Product Description
This 2-page isotope lab activity designed to be a short exercise that helps students gain experience with calculating percent abundance and average atomic mass using 3 different sizes of beans (lima, pinto or navy, and black eyed peas) to represent an element named "beanium" with 3 naturally-occurring isotopes.

To perform the activity, students examine a sample of beans (a sample ratio can be found in the answer key), count the number of different beans and perform 2 sequential calculations to discover the percent abundance of each "beanium" isotope and the average atomic mass. Once the calculations have been performed, students answer a short analysis questions that asks them to calculate how the average atomic mass changes when one isotope increases in quantity in the sample.

Introduction to the Activity (From the Lab Document)

In this activity, imagine that a new element has been discovered. The new element is called beanium, which has the chemical symbol Bn. The atomic number of beanium is 4 amu. There are 3 naturally-occurring isotopes of beanium. The lightest isotope is Bn-8, with a mass number of 8 amu. The intermediate isotope, Bn-9, has a mass number of 9 amu. Finally, Bn-10 is the heaviest isotope with a mass number of 10 amu. Your challenge is to calculate the average atomic mass of beanium based on a sample provided to you.


Contents:

Page 1 introduces the concept of isotopes, states the problem, materials, procedure, and provides a blank data table

Page 2 features 2 calculations in order to calculate the percent abundance of each isotope and the average atomic mass of beanium along with 1 short analysis question.

Pages 3-4 is a full color-coded answer key with sample student data.
