Product Description
Four page lab that using candy -MMs to teach the concept of isotopes and atomic mass. Could be modified for middle school level.

Procedure:
1. Obtain a sample of candium that contains three different brands of candy. Treat each brand of candy as an isotope of candium.
2. On a piece of paper towel, separate the three isotopes into groups labeled A, B and C, and measure the total mass of each isotope. Record the masses of each isotope in the Total Mass row of the data table.
3. Count the number of atoms in each sample. Record the number in the number row.
4. Follow the calculations described below to understand how to fill out the remainder of the data table.

Some Questions:
Questions
1. Explain the difference between relative abundance and percent abundance. What is the result when you total the individual relative abundances? The individual percent abundances?



2. Compare the total values for rows 3 and 6 in the table. Explain why the totals differ and why the value in row 6 best represents atomic mass.




3. Explain any differences between the atomic masses of your candium sample and that of your neighbor. Describe one change you could make to the procedure in order to make the difference smaller.
