Promethean Flipchart: Algebra Applications: Biology 
All living things take up a certain amount of space, and therefore have volume. They also have a certain amount of surface area. The ratio of surface area to volume, which is a rational function, reveals important information about the organism. Students look at different graphs of these functions for different organisms.

Promethean Flipchart: Algebra Applications: River Ratios 
Why do rivers meander instead of traveling in a straight line? In going from point A to point B, why should a river take the circuitous route it does instead of a direct path? Furthermore, what information can the ratio of the river’s length to its straightline distance tell us? In this segment the geological forces that account for a river’s motion are explained. In the process, the socalled Meander Ratio is explored. Students construct a mathematical model of a meandering river using the TINspire. Having built the model, students then use it to generate data to find the average of many Meander Ratios. The results show that on average the Meander Ratio is equal to a factor of pi.
