Constant Mass Density Blocks Set
Model Number: MTM-42
The Constant Mass Density Blocks Set from Micro Technologies is designed to demonstrate the relationship between mass, density and volume using specimens of approximately equal mass. The set contains nine blocks—pine, maple, PVC, nylon, acrylic, aluminium, copper, brass and steel—with each specimen having an approximate mass of 20 g. The different block sizes provide a clear demonstration of how material density affects volume. An instruction manual is included.
Product Specification
The Constant Mass Density Blocks Set from Micro Technologies is a practical laboratory specimen collection developed to help students investigate the relationship between mass, density, volume and material type.
The set consists of nine different material blocks, each designed to have approximately the same mass of 20 g. Because the mass remains approximately constant while the material changes, the physical size and volume of each specimen vary according to its density.
The nine included materials are pine, maple, PVC, nylon, acrylic, aluminium, copper, brass and steel. This combination provides examples of woods, polymers and metals within a single experimental set.
The fundamental relationship demonstrated by the apparatus is:
Density = Mass ÷ Volume
When mass is held constant, the relationship can also be considered as:
Volume = Mass ÷ Density
Therefore, materials with a higher density require a smaller volume to achieve the same approximate mass, while materials with a lower density require a larger volume.
The wooden specimens, pine and maple, provide useful examples of relatively low-density natural materials. Their physical dimensions can be compared with denser polymer and metallic specimens.
The set includes three polymer specimens—PVC, nylon and acrylic—allowing students to compare synthetic materials with both natural woods and metals.
Four metallic specimens—aluminium, copper, brass and steel—provide a broad comparison of commonly studied engineering metals.
The differences in specimen size make the density relationship visually apparent even before quantitative measurements are performed.
Students can measure the length, width and height of individual blocks using a suitable ruler or Vernier Caliper. These measurements can then be used to calculate specimen volume.
A laboratory balance may also be used to verify that each specimen has an approximate mass of 20 g.
Using experimentally determined mass and volume, students can calculate the density of each material and compare their results with appropriate reference values.
The set is particularly useful for explaining why two objects can have the same mass but significantly different physical dimensions.
It can also support material-identification exercises. Students may calculate the density of a coded or unknown specimen and compare the result with reference density values to determine its likely material.
When used alongside a Constant Volume Density Blocks Set, students can investigate two complementary concepts: equal-volume specimens exhibit different masses, while equal-mass specimens exhibit different volumes.
This comparison provides a more complete understanding of the relationship between mass, volume and density.
The collection can support lessons in properties of matter, material science, dimensional measurement, density calculations and comparative material properties.
An instruction manual is included to support structured laboratory activities and demonstrations.
Manufactured and supplied by Micro Technologies, the Constant Mass Density Blocks Set is suitable for physics laboratories, material science laboratories and educational institutions requiring practical apparatus for density and volume investigations.

FAQs
What is the Constant Mass Density Blocks Set used for?
The set is designed to demonstrate the relationship between mass, density and volume using different materials having approximately the same mass.
How many blocks are included in the set?
The complete set contains nine different material blocks.
What is the mass of each block?
Each specimen has an approximate mass of 20 g.
Which materials are included?
The set includes pine, maple, PVC, nylon, acrylic, aluminium, copper, brass and steel.
Are all the blocks the same size?
No. The specimens have approximately equal masses, but their sizes and volumes differ because the materials have different densities.
Why do equal-mass blocks have different volumes?
A higher-density material requires less volume to provide the same mass, whereas a lower-density material requires a greater volume.
Which metal specimens are included?
The set contains aluminium, copper, brass and steel metal blocks.
Which polymer specimens are included?
The polymer specimens are PVC, nylon and acrylic.
Can students calculate density using the blocks?
Yes. Students can measure the dimensions to calculate volume, verify mass using a laboratory balance and determine density using Density = Mass ÷ Volume.
Is an instruction manual supplied?
Yes. An instruction manual is included with the set.
