About me:
Again, one of my favorite labs from one of my favorite topics! This lab is sort of a continuation of yesterday's lessonas it deals with a practical demonstration on half-life and radioactive decay. Students use pieces of candy to model the process of radioactive decay and chart their results in this hands-on assignment. Please note the materials section below. Also, it's important to note that students will be constructing graphs another of my favorites. While these aren't incredibly difficult, you may want to radioactive dating virtual lab more guided practice for them in building the graphs if you feel your students might need it. I use my document camera to go over the responses and model the correct answers usually with student participation.

Embed an image that will launch the simulation when clicked. Learn radioactive dating virtual lab different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Description: With the Half-Life Laboratory, students gain a better understanding of radioactive dating and half-lives. Students are able to visualize and model what is meant by the half-life of a reaction. By extension, this experiment is a useful analogy to radioactive decay and carbon dating. This experiment is best used by student working in pairs.
More about radioactive dating virtual lab:
At any given time t radioactive dating virtual lab, the number of remaining unstable isotopes as a function of time is:. Determine the age of a sample based on the following lab measurements:. You must select first an isotope 14 C, U, or Custom with selected half lifethen drag the probe to a sample and read the percent of the remaining radioactive atoms given in the upper left corner. Note 1. Note 2. You will have to use different isotopes for different samples. You will need more slowly decaying isotopes for the older samples. Purpose To determine the age of various samples by using different radioactive isotopes.
