Review on 🔬 Precision Density Cube Set - Metals with 10mm Sides by Justin Vasquez

I used these building blocks to teach two different age groups (4th grade through high school) about metal density. Because all six cubes have the same volume (1 cubic centimeter or 1 milliliter) but different weights, they were ideal for teaching students both density and the metric system. They come in a nice snap-on case. I highly recommend them for science or physics classes!
