Additional Info

• ID Code: P4-41
• Purpose: Show difference in scattering from the Thompson and Rutherford models of the nucleus.
• Description: Small ball bearings representing alpha particles roll down an inclined groove to gain kinetic energy, then pass through representations of either Thompsons model (center) of the nucleus or Rutherford's model (right) of the nucleus. The angle of the track or the starting position for the balls can be adjusted to change the energy of the alpha particles.
