In this 5th-grade science lesson, students will explore the properties and changes of matter, focusing on the three states: solid, liquid, and gas. The lesson begins with a discussion to define matter and its different states, followed by group activities where students observe various materials' physical properties. They will then engage in hands-on experiments to witness changes in states of matter through the melting of ice in warm water and the expansion and contraction of air in balloons. Through these activities, students will learn to identify characteristics of matter and understand how temperature affects state changes. The lesson concludes with a recap of key concepts and a homework assignment where students will find real-life examples of matter changing states at home. Assessment will be based on observations during group work and the quality of the homework assignment. Safety precautions will be emphasized throughout the activities.
