Description: In lower elementary science, students will learn that objects are made of pieces which can be disassembled and reassembled into new objects. The pieces that most students are familiar with are Legos. A good way to use this phenomenon is to ask your students the following question: "What are the 10 most useful Lego bricks?" or "What are the 10 most common Lego bricks?" The answer is less important than the idea that object are made of pieces (2-PS1-3) and that properties of different materials are used for different purposes (2-PS1-2).
