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 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.
