects to one another. The Suns gravity pulls on the planets and the moons. Gravity makes the planets and the moons travel around the Sun. They follow paths called orbits. The Suns gravity keeps the solar system together. Paragraph 2: Lots of air surrounds Earth. Winds blow white clouds across the surface. The clouds are made of water drops. Eventually the drops fall as rain or snow. Water runs across the land and wears it away. Volcanoes spew out lava to make new land. Earth is constantly changing. Paragraph 3: Jupiter also has many moons orbiting it. Two of these moons, Ganymede and Callisto, are larger than the planet Mercury. Another moon has erupting volcanoes on its surface. Two other moons are ice covered, with oceans of water beneath.
