This set of blocks, developed by Jodye Selco, is an excellent complementary set to Density Blocks I.

Perfect for density experiments, use this set determine the mass and volume of each sample and graph the mass versus volume. The slope of the straight line that results is the density of the material.

Great for teaching that density depends of both mass and volume, students can't seem to put these spheres down! Two steel spheres are great for teaching the skills of observation and deduction.

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.
