Radiometric dating activity answer key

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.

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 ().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.Once you have a set of parent and daughter isotope beads in the bag, fill up the bag with a mixture of all the other colors.Next, label each bag with a number (1-5), put it at a separate station around the room, and make a sign that identifies the parent isotope type and color, daughter isotope type and color, and half-life.For instance, in fossil one, the students will take 15 divided by 60 and come up with the percentage .25.Next, they will look at the graph of decay and see that when 25% of the parent isotope atoms are left, the isotope has gone through two half-lives.Bár még javában zajlanak a nyári táborok, már lehet is jelentkezni az októberben megrendezésre kerülő Őszi Medve Matektáborba!Ha valaki a nyári tábor programjának 'Szomorkodás' pontját éli épp mert vége a tábornak, ne csüggedjen, 2018. között Püspökladányban újabb fantasztikus napot tölthettek velünk!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.
