I can	Red	Amber	Green
Particles and density
Compare state properties through particle movement and arrangement and explain density differences, including ice.
Calculate and rearrange density, mass and volume and convert between common unit systems.
Explain mass conservation and changing volume or density during reversible physical state changes.
Density practical
Describe density measurements for regular solids, irregular solids and liquids using appropriate volume methods.
Explain measurement quality using zeroed balances, meniscus readings, complete immersion, repeats and trapped-bubble errors.
Heating and state changes
Distinguish temperature from internal energy and explain heating effects on particle kinetic and potential energy.
Define specific heat capacity and calculate temperature-change energy or rearranged quantities with correct units.
Define specific latent heat and calculate melting or vaporisation energy without a temperature change.
Name state changes and interpret heating or cooling plateaus using particle potential energy and latent heat.
Calculate energy for separate warming and state-change stages and explain methods of reducing thermal losses.
Water investigations
Describe the water heat-capacity practical using mass, electrical energy, temperature rise, stirring and insulation.
Describe melting-ice temperature-time measurements and explain flat and imperfect plateau regions.
Gases and temperature
Explain gas pressure and qualitative temperature effects for fixed gas mass at constant volume.
Describe absolute zero, convert Celsius and kelvin readings and distinguish readings from temperature differences.
