Moho
This animation simulates what Andrija Mohorovičić observed in 1909 - that seismic waves travel faster in the mantle than they do in the crust because it is composed of denser material.

Atomic and ionic structure of the first 12 elements
This animation provides the planetary and quantum view of the electron configuration for the first 12 elements on the periodic table. In addition, users can select a view of the nucleus of each atom and configuration of the major ion formed by the atom. Simply click on an element from the table above to proceed.

Acceleration during Free Fall
Demonstration of how the rate of acceleration of an object is independent of the object's mass, showing two objects with different masses falling at the same rate (if we ignore air resistance).

Overview of Photosynthesis
Overview of Photosynthesis provides a short illustration of the light-dependent reactions that take place in a chloroplast during photosynthesis.
Energy Movement Through Photosynthesis
Overview of the Photosystem II reaction, which is the first step of photosynthesis. Shown is how a chlorophyll molecule (p680) uses light energy to take an electron from a water molecule, generating ATP and leading to Photosystem I.
Dalton's Playhouse
Dalton's Playhouse simulates the experiments conducted by Priestley and Lavosier that led to Dalton's theory of matter.

Bohr's Atom
Neils Bohr proposed that electrons resided in specific orbitals within atoms in his groundbreaking work on atomic theory. This animation allows you to add different amounts of energy to see how the electron in a hydrogen atom responds, and then manually allow that electron to relax to specific orbitals within the atom.
