Interested in perhaps changing how you teach certain chemistry topics? Looking for relevancy to connect chemistry theory to applications? Take a look at the National Center for Case Study Teaching in Science collection (free downloads) housed at the State University of New York at Buffalo (SUNY-Buffalo).
The solution to Chemical Mystery #15: The Leaky Cup is shown here.
Determination of Lewis Dot structures and visualization of the shapes of molecules using VSEPR theory is an example of an abstract concept that students often find difficult to learn. I have found it useful to have a single worksheet/packet that my students can add to as we cover Lewis dot structures, resonance, VSEPR shapes, polarity, and intermolecular forces.
This lab is one of my favorite activities to do in my classes and I look forward to it every year. The lab is simple, requires limited supplies, students love it (i.e. high engagement level), and I have found it to really set students up for stoichiometry.
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
Time for a new chemical mystery! Watch the video below and see if you can use your chemical knowledge to figure out how this experiment is done.
This activity goes beyond having students calculate concentration and dilutions. Students prepare a solution and the instructor can use a simple test to evaluate the result.
Whiteboards are great learning tools in a science classroom. With these instructions, you can make eight 24-in x 24-in whiteboards for less than $2.00 each! Instructions for simple whiteboard stands are included.
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.
My name is Scott Donnelly, editor for the Two Year College (TYC) component of ChemEd Xchange. This is my first of what likely will be many contributions over the coming years. Since this is my inaugural post as the TYC editor perhaps I should let you all know a bit about myself and my educational philosophy.
