Position, Distance, and Displacement
Students will explore and discover the difference between position, distance, and displacement using graphs of their own motion.
Newton's Second Law
Students measure the force on a cart and its resulting acceleration for a modified Atwood machine. They vary the weight on the hanger and create a graph...
Fruit Battery
Students will construct an electrochemical cell using common materials. They will explore how the voltage changes as the cells are connected in series.
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...
