States of Matter is a Grade 3 science worksheet with 15 multiple-choice questions that introduces matter and compares its three main states: solid, liquid, and gas. Students identify everyday examples, recognize that matter makes up objects, air, water, and living things, and match each state to its defining properties. Questions address definite shape, taking the shape of a container, pourability, and particle spacing, including items that use images to represent solids and gases. The worksheet also checks students’ understanding of basic changes of state by asking what happens when an ice cube melts. It provides a focused way to review vocabulary, observable properties, and simple particle-level descriptions before or after classroom instruction. This free printable worksheet is designed for Grade 3 science practice, review, or formative assessment and includes a complete answer key for efficient checking.

This Grade 3 science worksheet uses 15 multiple-choice questions to build understanding of matter and its three main states: solid, liquid, and gas. Students identify examples, connect solids with definite shape and closely packed particles, recognize that liquids take the shape of their containers, identify gases and widely spaced particles, interpret state-of-matter images, and determine that melting changes ice into a liquid.
Introduce the worksheet after students observe classroom examples such as a solid object, a pourable liquid, and air or another gas. Have students explain the property behind each answer—such as definite shape, taking a container’s shape, or particle spacing—rather than choosing from memory alone. Use the image-based questions and the final melting question as prompts for students to connect visible examples with changes of state.
Students may confuse an object’s material with its state, select liquid for any substance that can be seen, or overlook that a liquid takes the shape of its container rather than having a definite shape. They may also reverse the particle-spacing descriptions for solids and gases, misidentify image-based examples, or choose freezing or evaporation instead of melting when ice becomes liquid.
Wayground provides this states-of-matter worksheet as a printable PDF and as a digital quiz, so you can use the 15 multiple-choice items for paper practice or online assessment. A complete answer key is included for checking responses, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also offers an option for schools that are reducing screen time.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the multiple-choice options, particle descriptions, and image-based questions are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when that better supports access to the states-of-matter vocabulary.
