Answer key available to classroom instructors with verifiable email addresses.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.Scientists from the Animal Cell Technology Unit published a paper in Scientific Reports journal that was now selected as one of the top 100 read papers in Cell Biology for Scientific Reports in 2017.i BET & Gen Ibet, through Pharma Portugal, were present for the first time at the CPh I North America 2018 - International Pharmaceutical Industry Convention, which ran from April 24 to 26 in Philadelphia, USA.The electric force between the nucleus and electrons holds the atom together.The atom's nucleus is composed of protons and neutrons, which are much more massive than electrons.In this way, they get practice reading graphs and using them to understand and interpret data.A good idea is to have the graph printed on the worksheet with the data table so that the students can have it right in front of them.

This ratio gives you the percentage of parent isotope atoms left after radioactive decay.
Instead of using exponents and natural logs, the students can just use a graph of predicted decay rates to determine the number of half-lives the isotope has gone through based on this percentage ().
As scientists, their job is to count the number of parent and daughter isotope atoms in each bag, and from this data to determine how many half-lives the isotope has gone through and therefore the age of the rock.
Have the students rotate in groups from station to station until they have figured out the age of all five fossils.
