Radiometric dating problems worksheet is dating your neighbor a bad idea

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 ().

However, to read any clock accurately we must know where the clock was set at the beginning.

Most people think that radioactive dating has proven the earth is billions of years old.

Each atom has a positively charged nucleus surrounded by negatively charged electrons.

The electric force between the nucleus and electrons holds the atom together.

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.

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.

In this way, they get practice reading graphs and using them to understand and interpret data.

Radioactive isotopes are unstable and undergo spontaneous nuclear reactions, emitting particles and/or wavelike radiation.
