Understanding Capacity and DIY Lava Lamp

Ms. Coker introduces third graders to the concept of capacity, focusing on U.S. customary units like cups, pints, quarts, and gallons. She provides visual examples using everyday items and guides students through a DIY lava lamp activity to reinforce learning. The lesson concludes with a challenge to identify capacity units in household items.
