12pm to 2pm - Taught by Mark Kent, MS
Geared for ages 7 to 13, please wear closed toed shoes in the lab.
What will we do?
Hydrometers are used to determine the specific gravity, or the density of a liquid. It consists of a scale that tells if the density of the liquid is higher or lower than water, and the level at which the hydrometer floats is only dependent on the density of the liquid.
Archimedes of Syracuse was an Ancient Greek (http://en.wikipedia.org/wiki/Ancient_Greece) mathematician (http://en.wikipedia.org/wiki/Mathematics), physicist (http://en.wikipedia.org/wiki/Physics), engineer (http://en.wikipedia.org/wiki/Engineering), inventor (http://en.wikipedia.org/wiki/Inventor), and astronomer (http://en.wikipedia.org/wiki/Astronomy). One important work was his treatise on hydrostatics and fluid mechanics, ‘On Floating Bodies (http://en.wikipedia.org/wiki/On_Floating_Bodies)’, in which he stated his principle: any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. This can also be stated as follows: any floating object displaces its own weight of fluid.
In this class we will be building and testing hydrometers.
