Biochemistry Experience on the Border

Hello, and welcome back to my second blog about chemistry education in the tri-border region of California, Arizona, and Mexico. In my last I described the area and students who attend the two institutions in Yuma, AZ- Arizona Western College (AWC) and Northern Arizona University-Yuma (NAU). In this second post I will talk briefly about my experiences teaching an upper-division biochemistry course. I presume that what I observe in my classes is not much different than what you observe in your classes. 

M&Ms as Isotopes

Use Mega M&Ms, M&Ms minis, and regular M&M’s in this activity to examine the concept of isotopes and average atomic mass. The color of the M&M’s represent that they are the same element and have the same number of protons. The size represents, in a relative sense, the different numbers of neutrons.
