Study the planets with models! Use these three lessons to have your students think critically about our solar system. Order the Planets, Size the Planets, and Classify the Planets are a series of lessons that will have your students learn about the characteristics, size and order of our solar system. Students collect information by measuring, construct a chart to organize information, represent the natural world with models and analyze those models for limitations. Student recording sheets, rubrics for scoring, teacher lesson guides, teacher background, science notes and multiple-choice questions are provided.

By the end of grade 5. Some objects in the solar system can be seen with the naked eye. Planets in the night sky change positions and are not always visible from Earth as they orbit the sun. Stars appear in patterns called constellations, which can be used for navigation and appear to move together across the sky because of Earth's rotation.
By the end of grade 8. The solar system consists of the sun and a collection of objects,
including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them. This model of the solar system can explain tides, eclipses of the sun and the moon, and the motion of the planets in the sky relative to the stars. EarthÃƒÂ¢Ã¯Â¿Â½Ã¯Â¿Â½s spin axis is fixed in direction but tilted relative to its orbit around the sun; the seasons are a result of that tilt, as is the differential intensity of sunlight on different areas of the earth across the year.
