Complete Calorimeter Set Biology_Entomology & Zoology one fitted with an exploder

one fitted with an exploder piston for impulse experiments

filled with iron filings whose alignment renders 3D field lines around any bar magnet up to 0

Speed-controlled 6V motor driving two cams pumps four spring-mass systems at any chosen frequency

the unit also runs as a motor on 6-8V DC for energy conversion demos

sized for finer-gauge resistance demonstrations and small-scale heating elements where the heavier gauges would over-deliver current

Complete Calorimeter Set Biology_Entomology & Zoology one fitted with an exploderDouble vessel copper calorimeter set with a 75 by 50mm inner cup on cork supports inside a 100 by 75mm outer shell and a slotted lid, the air gap damping heat loss during measurement.
