In second grade science, Mrs. Oligmueller’s students spend one unit learning about pebbles, sand and silt. It’s during this lesson that students have the opportunity to work with table partners to discover and discuss what properties and identifying characteristics make rocks individually unique.
Throughout the lesson, students focus on observing and sorting rocks based on their properties and discuss how different river rocks are similar to each other. Students then partner up and use their observation skills to sort the river rocks by a single property such as size, shape, color, texture, or pattern.
According to Mrs. Oligmueller, “Students love this unit on rocks where they get to do many hands-on investigations. They also love being able to bring in rocks from their own collections!”
