Ck12.org shares a variety of ways for students to learn about topics in nuclear chemistry.

 Each activity, from making atoms visible with cloud chambers to using licorice to demonstrate radioactive half-life, is classroom-tested to improve nuclear science understanding. Shared by the Center for Nuclear Science and Technology Information.

These exercises, lab investigations, videos and demonstrations focus on the fundamentals of chemical, mechanical, nuclear and gravitational energy. Energy Foundations for High School Chemistry was developed by high school teachers and the American Chemical Society. 

Dr. Sara English discusses the basics of nuclear chemistry with a bit of atomic structure review. Topics such as atomic number, atomic mass and isotopes are reviewed while new concepts like the strong force and the stability of nuclei are introduced. This video (8 min) is hosted by YouTube.

This video (5 min.) explains nuclear half life. Created by Tyler DeWitt, research scientist, author and high school chemistry teacher. It is hosted by YouTube.

These practice worksheets on nuclear energy are shared by Evan Silberstein, writer and science teacher in East Ramapo, New Jersey.

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. 

Transmutation among elements, isotopes, calculating half-life, radioactive decay, and spontaneous fission are the topics addressed in this episode (10 min.) of Hank Green's Crash Course video series. This may be especially useful for teachers flipping their classes or for students who need additional review of these topics. Disclaimer: Hank speaks very quickly, teachers interested in using this with students may want to annotate the video using an app like VideoAnt.

This nuclear chemistry review with practice problems is shared by the University of North Carolina at Chapel Hill. 

The atomic archive website explores the complex history surrounding the invention of the atomic bomb.
