Why Do Elephants Have Wrinkled Skin? |
DescriptionHave you noticed how wrinkled an elephant's skin is? What purpose does it serve and what does math have to do with explaining this phenomenon? Well, the explanation for an elephant's wrinkled skin is almost entirely a math story. |

Slope and Grade |
DescriptionIn this lesson students learn how to use the slope formula to calculate steepness. In particular, students learn how to calculate steepness in the context of cycling. Cyclists use a measure called grade to calculate the steepness of a hill or mountain. Students apply their knowledge of slope to the concept of grade. |

Closed Captioned Video: Algebra Applications: Rational Functions, Segment 1: SubmarinesIn spite of their massive size, submarines are precision instruments. A submarine must withstand large amounts of water pressure; otherwise, a serious breach can occur. Rational functions are used to study the relationship between water pressure and volume. |

Closed Captioned Video: Algebra Applications: Rational Functions, Segment 2: BiologyAll 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. |
