States of Matter
by Anonymous
Watch the particle arrangement and heating curve to see why the temperature pauses at 0 and 100 °C while the number of particles and the mass stay the same.

About this app
States of Matter is an interactive middle school science activity about how particle arrangement changes between solids, liquids, and gases. Students explore a particle model, heat ice while following a temperature curve, and predict how mass and volume change during freezing and boiling. The app emphasizes that particle count remains constant during a state change and that mass is conserved in a closed container.
Use cases
- Middle school students learning states of matter
- Science teachers introducing particle models
- Classroom practice on heating curves
- Review of mass conservation during phase changes
Features
- Compare particle arrangements in solids, liquids, and gases
- Explore shape, volume, particle spacing, and a fixed set of 12 particles
- Add heat one step at a time or five steps at once while viewing the temperature curve
- Identify temperature plateaus at 0°C and 100°C during melting and boiling
- Predict mass changes in closed and open containers and volume change when water freezes
