1. Students calculate $\langle Sx\rangle$, $\langle Sy\rangle$, and $\langle Sz \rangle$ for a general time-dependent state
2. Each group does one calculation to make this time-efficient
3. The results are put together to form the general spin vector $\langle S(t)\rangle$
4. Students then consider what this looks like graphically
5. Students then consider what this looks like when starting in specific states (for example, an eigenstate of Sz)
