In this PhET sim inquiry-based activity, students define isotope using mass number, atomic number, and number of protons, electrons, and neutrons. They will find the average atomic mass of an element by determining the mass of its isotope. This includes comprehensive data on atoms and isotopes. It could be used as a lab demonstration or homework activity. The accompanying simulation can be found here: https://phet.colorado.edu/en/simulation/isotopes-and-atomic-mass
