A liquid can change shape, a solid can bend, and a gas can be invisible. Matterling helps students use mass, volume, and other properties instead of relying on appearance when classifying matter and explaining state changes.

Meet Matterling, your vocabulary training guide
Matterling is logical, curious, versatile. This Gemling guides learners through Matterport Depot and connects to the specimen Clear Quartz. The same approved character appears in the printable packet and its matching science adventure.
What the seven worksheets cover
Start with the main Matter vocabulary worksheet. Then work through these six lessons in adventure order:
- What Matter Is
- Solids & Their Properties
- Liquids & Their Properties
- Gases & Their Properties
- Measuring & Comparing Matter
- Changing State & Conserving Matter
The overview introduces matter, mass, volume, solid, liquid, gas, property, particle, melting, freezing. Each lesson narrows the focus to its own science words and ideas.
Every worksheet combines a short Gemling teaching note, a word bank, definition matching, three word-in-context questions, and a written field mission. Matterling closes each lesson by welcoming students to the corresponding adventure setting.
A classroom science field trip, starting at your desk
Compare descriptions of an eraser, water in two containers, and air in a balloon. Ask students which properties identify the state and which measurements would support their claim. Keep mass units and volume units visible during discussion.
Read the Gemling note aloud, model one vocabulary match, and let partners explain their word choices. Use the written mission to check understanding before entering the next online setting. After the seven pages, the Training Complete invitation gives students a clear next step into the FREE online Excavating Adventure.
Excavating Adventures is The Science Field Trip Company. These resources help transform classroom science into a field-trip-style experience: prepare with vocabulary, explore a science setting, explain evidence, and carry curiosity into real-world observation.
Teaching point to make clear
Flexible does not mean liquid, and invisible does not mean absent. Evaporating water still exists as gas. Conservation claims need a clearly defined system, especially when matter can leave an open container.
Download and printing details
The free PDF contains 16 separate US Letter pages: one teacher guide, seven student worksheets, one Training Complete page, and seven matching answer keys. Print at 100% scale. The activities are black-and-white friendly; students do not need color to answer. Sample written answers allow for other scientifically accurate responses.
Take the training into the free adventure
Matterling invites your class into Matterport Depot. Use the exact subject adventure below, pause to discuss clues, and encourage students to revise their thinking after feedback. The game needs an internet connection but no purchase, account, or physical kit.
ENTER THE FREE MATTER ADVENTURE
After the mission, the optional Discover, Identify, Collect continuation connects learning with real specimens. Finishing online does not record a physical discovery or mean that a specimen has been collected.

Two questions to discuss with your class
Why does being invisible not prove that something is not matter?
Air is invisible but has mass and occupies space. Visibility alone does not decide whether something is matter.
Why can a sealed syringe of air be compressed more easily than one filled with water?
Gas particles have much more space between them. A liquid has much less empty space to reduce.
