Rutherford Simulation.  How did Rutherford figure out the structure of the atomic nucleus without looking at it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.

Photoelectric  Effect.  See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.

Models of Hydrogen Simulation.  How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting photons and alpha particles at the atom. Check how the prediction of the model matches the experimental results.

 Different Emission Spectra Simulation.  Produce light by bombarding atoms with electrons. See how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.

Spectral lines. Explains observed lines and shows different elements

Blackbody Radiation Simulation.  How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change. View the color of the peak of the spectral curve.
