Density Physics Mastery

Process physical measurements by converting SI-prefixed units, writing values in scientific notation, and rounding calculated results to the correct number of significant figures.

Evaluate measurement quality by selecting suitable instruments, distinguishing accuracy from precision, identifying anomalous data, and recommending practical improvements.

Classify physical quantities as scalars or vectors and represent vector quantities with correctly labeled arrows.

Calculate density, mass, or volume from two known quantities using the density equation and appropriate units.

Analyze a density investigation by choosing methods for regular and irregular solids, presenting the measurements on an appropriate labeled graph, and determining density from a best-fit slope.

Analyze how temperature and changes of state affect density, predict sinking or floating from relative densities, and calculate the fraction of a floating object above and below a liquid’s surface.
