Product Description

The STEMAids Twenty Rock Specimen Collection brings 20 rock samples together for comparative geology study. Learners can observe colour, grain size, texture, layering, visible minerals and other surface characteristics before consulting a verified identification key.

Physical specimens help students connect geological terminology with real materials. Teachers can use the collection to introduce igneous, sedimentary and metamorphic rocks, provided the supplied specimens represent those groups. Exact rock names, dimensions, preparation methods and classifications must be confirmed from the approved packing list.

Frequently Asked Questions

What is a twenty rock specimen collection used for?

It is used to observe, compare and classify rock samples during supervised geology and Earth science lessons.

Which twenty rocks are included?

The individual rock names have not been verified. Publish the complete list only after checking the approved STEMAids packing record.

Does the collection include all three main rock types?

Coverage of igneous, sedimentary and metamorphic rocks has not been confirmed. The classification of every supplied specimen should be verified before publication.

Is the collection suitable for schools?

Yes. It is suitable for supervised geology, geography, Earth science and general science activities.

Are the specimens natural rocks?

The origin and preparation of the samples have not been confirmed. Buyers should verify whether the rocks are natural, trimmed, polished or mounted.

How should rock specimens be stored?

Keep every sample dry, separated and correctly labelled. Proper storage reduces damage, contamination and misidentification.
