Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...

Watch budding chemists interact with the resource on chemical interactions. In the unit, six lessons provide an overview of basic chemistry, from understanding the development of atomic theory to distinguishing between ionic and covalent...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Information on the biomedical use of nanotechnology, specifically in the detection and treatment of cancer, is the focus of a lesson that seems like it is out of a science fiction novel. Pupils learn about electrophoresis, which is used...
