Ward's® Core-Valence-Radius Periodic Table
Developed by Teacher James Ross, the Core-Valence-Radius Periodic Table is a new type of periodic table designed to make learning chemistry a more intuitive process. Each element is represented by a nucleus (core), a valence shell, and an electronegativity value.
Ward's® Laboratory Safety Poster Set
Ward's Laboratory safety poster set establishes rules in the lab.
Three Domains of Classification: A Phylogenetic Tree Study Kit
In 1977 Carl Woese of the University of Illinois shook the world of biology and its long established tree of life when he announced the discovery of an entirely new group of organisms – the Archaea. Dismissed by many, further proof was provided when a vent organism (Methanoccus jannaschii) was sequenced.
Today this new phylogeny is the basis for a range of new explorations in microbial biology from the origins of life to its diversity. Developed by Susan Offner and based on the pioneering work of Woese, this kit takes students to the cutting edge of evolution, classification, and beyond.
Includes: chart (61 cm x 91 cm), color transparency, student notebook (1 pad of 30 drilled worksheets), teacher’s guide.
Human Chromosome Genome Study Kit
Teaching tool for evolution and speciation, and DNA and protein synthesis.
