Great tool to use to better explain mass, weight, and density
Bought these to help give a tangible understanding of mass, weight, and density for students and the general public during science outreach activities/events. Small, compact, and worth the money to make this concept so much easier to understand.

Cute
Thank you. These are great. I look forward to purchasing a larger set one day. Perhaps I'll look for a display stand.

Good for Metal Density Lab
They seem great so far. I tested the densities before my students and they check out pretty well. I do wish they were not stamped so there would be some mystery to it but i was able to remove the stamp of the symbols with some work. I was a bit confused on how impure the zinc may have been. I could not get the Zn to melt at the normal melting point for zinc, it was actually much higher. I was also able to fit them inside 20mL graduated cylinders with no problem for more accurate density calculations. Otherwise, great for lab but if you are wanting to collect elements, go for something a little bigger.

too small
totally misrepresented this product. I will be returning it. The samples are tiny

Wash hands after touching the lead cube!
I love these little density cubes they are super cute. I really like that they are 1cubic centimeter each it helps students understand what a cm3 is and then they can imagine why it equals 1 mL Make sure to have students wash their hands after touching the Pb cube. Mine where stamped with their atomic symbol. Interesting that brass is stamped Br but it made for a good inquiry. I wish there was an option to have stamped or not stamped for different lab options.

PERECT!
These are perfect cubes for density/specific gravity activities. The abbreviations for the metals are nicely engraved on the cubes and they are perfect 1 cm cubes as you can see in the attached photo. Either these cubes have been updated/upgraded since some of the other reviews were written or the reviews are incorrect. Don't hesitate to purchase these. They come in a small plastic case with a snap close lid.

It is better that these are NOT labeled!
My students were using Specific Heat Capacity and Density to identify their content.

Experiment manual not included.
Advertised as "EXPERIMENT MANUAL || Includes manual with background information, properties of each metal, and student activities with questions." Nothing of the sort was included in the package. The cubes are small so they are difficult for young students to use.
