The Next Generation Science Standards provide educators with Performance Expectations for students to meet at each grade level. Science practices like “planning and carrying out investigations” and “analyzing and interpreting data” were common in the days of inquiry. Because high-quality children’s books are an integral part of each Perfect Pairs lesson, students will glean much more than an understanding of essential science concepts as they complete the lessons. When the children have finished their drawings, ask the class to gather for a Science Dialogue. Invite students to share their drawings with the class. As each child presents, the rest of the class should think about whether the animal uses a body part, a behavior, or both to stay safe.
