- Students are placed into small groups and asked to find the probability that an unknown quantum wave state $\vert \psi \rangle$ will leave an x,y, or z-oriented Stern-Gerlach analyzer in either the spin-up or spin-down state.
- The probabilities can then be used to find the coefficients of the unknown wave state.
- This process is repeated for all four unknown wave states on the Spins program, with each unknown wave state more challenging to find than the last.
