| Description | Students quantify the percent of light reflected from solutions containing varying concentrations of red dye using LEGO© MINDSTORMS© EV3 bricks and color sensors. They begin by analyzing a set of standard solutions with known concentrations of food coloring, and plot data to graphically determine the relationship between percent reflected light and dye concentration. Students quantify the percent of light reflected from solutions containing varying concentrations of red dye using LEGO© MINDSTORMS© EV3 bricks and color sensors. They begin by analyzing a set of standard solutions with known concentrations of food coloring, and plot data to graphically determine the relationship between percent reflected light and dye concentration. Then they identify dye concentrations for two unknown solution samples based on how much light they reflect. Students gain an understanding of light scattering applications and how to determine properties of unknown samples based on a set of standard samples. |
