VIDEO: Algebra Applications: Variables and Equations, 3 |
VIDEO: Algebra Applications: Variables and Equations, Segment 3: 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? |
|
VIDEO: Algebra Applications: Variables and Equations, 2 |
VIDEO: Algebra Applications: Variables and Equations, Segment 2: Honey Production.Honey bees not only produce a tasty treat, they also help pollinate flowering plants that provide much of the food throughout the world. So, when in 2006 bee colonies started dying out, scientists recognized a serious problem. |
|
VIDEO: Algebra Applications: Variables and Equations, 1 |
VIDEO: Algebra Applications: Variables and Equations, Segment 1: Introduction.An overview of the key topics to be covered in the video. This is part of a collection of videos from the Algebra Applications video series on the topic of Variables and Equations. |
|
VIDEO: Algebra Applications: Variables and Equations |
VIDEO: Algebra Applications: Variables and EquationsIn this episode of Algebra Applications, two real-world explorations are developed: Biology. Analyzing statistics from honey bee production allows for a mathematical analysis of the so-called Colony Collapse Disorder. Geology. Why do rivers meander instead of traveling in a straight line? |
