Build the key vocabulary of Water’s States, Density, and Phase Changes with this printable picture flash card set for Grade 6 science, aligned to Virginia Science SOL. It covers 15 essential terms, from Water’s States, and Density to Thermal Energy. Each term comes as a picture-and-word card and as a picture card with a clear, full-sentence definition, and two labeling worksheets let students show what they know.

What students practice

• Water’s States,
• Density: Density describes how much mass is packed into a certain volume; ice is less dense than liquid water.
• and Phase Changes
• Solid: A solid has a definite shape and volume; ice is water whose molecules remain arranged in a relatively fixed structure.
• Liquid: A liquid has a definite volume but takes the shape of its container because its particles can move past one another.
• Water Vapor: Water vapor is water in its invisible gas state, with molecules spread farther apart than in liquid water.
• Melting: Melting is the change from solid to liquid when a substance gains enough thermal energy.
• Freezing: Freezing is the change from liquid to solid as thermal energy leaves the substance.
• Evaporation: Evaporation changes liquid water into water vapor at the surface, often below the liquid’s boiling temperature.
• Density,
• Condensation: Condensation is the change from water vapor to liquid water when the vapor cools sufficiently.
• Boiling: Boiling changes liquid to gas throughout a liquid when its vapor pressure equals the surrounding pressure.
• Sublimation: Sublimation changes a solid directly into a gas without passing through the liquid state.
• Deposition: Deposition changes a gas directly into a solid without passing through the liquid state.
• Thermal Energy: Thermal energy is the energy associated with the random motion of particles within a substance.

What’s included (10 pages)

• 15 color picture-and-word cards
• 15 picture–term–definition cards (4 pages)
• 15 black-and-white picture-and-word cards for low-ink printing or coloring
• 2 picture-labeling worksheets: students write the matching term for each picture (with Name and Class lines)

How to use it in class

1. Print the color cards (or the black-and-white set to save ink), cut them apart and laminate them to reuse.
2. Introduce the words with the picture-and-word cards, then use the definition cards to talk about what each term means.
3. Play quick games: show a picture and ask for the term, read a definition and ask which card it matches, or sort the cards into groups.
4. Use the labeling worksheets as an exit ticket, homework or review, and check them with the answer key.
5. Put the cards in a word wall or science center for independent practice.
