Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"
In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Sulfur is the fourth in this series of elements to be discussed as part of the Element of the Month program. #IYPT
It is not known why people develop allergies to nickel and there is no cure. The best course of action to prevent an allergic reaction is to avoid contact with products containing nickel. This article will explain how to make an easy and cheap nickel detection device that will limit or eliminate the risks of exposure to sources of nickel using some interesting classic chemistry.
I will share how I use the Target Inquiry activity, Change You Can Believe In. I have realized that I need to include particulate models within the assessments after the lab to fully evaluate my student's conceptual understanding.
