92-Atom Molecular Model Set Subject_Physics dropping resistance as temperature rises

dropping resistance as temperature rises and giving an introduction to temperature-dependent semiconductor sensors

suited to fieldwork in geography units and orientation activities outside the classroom

and diatom preparations for microbiology and protist-identification work

anchoring side-by-side magnet-strength comparisons for the classroom

Designed for liquid-fill Snell's-law work at smaller scale
