Abstract
Physical oceanography and meteorology are often taught using complex mathematical
formulas and computer generated models, which may confuse and frustrate non-science
undergraduates. In contrast, in-class demonstrations that can duplicate global processes on a
small scale can be a great non-mathematical method to teach students physical processes. A
laboratory has been created for the OCN 201 Laboratory section that would adequately teach
concepts in physical oceanography through live demonstrations using a rotating tank, without
overwhelming students with mathematical formulae. The pre-laboratory handout, prelaboratory quiz, laboratory instructions, and laboratory assignment were designed after
performing a number of experiments using the tank. The Upwelling/Downwelling
demonstration was chosen due to its simplicity, relation to the lecture and previous laboratory
materials, as well as its ability to be repeated for multiple laboratories. It is expected that the
in-class demonstrations will not only excite and intrigue students, but also help them
understand how and why this process occurs. Results show students enjoyed watching the
demonstration as they could then visualize what happened in the ocean. With good feedback
from students, the rotating tank should be utilized more in additional laboratories.
