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

calculating relative humidity from the temperature difference between the two readings for meteorology coursework

sized to detect small currents flowing in either direction during induction

and energy transfer in a compression wave

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