Me 4.2 Pression hydrostatique

Principle

The students should determine the directional independence of hydrostatic pressure (termed as top, lateral and bottom pressure) with the aid of 3 hydrostatic pressure probes.

Additionally, they should measure the hydrostatic pressure as a function of immersion depth ...

Me 4.3 Poussée et flottabilité

Principle

The students should determine whether or not various objects float in water. They should then investigate whether the volume of an object or its shape affect its buoyancy.

 

Benefits

  • Student-suitable experiment descriptions with reports available

Le principe d'archimède

Principle

The students should determine the weight (force) of an object in air and then in water. From the difference they should calculate the buoyancy Fb

In a second experiment, the students should determine the mass of the water displaced by the immersed object; from this ...

Me 4.5 Densité des corps solides par mesure de la poussée

Principle

In this experiment the students should recognize that the density of solid objects can be determined by measuring only the buoyancy. The required computations can be given or worked out by the students on their own, in part as an additional Task.

Benefits

  • Real stand ...

Me 4.6 Mesure de la densité de liquides avec un aréomètre

Principle

The students should use the knowledge gained from the experiments "Buoyancy" and "Archimedes' principle" to be able to construct a hydrometer.

The correlation between density and immersion depth is to be determined in a preliminary experiment, the results of which ...

Me 4.7 Densité de liquides non miscibles

Principle

Using the knowledge gained in the experiments "Buoyancy and floating" and "Finding the density of solid bodies by measuring the buoyancy", the students should determine the density of petroleum ether in a water-filled U-tube.

After rearranging the given formula they ...

Me 5.3 Oscillation d'une lame-ressort

Principle

In the previous experiments, the students determined the oscillation period of a spring and of a thread pendulum, and its dependence on the mass. They also determined the spring constant and pendulum length respectively.

In this experiment they should establish the ...

We 1.1 La sensation de chaleur par la peau

Principle

In this experiment the students should determine that the heat sensitivity of their skin does not allow a reliable estimation of the temperature. Its estimate is, on the contrary, dependent on which temperature was available previously for comparison.
