Isotopes, mass number and relative atomic mass
In the first lesson students use the hook of Ramesses II and carbon dating to introduce the idea of isotopes. Following the PowerPoint, students test their knowledge with a series of questions.

In the second lesson students use sodium as an example to explore the idea of relative atomic mass. Students run through calculating relative atomic masses from isotope abundances and use their knowledge to answer the questions.
