Ten Specimen Density Set Cube for Periodic Table Collection (Ten Piece/Cube/Block)

These were better than expected. There were some reviews calling them small(!!!) and I was prepared to be disappointed.They came labeled correctly, size is a good for any density experiment and I am not sure what the negative reviews have been about.

Perfect size for the experiment. Great materials. I like how the names are marked.

The pieces are great. I used it for a density lab with my middle school science class

I bought this set for my daughter's school Archimedes' project. One of the cubes was damaged. I contacted a manufacturer and they sent a replacement cube right away.Very nice people. They even explained how to weight a partially submerged cubes.

These are an awesome way to teach density

The quality of the kit is disappointing. My aluminum came very scratched up, my copper was oxidized, and also the Iron is coated in a black paint rather than a clear coat. Some of the woods are chipped and the mat that the set comes with is made of cheap foam that is cut all the way through, so the block don't sit on the foam they sit on whatever is underneath, even the cutouts in the foam aren't straight.

Ridiculous, way too small.

Fantastic! They look sharp and get the point across to my students perfectly.
