The document discusses different measurement units and how to calculate mass, length, width, and volume. It provides examples of measuring the mass of objects in grams and liquids by subtracting the mass of an empty container. It also demonstrates how to calculate the volume of an object by multiplying its length, height, and width. Students are instructed to work in groups measuring the mass and length of objects and volume of other objects.
