This experiment allows to measure the pressure under a fluid (salted water) as a function of the depth. In the proposed version it allows the measurement of the atmospheric pressure, as well as the gravitational acceleration or the density of the fluid. It requires a smartphone equipped with a barometer.

This experiment is a sort of variation of the experiment on Stevin's Law: it allows to study how the atmospheric pressure changes with altitude and open a discussion about its formulation. Is the increase of the pressure with depth linear? Or its linear behaviour has to be considered a first order approximation? It requires a smartphone equipped with a barometer and is more suitable for university students.

This document contains two experiments about the Doppler effect. Suitable for qualitative and quantitative analysis of the wavelength shift. In one case a source/observer is attached to a spring and oscillates; in another the source/observer is on a rotating platform.

In this experiment we use a clever device made of a CD or a DVD as a diffraction grating, a smartphone to measure angles (the position of the maxima in the interference pattern) and a second smartphone or a computer camera to detect the various wavelengths.
