Description
“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.
