Meet the BFFs: Four fundamental forces

We all know something about gravity, but what about the other fundamental forces of physics? Explore the properties of two familiar forces experienced in daily life, and of two less familiar ones. How do they interact, and what keeps everything from falling apart? This video was Kate Dent's entry into the 2013 Sleek Geeks ...

Build a Nucleus

This interactive simulation explores isotopes and nuclear decay. In a series of simulations students explore how the changing the number of neutrons or protons affects the atomic number and isotope; investigate and predict how the shell model depiction of an isotope based on the isotope symbol or name; and predict the resulting ...

Isotopes and Atomic Mass

This interactive simulation explores isotopes and how the average atomic mass of an element changes given a change in the abundance of its isotopes. In a series of simulations students explore the stability of various isotopes and investigate how this relates to the proportions of isotopes in naturally occurring elements. ...
