Noon Project Revisited
2200 years ago, Eratosthenes calculated the circumference of the Earth from the measurements of two shadows (in a well and from a pole). The Noon Project is an annual Internet event for schools to team up and make their own measurements. Using the reported 1995 shadow measurements, you can perform the calculations to determine the diameter of the Earth.

Pythagorean Theorem
The Really Rich Architecture Association is offering a million dollar reward for the first pair of engineers to determine the span between Monstrous Mesa and Cataclysmic Cliff over Ransacked River. This area is where they are planning to build an automobile bridge to reduce traffic fatalities and reduce commuter times for residents on both sides of the river. To these residents you will become a living legend. This lesson will provide you with the skills to solve the problem, win the reward and be the recipient of the undying adoration of thousands of people.
