This demonstration lays the foundation for what science is all about: proper experiments, properly carried out, properly interpreted.
This engaging activity uses wrapped and unwrapped candy to simulate alpha and beta decay.
This flipbook activity helps students to identify and solve problems involving empirical formulas, molecular formulas and percent composition while also helping them see how they are related to each other.
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.
Organic nomenclature is usually taught as an introduction to organic chemistry. To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist, a paper tool for naming hydrocarbons was developed.
Infrared technology (FLIR Cameras) can be used to investigate intermolecular forces.
Observing the floating and sinking behavior of diet and sugared sodas is a classic chemistry demonstration. Learn how to perform this experiment as a quantitative lab that can be accomplished as an at-home activity!
Spectroscopy-based experiments are commonplace in college labs. This out-of-classroom activity post provides links to applications of spectroscopy in a diverse spectrum of disciplines and work fields.
Using the online simulation tool (Atomsmith Classroom Online) and the ADI framework students investigate the properties of gases, along with two gas laws. An ADI "whiteboard discussion" helps in getting students to really process what the results of experiments mean to us as chemists - and how this leads to expanding our understanding of matter. This activity lends itself to an online classroom.
