Types of Ionizing Radiation Lab and Simulation

Radioactivity is a topic in chemistry that can be difficult to teach if you are looking for a hands-on, data-driven approach. Safety and cost concerns often prevent students from having an inquiry-based experience with the topic. In this post, I will share how I am able to give my students an authentic lab experience for them to determine there are three types of ionizing radiation without direct instruction.

Extension Activity with Isotopes Matter

After receiving positive feedback from Peter Mahaffy, the IUPAC project co-chair of Isotopes Matter, I decided to add an additional component to the original isotope assignment I posted. The second component of the assignment focuses on the applications of both radioactive and stable isotopes using the interactive IUPAC periodic table.
