Radiometric dating practice problems with answers

This practice, called biomimicry, ranges from the simple—like football players’ under-eye anti-glare smudges, a tactic taken from raccoons and meerkats—to the complex, such as reflective-lens technology on satellite telescopes, borrowed from certain lobster eyes.Evolutionary philosophy holds that ingenious biological features were invented by the unknowing, uncaring, purposeless laws of nature, but it is clear that they were instead engineered by our wise, benevolent, and powerful Creator.Before then, the Bible had provided the only estimate for the age of the world: about 6,000 years, with Genesis as the history book.Hutton's theories were short on evidence at first, but by 1830 most scientists concurred that Noah's ark was more allegory than reality as they documented geological layering.The Genesis account of Creation provides mankind with just the bare facts we need to know about our origin.Further facts are revealed progressively throughout Scripture.Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4.6 billion years.

After all, the ever-changing Earth rarely left a complete geological record.This hands-on activity is a simulation of some of the radiometric dating techniques used by scientists to determine the age of a mineral or fossil.The activity uses the basic principle of radioactive half-life, and is a good follow-up lesson after the students have learned about half-life properties.Some natural systems, especially living systems, contain ingenious solutions for solving technical problems.Human inventors must solve the same physical problems in order to achieve similar results, and therefore many people are taking inspiration from pre-existing devices found in nature.
