About this resource
Description
Everything a child can see, hold, pour, or breathe is matter, and matter shows up in three familiar forms: solid, liquid, and gas. A solid keeps its own shape, a liquid pours and takes the shape of whatever holds it, and a gas spreads out to fill its whole container. This states of matter worksheet gives third graders a clear, hands-on way to practice telling those three forms apart using ordinary classroom and kitchen materials rather than abstract definitions.
This solid liquid and gas worksheet opens with a word box of nine everyday materials and a three-column sorting chart labeled Solid, Liquid, and Gas. Students read each word, decide which form it takes, and write it in the matching column. The second half moves the skill into reading: four sentences each name one solid and one liquid, and students find both and write them on the labeled lines. Use it as a lesson warm-up, an independent practice page, a science center task, or a quick check before a unit test.
What’s Included
- 1 print-ready PDF worksheet
- Answer key
- A nine-word sorting chart with Solid, Liquid, and Gas columns
- 4 sentence items with two labeled answer lines each
There are three reasons this page helps children learn the skill. First, sorting real materials such as wood, honey, and oxygen ties an abstract science idea to objects a child already knows, so the definitions stick. Second, the sorting chart is a graphic organizer, which means students can see all three categories side by side and compare them instead of memorizing them one at a time. Third, the sentence section asks students to apply the skill inside connected text, which is exactly how a states of matter worksheet question appears on a science assessment.
Teachers and parents can stretch this lesson well past the page. Set three labeled bins on a table and let children sort real objects into them, then talk about why a sponge is still a solid even though it squishes. Fill a balloon and ask what is inside it that no one can see. Freeze water, melt the ice, and boil a little of it on the stove so students watch one substance travel through all three forms. Send children on a home hunt for one solid, one liquid, and one gas, and have them draw what they found in a science notebook the next morning.
