In this 4th-grade science lesson, students will explore the three states of matter: solids, liquids, and gases. The lesson begins with a class discussion on what matter is, followed by direct instruction where key properties of each state are defined and compared using a chart. Students will then engage in hands-on activities where they observe various materials and categorize them based on their state of matter. An experiment featuring the melting of ice and the boiling of water illustrates changes between states due to heat. Through group discussions and reflections, students will share their observations about these transformations. The lesson concludes with a brief assessment via exit slips to evaluate their understanding of the concepts covered, while also providing opportunities for differentiated learning and extensions. The goal is for students to develop a foundational knowledge of physical science and the characteristics of matter in an interactive and engaging manner.
