Properties of Sound Waves

Students will learn the meaning of terms (frequency, period, crest, trough, amplitude, wavelength and wave speed) used to describe waves by studying sound...

High School / Physics

Rotational Dynamics

Students use hanging masses to apply torque to a rotating arm and measure its angular acceleration. After varying the torque, they experimentally determine...

Blockly Extension: Acoustic Stopwatch

Students develop Blockly code that uses data from a Wireless Sound Sensor to trigger start and stop...

High School / Physics

Capacitors and RC Circuits

Students construct a circuit that charges and discharges a large capacitor through a light bulb. They create a model for their observations and test the...

High School / Physics

DC Circuits

Students construct a circuit consisting of two resistors in series and then in parallel. They measure the voltage across the resistors, and the current...
