Modern Physics

A collection of 40 simulated experiments and
interactive sequences that cover radioactivity and

atomic structure. The resource provides an
introduction to quantum mechanics, particle physics
and special relativity.

Topics covered:
• Rutherford’s alpha scattering experiment • Deflection of alpha
particles by a nucleus • Basic atomic model • Energy levels
• Deflection in a magnetic field • Penetrating properties
• Absorption of gamma rays • Geiger counters • Half-life
• Decay simulation • Radiometric dating • Nuclear fission
• Chain reactions • Nuclear reactor • Critical mass • Photoelectric
effect • Uncertainty Principle • Double slit experiment • Particles
• Fundamental forces • Feynman diagrams • Decay mechanisms
• Conservation laws • Neutrinos • Reference frames • Inertial
frames • Galilean relativity • Galilean transforms and Newton’s
laws • Maxwell’s equations • The Michelson - Morley experiment Penetrating properties of radiation simulation
• Postulates of special relativity • Lorentz transforms • Light clocks
• Time dilation • Simultaneity • Length contraction

Video Libraries

Never lose track of those useful YouTube
video clips ever again. Shipped with a default
starter library of Biology, Chemistry and
Physics links, when you come across a useful
video, simply copy and paste the URL into
your custom library editing tool, add it to a
topic category, and save. It’ll then be stored
for the next time you need it.

This tool is supplied with all three science libraries and is
part of our Science Resource Pack (p4-5).
NB: The video content is streamed from YouTube and not
produced by Focus Educational Software. View videos by category or search by key words
