Rocks (set of 20) in Plastic Tray Box Loose Specimens

“Rocks (set of 20) in Plastic Tray Box Loose Specimens” is a practical geology kit providing 20 individual rock specimens, stored in a compartmentalized plastic tray or box, with each sample loose (not glued or mounted), allowing for direct handling and examination.​

Product Features

Specimen Diversity:

Includes 20 different rocks representing three primary groups: igneous (granite, basalt, pumice, obsidian), sedimentary (sandstone, shale, limestone, conglomerate), and metamorphic (marble, slate, gneiss, quartzite, etc.).​

Rocks are typically hand-sized or chip-sized; some sets may vary in shape, color, or hardness for comparative learning.​

Plastic Tray and Packaging:

Sturdy plastic tray or box with individual slots or compartments for each sample, preventing mixing and allowing organized storage.​

Loose format means specimens can be lifted, observed from all sides, and tested for properties (streak, hardness, luster, etc.) without restriction.​

Usually housed in a box with a transparent or fitted lid, sometimes included in a multicolor outer carton for easy transport and storage.​

Educational Use:

Designed for geology or earth science practicals in schools and colleges, as well as for hands-on science projects at home.

Students can directly sort, classify, and make property observations (texture, grain, color, etc.), supporting inquiry-based and experiential learning.​

Often comes with an identification handbook or specimen key to help link samples to names and rock types.​

Practical Advantages:

The loose format is ideal for demonstrations, group activities, and repeated use—rocks can be examined under a hand lens or microscope as needed.

This kit is a cost-effective, flexible resource for anyone beginning rock identification, promoting tactile and visual skills in geology.
