How can particle arrangement explain a material's shape and volume?
Your discovery goalRelate a particle model's arrangement and movement to differences between solids, liquids and gases.
Mapping checkedA prediction is a starting idea. You can revise it after exploring.
Use at least 40 characters and include an observation. Your writing is saved as evidence; it is not automatically judged for accuracy.
This records completion of this demonstration. It is not an official grade or a claim of mastery.
Compare qualitative particle arrangements while keeping particle identities fixed.
Relate a particle model's arrangement and movement to differences between solids, liquids and gases.
State what you changed. Describe the result using an observation from the model. Connect the observation to the idea you are learning, then try a different case to test your explanation.

Particles vibrate near ordered sites; their neighbours remain similar. The colour and perspective size help separate particles in this drawing. They do not represent different substances. No automatic animation runs: compare successive steps.
You observe that a sample keeps its shape, while its particles vibrate around stable positions. Which representation explains these observations?
Qualitative particle representation with a fixed particle count: solid particles vibrate near lattice sites, liquid particles move within a lower region, and gas particles spread across the container. Relative motion scales with the square root of the energy control. These prescribed paths do not calculate intermolecular forces, collisions, diffusion rates or phase-transition temperatures; phase is selected separately. The energy control is not a Celsius temperature. This is a 2D projection of prescribed 3D coordinates. At zero energy these schematic particles stop; this is not a claim about absolute zero, quantum motion or actual liquid/gas stability.
