This lesson plan outlines a science lesson about the planets and moons in the solar system for a 5th grade class of 29 students. The lesson uses various hands-on activities and group work to help students learn about the eight planets, classify celestial bodies, and understand the structure of the solar system. Key activities include completing a KWL chart about what they know and want to learn, sorting flashcards of planets and space objects into groups, building a model of the solar system out of plasticine, and describing planets to each other using a substitution table with comparatives. The goal is for students to be able to identify and order the eight planets by the end of the lesson.
