2nd grade science worksheet: sort milk, a pencil, and helium into solid, liquid, or gas, then write properties for an apple, a teddy bear, and a rock.

Hiking-trip cloze for 2nd grade science: students fill ten gaps with property words such as waterproof and absorbent, then write a sentence of their own.

Professor Pip's lab mix-up: 2nd graders sort 15 materials such as sand, honey, and a coin into solids and liquids, with a key that explains the tricky ones.

2nd grade guided notes for 2-PS1-3: students count pieces, take a build apart, and make a new object from the same set, with model notes in the key.

11-question heating and cooling check for 2nd grade: sort changes, judge melted chocolate and a frozen leaf as reversible or not, and argue about cake.

2-PS1-1
“Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.”
2-PS1-3
“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.”
2-PS1-4
“Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.”
2-PS1-2
“Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.”
