General No. I Microscope Slide Set, 25-Piece Item Type_Shaker supplying two voltmeter scales on

supplying two voltmeter scales on one accessory so students switch between low and mid-cell voltages without rewiring

demonstrating that electrostatic charge concentrates most densely at the tip where surface curvature is highest

sized to detect small currents flowing in either direction during induction

letting students watch the wire travel along the rail as roughly 3A of current crosses the magnetic field

Shows oxygenated and deoxygenated blood paths between heart chambers and alveolar surfaces through seven hand-painted removable parts designed with medical-professional input
