Grade 3 students participated in a Think-Pair-Share activity to understand the arrangement of particles in solids, liquids, and gases. Using colored balls in transparent bottles as particle models, they observed how particles are closely packed in solids, slightly spaced in liquids, and far apart in gases. Students thought independently, discussed with partners, and shared their ideas with the class. The hands-on activity helped them clearly visualize particle arrangement and confidently explain the differences between the three states of matter.
