Buying Guide

Match specimen to lesson goals

Choose specimens that illustrate the concept you teach—resin insects for morphology, tungsten cubes for density, and preserved scorpions or spiders for taxonomy

Consider durability and handling

Resin-encased specimens and framed displays resist breakage and repeated handling better than wet or loose samples for classroom use

Prioritize safety and storage

Use sealed displays or vials for hazardous or allergenic specimens and confirm proper labeling and storage instructions are available

Assess demonstration versatility

Choose items that support multiple activities—density cubes for measurement labs, sodium polyacrylate for absorbency demos, and framed insects for identification

Verify specimen authenticity and preparation

Look for real preserved specimens or certified materials and clear descriptions of preservation method (resin, wet vial, framed mounting)
