Take a “quantum leap” to see if you can determine the precise location of an electron around the nucleus of an atom! This engaging lab helps students visualize the shapes and relative positions of the 1s and 2s orbitals in a hydrogen atom. It also brings quantum mechanics to a more-understandable level-illustrating the concepts of probability, electron density, and Heisenberg's uncertainty principle. In this activity, students drop marbles onto specialized carbonless bull's-eye target sheets from various heights, examine the patterns formed, and relate the results to the maximum spot density of the s orbital.
Includes 30 printed carbonless target sheets, marbles, reproducible student instructions with data/graphing sheets, analysis questions, Teacher Notes, sample data and graphs. Also included is an optional performance assessment—for student evaluation and to help you meet the National Science Standards. Target Sheet Refill Pack includes 30 replacement printed carbonless target sheets—15 for waist-level and 15 for eye-level targeting.
Complete for 30 students working in pairs.
