ice
Let an agent handle ice by form, physics, uses and safety, including thin ice on water and icy roads.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle ice by form, physics, uses and safety, including thin ice on water and icy roads.
Water frozen into a solid, forming at 0 degC at standard pressure, occurring as sea ice, lake and river ice, glaciers, frost, rime, hail and ice crystals; it is less dense than liquid water and floats.
What it is for: Climate systems, cooling, food preservation and winter activities.
It can be explain ice formation and forms; check ice safety guidance before going on frozen water; handle icy roads and paths safely; use ice safely in food and cooling.
