What Determines and Limits an Atom's Mass?
Provide learners with the tools to further understand nuclear energy and isotopes. Young chemists investigate the components of an atom's nucleus, use symbols to represent various isotope forms, and use the percent abundance of an atom's...

The Atom, Atomic Number, Mass Number, and Isotopes
Expose your chemistry learners to atomic theory. As they view this PowerPoint, they will learn about subatomic particles, atomic number, and mass number of atoms as well as how isotopes are structured. Throughout this neat and accurate...

New Review What Can You Learn From Ancient Skeletons?
Skeletons may not be able to speak, but they can still tell us a lot. High schoolers watch a short video about the ways biological anthropologists can use a skeleton's bone structure to determine age, gender, place of birth, and social...

Isotopes and Atomic Mass
Some isotopes are unstable, or radioactive, meaning they will decay over time and turn into another isotope or stable element. In the interactive simulation, participants manipulate elements to create isotopes and gather information....
