Used for measuring the temperature of liquids, air, and other materials. ScienceWorkshop Version.
A 400 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Determines the current through the sensor by measuring the voltage across the internal resistor.
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
LED Light Source with adjustable brightness control, for use with Millikan Oil Drop Apparatus.
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
Allows students to study the behavior of a physical pendulum in either harmonic or chaotic motion.
Allows students to measure angular velocity, acceleration, centripetal forces, and other full range of motion experiments.
Measures the gas pressure in a closed or open system (container or atmospheric pressure).
