This paper presents computer-based laboratory activities which focuses student attention on the quantum mechanical models for translational motion, vibrational motion, and rotational motion. Using Mathematica, students investigated the two-dimensional particle in a box, the harmonic oscillator, and the particle on a sphere by graphing the wavefunction y and the probability density |y|2. Student understanding and achievement was measured using a post-lab survey, an examination question, and a question on the semester final. Students stated that they developed a better understanding of the concept of a wavefunction and a probability density. On the semester final, 88% of the students could correctly identify pairs of degenerate two-dimensional particle in a box wavefunctions.
