2-PS1-3 Matter and Its Interactions
Students who demonstrate understanding can: Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object.
Clarification Statement: Examples of pieces could include blocks, building bricks, or other assorted small objects. Provide students with the same number of objects to create a different object.
Assessment Boundary: Do not introduce terminology associated with the Law of Conservation of Matter just concepts. Chemical change is outside of this performance expectation.
Crosscutting Concepts	Science & Engineering Practices	Disciplinary Core Ideas
Energy and Matter: Objects may break into smaller pieces and be put together into larger pieces, or change shapes.	Constructing Explanations (for science) and Designing Solutions (for engineering): Constructing explanations and designing solutions in K–2 builds on prior experiences and progresses to the use of evidence and ideas in constructing evidence-based accounts of natural phenomena and designing solutions. Make observations (firsthand or from media) to construct an evidence-based account for natural phenomena.	Structure and Properties of Matter: Different properties are suited to different purposes. A great variety of objects can be built up from a small set of pieces.
