Our work today involved a Counting By Weighing activity. Students recorded the mass of a small number of objects to then estimate the mass of a much larger number of objects. The activity was designed to help students begin to make sense of the mole, a unit of chemistry that represents 6.02 x 10^23 of any given object. In chemistry, we use the mole as a way to measure the number of atoms or molecules. Students also received a copy of the Chapter 13/14 Study Guide as a tool to begin preparing for the quiz next Tuesday.
