AP Day 14

After reviewing the results of Friday's measuring activity, students took a mid-unit quiz on measurements, sig figs and conversions. This was followed with a discussion of sig fig use in calculations, as well as density and percent error calculations.

The following PhET Simulation can be used for practice in solving for the various quantities represented in the Density equation (D, m & V).  The Mystery section challenges you to determine what material each block is made of, based on measured masses & volumes and provided reference values.
