Jennifer Heider-Kasberger is from Seattle, Washington and has been at AIS-Salzburg since 2008. She is known for developing close bonds with students — evident in the many photos of her hugging students at award ceremonies — and delivering heartfelt speeches to students at the end of the school year. Her colleagues also really appreciate the tasty brownies she leaves out at the front office!
The purpose of this experiment was to investigate Archimedes’ Principle for an object that is denser than water. Archimedes’ Principle states that an object floating or fully immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. The buoyant force on an object immersed in a liquid can also be determined by weighing an object in air and then in water. The apparent loss of weight of the object is equal to the buoyant force of the water. With this information, the students were able to determine the mass density of the different objects and of the fluids.
