> Physical quantities

Physicists try to describe and explain everything from galaxies to quarks. The measurement of physical quantities is an essential part of the toolkit for this work. Making simple measurements of quantities such as mass, length and time can provide students with a good introduction to more complex and sophisticated physics.
