Physics Lab
tubes used for sound labs
to help calculate the speed of sound,

Air Track
creates a friction free surface to observe accel of gravity, newtons law
kinimatcis (vbelocity and accelerations ) other sensors to conservation of energy labs and work energy labs

Combinations multi task devices
varioable resistor but can be used as a solenoid (run current through it and measure the magnetic field)

Triple Beam Balances
measure mass, along with digital scales
