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. This simulation of a Rutherford Scattering is from the Physics Education Technology website of University of Colorado. Included are links to related topics and additional ideas and activities for teachers to use.
