Flag question: Question 6
The Half-life of Pennies Lab Can you use pennies to demonstrate "decay?
Imagine existing more than 5,000 years and still having more than 5,000 to go! That is exactly what the
unstable element carbon-14 does. Carbon-14 is a special unstable element used in the absolute dating
of material that was once alive, such as fossil bones. Every 5,730 years, half of the carbon-14 in a fossil
specimen decays or breaks down into a more stable element. In the following lab you will see how
pennies can show the same kind of "decay."
Materials • 100 pennies • large container with a cover
Procedure a. Place 100 pennies in a large, covered container. Shake the container several times and
remove the cover. Carefully empty the container on a flat surface, making sure the pennies don't roll
away. b. Remove all the coins that have the "head" side of the coin turned upward. Record the number
of pennies removed and the number of pennies remaining in the data table below.

John contrives an explanation: that the illness is waterborne and people are contracting the disease from water they retrieve from the town’s water pump. After petitioning the authorities, the handle at the pump is removed. John collects data about disease incidence and finds that occurrence of the disease is greatly reduced.

- Here is a simple example. The inhabitants of a small island begin exporting beautiful cloth made from a rare plant that grows only on their island. Seeing how popular the small quantity that they export has been, they steadily raise their prices. A clothing maker from New York, thinking that he can save money by "cutting out the middleman," decides to travel to the small island and buy the cloth himself. Ignorant of the local custom of offering strangers outrageous prices and then negotiating down, the clothing maker accepts (much to everyone's surpise) the initial price of 400 tepizes/m². The price of this cloth in New York is 120 dollars/yard². Part A If the clothing maker bought 500 m² of this fabric, how much money did he lose? Use 1 tepiz = 0.625 dollar and 0.9144 m = 1 yard.
