Learners use beans to investigate isotopes. In this isotopes, relative abundance and atomic mass lesson plan, students separate different beans and take the mass of each group of beans which represent isotopes. They count the total number of each type of bean which represent atoms. They calculate the relative abundance of each isotope, the mass of each isotope and find the atomic mass of each element.
