Matter and Its Interactions
Your child should understand that things can be taken apart and rebuilt into something new — the pieces don't change, just the arrangement.
What the standard actually says
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.
Domain: Matter and Its Interactions — Exploring how different materials have different properties and how heating/cooling can change them.
Next Generation Science Standards*Examples and home activities
- Build something with LEGOs, take it apart, build something completely different.
- Discuss recycling: 'This plastic bottle can be melted and made into something new!'

Lessons that teach this
4 lessons list 2-PS1-3.
Week 6
- Monday · Science — Students will show that a set of small pieces can be taken apart and built into a new object and review how properties describe matter (2-PS1-3, 2-PS1-1).
- Wednesday · Science — Students will explore cutting and folding paper into new objects and review reversible changes with the Week 4 play dough (2-PS1-3, 2-PS1-1).
- Friday · Science — Students will review the Properties of Matter unit by sorting, changing and building with materials and create a mosaic from small pieces (2-PS1-3, 2-PS1-1).
Week 36
- Friday · Science — Students will present their science portfolio, reflect on their growth as a scientist, and receive awards tied to real skills demonstrated during the year (all Grade 2 science standards reviewed).

Your child should be able to observe, describe, and sort materials by properties like color, texture, hardness, flexibility, and whether they absorb water.
2-PS1-2Your child should test materials to figure out which one works best for a job — like 'which material makes the best umbrella?'
2-PS1-4Your child should know that heating and cooling can change materials — and sometimes you can undo the change (ice melting) but sometimes you can't (cooking an egg).
