Activities

Small Group Activity

60 min.

Multivariable Pictionary

Students draw the 3D graphs of equations using three variables. They make choices for drawing a stack of curves in parallel planes and a curve in a perpendicular plane (e.g. substituting in values for \(x\), \(y\), or \(z\). )

Drawing 3-dimensional representations of functions of two variables

Time Evolution of a Quantum Particle on a Ring with Arms

Students use their arms to act out stationary and non-stationary states of a quantum particle on a ring.

Quantum Mechanics Time Evolution Arms Superposition Stationary States Non-Stationary States
