2 pagesStates of Matter — Solid, Liquid & Gas
📖 Reading Passage
Everything around you is made of matter. Matter comes in three forms. A solid keeps its shape — like a rock or a table. A liquid takes the shape of its container — like water and juice. A gas spreads out to fill all the space — like the air we breathe. You can change matter by heating or cooling it. Freeze water → solid. Boil water → gas (steam).

About This States of Matter Worksheet
This free printable states of matter worksheet is designed for students in Grades 2–4 who are learning about solids, liquids, and gases. Through sorting activities, property identification, and real-world examples, students explore the key differences between the three states. The worksheet also introduces how heating and cooling can cause matter to change from one state to another — melting, freezing, boiling, and condensing. A complete answer key is included. Print-ready on US Letter or A4 paper.
Learning Objectives
By completing this worksheet, students will be able to:
- Identify and name the three states of matter: solid, liquid, and gas
- Describe the key properties of each state — whether it has a fixed shape and fixed volume
- Sort common everyday objects and materials into the correct state of matter category
- Explain how heating and cooling can cause matter to change states, with at least one example for each direction
How Teachers Can Use This Worksheet
- With live demonstrations: Start the lesson with three simple demonstrations — show an ice cube (solid), let it melt into water (liquid), then talk about what would happen if you boiled the water (gas). Students observe all three states from a single material. After the demo, students complete the worksheet to connect their observations to academic vocabulary.
- As a sorting station: Before distributing the worksheet, have students work in small groups to sort picture cards or real objects into three categories — solid, liquid, and gas. This hands-on warm-up activates prior knowledge and makes the worksheet feel like a natural next step rather than an isolated task.
- As a unit review or quiz: After several days of instruction on matter, use this worksheet to check for understanding. The variety of question types (sorting, multiple choice, short answer) gives a well-rounded picture of each student's grasp of the topic.
How Parents and Homeschoolers Can Use This Worksheet
Before handing your child the worksheet, walk around your kitchen together and find one example of each state of matter — an ice cube (solid), water from the tap (liquid), and steam rising from a hot drink (gas). Talk about what makes each one different. Then complete the worksheet together. Afterward, try a simple experiment: freeze juice into ice pops (liquid to solid), then let one melt on the counter (solid to liquid). Ask your child to identify which change is melting and which is freezing. This hands-on activity reinforces the concept far better than the worksheet alone.
Common Core / NGSS Alignment
This worksheet supports NGSS 2-PS1-1 (plan and conduct an investigation to describe and classify different kinds of materials by their observable properties) and NGSS 2-PS1-4 (construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot).
