Ages 5–6
Describing Material Properties
Describe simple physical properties of everyday materials such as hard/soft, stretchy/stiff, shiny/dull, rough/smooth, waterproof/absorbent, transparent/opaque

Ages 5–7
States of Matter Vocabulary
Name and distinguish the three states of matter — solid, liquid, and gas — using properties vocabulary: hard, rigid, runny, flows, keeps its shape, fills its container; use 'change of state' to describe what happens when materials are heat…

Ages 7–9
Changes & Separation Vocabulary
Use process vocabulary for changes of state and material separation — dissolve, solution, soluble, insoluble, evaporate, condense, melt, freeze, filter, sieve, mixture, separate — and understand precisely what each term describes, includin…

Ages 7–11
Drawing Particle Diagrams
Draw and interpret particle diagrams — dot representations showing the arrangement, spacing, and movement of particles in solids (close, regular, vibrating in place), liquids (close, random, flowing past each other), and gases (widely spac…

Ages 7–10
Testing Materials for Uses
Give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials including metals, wood, and plastic

Ages 9–11
Advanced Material Properties
Compare and group everyday materials based on advanced properties: hardness, solubility, transparency, electrical and thermal conductivity, and response to magnets

Ages 9–11
Material Properties Vocabulary
Use technical vocabulary to describe and compare material properties — conductor, insulator, thermal, electrical, transparent, opaque, translucent, soluble, insoluble, magnetic, flexible, rigid, density — and apply these terms precisely wh…

Ages 11–12
How Materials Change State
Explain melting, freezing, boiling, condensing, and sublimation using the particle model, interpreting heating and cooling curves to identify melting and boiling points
21 verified questions on this shelf
Ages 11–13
Physical vs Chemical Changes
Distinguish between physical changes (reversible, no new substances formed) and chemical changes (new substances formed, often irreversible), using conservation of mass to understand both types

Ages 11–13
Pure Substances & Mixtures
Distinguish between pure substances and mixtures, identify formulations as useful mixtures with precise compositions, and use melting and boiling points to test for purity
22 verified questions on this shelf
Ages 11–12
The Particle Model
Use the particle model to explain the properties of solids, liquids, and gases — including differences in arrangement, movement, and spacing — and apply the model to explain density, compressibility, and the anomalous expansion of water

Ages 12–14
Finite Resources & Recycling
Explain that many raw materials (metals, fossil fuels, minerals) are finite resources, describe the environmental costs of extraction, and evaluate the benefits of recycling and the circular economy
