The use of GFPs is simulated by adding fluorescent dye to water and allowing a flower or plant to transport the dye throughout its structure. Students apply their knowledge of GFPs to engineering applications in the medical, environmental and space exploration fields. Due to the fluorescing nature of the dye, plant life of any color, light or dark, can be used unlike dyes that can only be seen in visible light.

They use a fluorescent compound as the dye to track through a series of dilution steps. They observe how the changing color intensity, or saturation, of each subsequent solution. They also keep a running calculation of the concentration dye in each serial dilution. Finally, using a UV lamp, they investigate whether the fluorescent dye can be detected after it disappears from view under normal lighting conditions. Matthew D.

Students systematically dilute solutions of food coloring with pure water. They observe how the color intensity, or saturation, of each subsequent solution changes. They also keep a running calculation of the concentration of drops per ml water. They apply what they learn to discussions of biomedical engineers working with cells. Matthew D.
