Density & Buoyancy Lab

Learning fit

Labels show who asserted each claim.

A density and buoyancy lab for ages 10-15. Sink or Float? offers six true-density presets (foam 0.2, pine 0.6, ice 0.92, a neutrally buoyant 1.0 water twin, brick 2.0, aluminum 2.7 g/cm3) plus a build-your-own mass/volume bench; floaters submerge by exactly their density ratio, so ice shows only its tip. Boat Builder shows a steel lump sinking but floating as a hull, with cargo capacity differing honestly by hull shape. Density Column layers honey, water, and oil with a 3-question check.
