With this remote experiment students will understand the principle of objects floating and sinking in liquids, study the Archimedes Principle – displacement of liquids by floated objects, weight in liquids, buoyancy force. The laboratory is easy in use allowing to employ it for younger students (10-12 years old) as an observation tool for floating and sinking objects and for older ones (16-18 years old) to design the own experiment to determine the density of the objects.
