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 should
be expressed as a "the - the " statement by the students.
In the experiment itself the scale of the hydrometer will be
calculated and then the density of various liquids will
- Real stand material for an esecially stable and safe setup
- Student-suitable experiment descriptions with reports available
