Decoding DTMF Tones
Students will use a wireless sound sensor and the fast Fourier Transform (FFT) display of the data collection software to analyze the tones produced when...
Measuring the Speed of Sound with an Echo
Students will first predict the speed of sound in the air of their classroom using a simple relationship...
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...
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...
Magnetic Field Strength
Students use a magnetic field sensor to measure the magnetic field at the center of a coil at five different current levels. Students plot magnetic field...
Blockly Extension: Acoustic Stopwatch
Students develop Blockly code that uses data from a Wireless Sound Sensor to trigger start and stop...
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...
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...
Simple Pendulum
Students test different variables to see which affect the period of a simple pendulum.
Rotational Collisions
Students measure the change in angular velocity when a rotating disc experiences a sudden change in rotational inertia.
