  • Description
  • Scope of Supply

Pressure differences at the top and bottom of bodies immersed in a medium result in net forces on the body, which reduce the weight force within the medium.

  • Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
  • Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
  • Increased motivation of students by using the intuitive measureAPP.
  • Increased media competence.


  • Determine the buoyancy of bodies from the difference of their weight forces in air and water.
  • Calculate the density of bodies from their weight in air and the volume of displaced water.

Learning Objectives
Students should understand how static buoyancy affects the body. The apparent reduction in weight under water can be used to determine the volume and density of an unknown body. The underlying relationships should be understood both physically and mathematically.
