lack of supporting data
Reviewed By:  Pat
It would have been useful if the objects were identified and densities given. For homeschooling it is useful to have something to check against.

No description of cubes
Reviewed By:  Jenny
There is nothing that comes with these cubes. You'll need to figure out yourself which cubes are the aluminum, zinc and iron. The copper and brass are easy to identify. It certainly makes it difficult to use these effecitvely and accurately. No density provided.

support documentation would be nice
Reviewed By:  Kathleen
Cubes arrived without any supporting documentation - would have been great if the densities of the included metals would have been provided, particularly brass, which can fluctuate, diepending on percentage of metals in the alloy. But the cubes are a good size, and will be easy for the students to handle and measure, either using a ruler, or by using displacement method in a graduated cylinder.
