A serendipitous finding involving static magnetic fields can be used to design experiments suitable for both science and nonscience majors. It has been reported that organisms respond differently to high-gauss magnetic…
This column focuses on promoting learning through assessment. This month’s issue discusses the formative assessment probe “Can You Pick It up With a Magnet?” which is designed to find out what types of materials…
The valence-shell electron-pair repulsion model (VSEPR model) provides a simple way of predicting the molecular geometries. However, the particularly challenging part in demonstrating the VSEPR models is to show the “…
