In this activity, students gain a better understanding of radioactive dating and half-lives. Parent isotopes are represented by the M side up radioactive. Daughter isotopes are represented by the M side down stable. They then set aside stable isotopes During each trial, students record the number of radioactive parent isotopes and record this in a data table.
Tamers was a director for university radiocarbon dating labs for twenty years before he commercialized radiocarbon dating analysis as Beta Analytic chairman and lab director. By innovating new techniques, keeping abreast of the latest technology, and training qualified scientists to stay ahead of demand, Beta Analytic has maintained its firm commitment to quality over the years.

Radiometric dating lab
Beta is able to offer rapid service because all analyses are done in-house. The lab has multiple accelerators with very high redundancy in spare parts ensuring that delivery times are met consistently.
The commitment to high-quality results and service has earned BETA the recognition of governmental, academic, and commercial organizations worldwide.
The lab has a dedicated full-time staff of technicians and scientists working overtime, if necessary, to meet its promised delivery times. Remove half the white beans and replace them with red beans.Using M & M's to Demonstrate Radiometric Dating
The red beans represent Nitrogen Red beans are the daughter isotope. This models the ratio of a fossil that is 5, years old.
Take Advantage of Beta Analyticís AMS Dating Expertise
Write the half-life age in the chart. Continue replacing half the white beans with red beans until only one white bean remains.
Each time, fill in the chart.
Answer the reflection questions after you have completed the chart. Would you be able to use this methodology to determine the age of a rock?
