Physics
Free-fall apparatus
This experimental equipment can be used for experiments with the movement of objects, and it can thus be used to determine the gravitational acceleration g based on the fall time and the fall length, as the following relationship applies:
where h is the drop height.h

Fuel cell, ethanol
This fuel cell kit with propeller contains a fuel cell that produces power from an ethanol solution of up to 15%. This makes it possible to investigate how the effect from the fuel cell changes with different ethanol solutions. There is also the option of making power outlets for other power consumption, e.g. bulbs or motor. A pH paper is included to examine changes in the pH value in the residual product from the energy process with the ethanol used.

Physics
Function generator
This function generator is developed and produced by Frederiksen Scientific and is suitable for, for example, experiments with standing waves or for studying sound waves at different frequencies. The generator can run through frequencies in intervals of ten decades from 0.001 Hz to 10.00 MHz with a tolerance of just 0.005%.
