Rutherford's discovery of the nucleus has been described as a “black box” experiment. In order to solve the structure of the atom, Rutherford had to “unlock” the box. Rutherford shot alpha particles at atoms in a piece of gold foil and observed the scattering angles. In this activity, students confront a problem similar to the one Rutherford faced. Students shoot marbles at an unknown, unseen object. By tracing the apparent path a marble takes after striking the unseen target from a variety of angles, students can estimate the general size and shape of the target. Use this creative simulation to engage your students in one of the great discoveries of the atomic age. Includes eight wooden shapes, marbles, and all materials needed to construct eight “black boxes.” Reproducible student handouts, detailed background information, and Teacher Notes with sample data and answers to questions complete the kit.
Super Value Kit is complete for 8 student groups. All materials are reusable.
