ChemEd X activities are student-centered resources intended to aid learning chemistry topics.

ChemEd X encourages engaging activities where students (with guidance from the teacher) pose questions, analyze data, and make observations to offer a plausible explanation supported by data and consistent with physical observations.

The lab activity shared here is a simple experiment where students use stoichiometric principles to experimentally determine the amount of sodium bicarbonate in an Alka-Seltzer tablet. Novice students tend to find stoichiometric calculations difficult, so practicing the calculations on a pre-lab assignment boosts their confidence and ultimately leads to more successful labs. The Asynchronous Video Pre-Lab Assignment shared here demonstrates the procedure and the calculations required in the experiment.

Atomic theory is a common topic throughout any introductory chemistry course. It is likely that Rutherford’s gold foil experiment gets at least some attention in your course. This simple activity gives students an opportunity to replicate Rutherford’s experiment through an analogy experiment that may allow for easier conceptualization of the experiment itself and provide additional support for model development.

Students use a micro-scale method to extract caffeine from tea using dichloromethane. At the end of the activity, the students' dochloromethane extractions are pooled; the solvent is distilled after class for re-use.

Many novice students struggle to see elements' valence electron configuration trends across the rows and columns on the periodic table. There are many diagrams and explanations available as resources for students however, a deeper understanding may be possible when students discover these trends independently through a game called Electron Configuration Battleship.

To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist in the IUPAC system, a series of paper tools were developed. The paper tool in this activity can be used to introduce the IUPAC naming of major classes of organic compounds. These paper tools are easy to print and distribute to every student each semester.
