Quick Answer: This set of 5 calibrated rock specimens gives students consistent, reproducible samples for density and specific-gravity measurement practice in physics and geoscience labs.
Product Description
The Calibrated Rocks for Density Set of 5 is designed for hands-on volumetric and density-calculation exercises in secondary, vocational, and introductory university science courses. Because each specimen in the set is a distinct rock type with a different density, students can practice the water-displacement method, mass-to-volume calculations, and specific-gravity comparisons across a genuinely varied sample set rather than repeating the same measurement on a single rock. The set works well for small-group lab stations, since five specimens can be rotated between benches or used together in a single density-ranking activity.
Because results depend on careful measurement technique rather than certified reference mass values, the set is best suited to teaching the density calculation method itself: measuring mass on a balance, determining volume by displacement, and calculating density as mass divided by volume, then comparing calculated values against each other and against typical published density ranges for each rock type.
Specimen Details

Applications
- Density and specific-gravity calculation practice using mass and volume measurement
- Water-displacement method demonstrations
- Comparative rock-density ranking activities across a set
- Physics and geoscience lab stations for small-group rotation
Care & Handling
Dry specimens thoroughly after any water-displacement measurement before returning them to storage, since prolonged moisture can affect softer or porous rock types over time. Handle with clean, dry hands to avoid transferring oils that can affect surface texture, and store specimens in a padded tray or divided box to prevent chipped edges between classes.

Frequently Asked Questions
1. How many specimens are included in this set?
The set contains 5 individual rock specimens, each a different rock type with a distinct density.
2. What method should students use to measure density?
The water-displacement method is recommended: measure mass on a balance, determine volume by the change in water level when the specimen is submerged, then calculate density as mass divided by volume.
3. Is this set suitable for university-level teaching?
Yes, it works well for introductory university physics and geoscience labs in addition to secondary and vocational courses.
4. Are the specimens the same size?
Specimens are supplied as natural rock pieces of a size suitable for handheld measurement; exact dimensions vary by rock type since they are natural material, not machined to a uniform size.
5. Can this set be used for a density-ranking activity?
Yes, comparing calculated densities across the 5 specimens is a common classroom exercise that reinforces the mass/volume relationship.
6. How should the specimens be stored between classes?
Dry specimens fully after any water-based measurement and store them in a padded tray or labelled box to prevent damage and mix-ups between sets.
