【Product Description】

Set of four (4) types of metal cubes (Aluminum, Steel, POM (plastic), and Wood) with different masses and densities but with the same size (3 x 3 x 3cm).

【Overall Advantages to Users】

Helps students understand the concept of density by providing them a hands-on activity that makes it much easier to realize the difference between volume, density, and weight.


  • Properties of matter
  • Finding density through mass and volume.
  • Discovering various densities of different materials.




【To all users】

Possible to give students a hands-on activity if they place each one of the blocks on their palms one after another and discover the identity of the blocks on their own.

【To teachers】

Stored in a plastic box in which each block has its own compartment that minimizes corrosion and/or scratches.
