Electric circuits

Electric fields

flash-lampIn this activity students use the voltage sensor to measure the potential across a capacitor as the capacitor discharges. They determine the time constant of the circuit. They investigate the effect of changing the capacitance of the capacitor and changing the resistance of the resistor on the time of discharging

Activity Discharging a capacitor (demo)

Electromagnetic induction

Forces and Newton's Laws of Motion

Gas laws

Harmonic motion

Heat and temperature

coolingIn this activity students record temperature during a cooling process of hot water and check the validity of Newton's law of cooling for the collected data

Activity Newton’s law of cooling (demo)

Motion in one direction

young woman jogging front cement wall101010In this activity students record motion graphs. They are asked to walk in front of the Motion detector and a graph of distance vs. time is being plotted real-time on the computer or data-logger screen during their motion. Students are asked to interpret resulting graphs.

Activity Graphing distance (demo)

matchIn this activity students walk in front of the motion detector to match the given distance vs. time graph

Activity Match the graph (demo)



music-sound-wavesIn this activity students use the sound sensor and record sound waveforms from tuning forks.

Activity Sound waves (demo)

lightningIn this activity students determine the speed of sound in air. There are two measuring methods offered in the activity. Depending on an interface a different method can be used

Activity Speed of sound (demo)
