Density of soap

The morning laboratory includes a pot of coffee.
In laboratory one, soap, some bars with a density less than one gram per cubic centimeter and some with a density of more than one gram per cubic centimeter, were carved into slabs of various sizes.
Their volume and mass were both measured.
Theodora working on massing a chunk of soap.

The results were then plotted on a scattergraph, one graph for each lab group. The volume on the x axis, the mass on the y axis. The slope was the density of the soap. The graphing was done in the computer laboratory using OpenOffice.org Calc software.
