Tired of blowing up countless balloons to illustrate orbital shapes around an atom? Give your lungs a break and use an interactive instead! Learners observe s, p, d, and f orbitals through the first four energy levels using hydrogen as a...

When molecules of hydrogen and oxygen are combined, how does water form? Science scholars observe changes in kinetic and potential energy during a chemical reaction in an interactive. The resource features easy controls that allow users...

It's molecule magic! Skillful scholars explore the effects of different atoms on molecular polarization using an intuitive interactive. The resource displays the charge at different locations on the molecule, then adapts as the user...

Aquapores allow water to travel through cell membranes while keeping other molecules out. The animation offers an up-close look at these parts of the cell membrane. It explores multiple vantage points and shows the importance of these...

How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.

An explanation of Niels Bohr's (1885 - 1962 CE) Model along with an app that illustrates a hydrogen atom according to the particle or wave model. You can choose a principal quantum number "n." The right part of the graphic represents the...
