Constructing Explanations and Designing Solutions
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 phenomenon and designing solutions.
Make observations (firsthand or from media) to construct an evidence-based account for natural phenomena. (2-PS1-3)
PS1.A: Structure and Properties of Matter
Different properties are suited to different purposes. (2-PS1-3)
A great variety of objects can be built up from a small set of pieces. (2-PS1-3)
Energy and Matter
Objects may break into smaller pieces and be put together into larger pieces, or change shapes. (2-PS1-3)
