Introducing Measurements in the Laboratory

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric shapes. Next, scholars measure the volume of a sample of water in different beakers, test tubes, and cylinders to compare the accuracy. Scholars move on to determine the mass of solids with two types of balances and finish the laboratory with measuring the melting point of an unknown solid.
