Students examine the concept of frames of reference in physics: that two frames of reference, each moving with respect to the other with a constant velocity v, observe the same accelerations and therefore Newton's laws are the same in both. Full Review »

Students investigate the structure of atoms. Students read information about the Rutherford model, the Bohr model, and the Quantum Mechanical model examining each for its scientific validity. They watch a PowerPoint presentation of alpha particles interacting with a gold foil in a cloud chamber. Full Review »

Students use experiments such as electron diffraction that show that particle have a wavelike nature. When they are fired through a thin slit, rather than scattering like hard spheres they interfere lke waves. Students see that the result, Schrodinger developed a wave equaation for quantum particles.

Students trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them, and show, by the debate between particulate and continuous matter, the active process of scientific disagreement and the search for a better examineing of universal laws.
