Exploring How Materials Gain Electric Charge
Students investigate the effect of rubbing insulating materials with various fabrics and the electric...
Measuring Charge on a Conductive Sphere
Students investigate how charge distributes on the surface of a conductive sphere and the relationship...
Electrostatic Charging Methods
Students investigate three methods of charging objects (by friction, by contact, and by induction) and demonstrate conservation of charge
Coulomb's Law
The dependence of the Coulomb force on charge and distance is explored and the Coulomb Constant is determined.
Bridge Vibrations
To study the resonant modes of a tied arch bridge, the bridge is first hit with a hammer or your hand. An FFT of the resulting vibrations are examined...
Telescope and Microscope
Students construct an astronomical telescope, a Galilean telescope, and a compound microscope on the optical bench. Using a viewing screen with grid, they...
Reflection and Refraction
Students experimentally derive the Law of Reflection for curved and flat mirrors. Snell’s Law is explored and the index of refraction for a piece of...
Mechanical Waves
Standing waves in strings and air columns are studied. Using a sine wave generator to drive a string vibrator, the driving frequency, length, density,...
Magnetic Forces on Current-Carrying Wires
The magnitude and direction of the force on a current-carrying wire in a magnetic field is measured....
Speed of Light
This experiment uses the Foucault Method to determine the speed of light. Laser light passes through a series of lenses to produce an image of the light...
