Introduction to Molecular Modeling (507) In Stock Now

Comes as a class set of 6. Understanding molecular model made easy with this specially designed two-part kit. Students first study electron characteristics using the Bohr model for electron structure of the atom. They progress to a study of atoms gaining, losing, or sharing electrons in order to form molecules of a substance. Four-page student worksheets introduce students to molecular models by first using 2-dimensional color-coded atoms. Lewis diagramming can be taught with these models (directions included in instruction Manual). The next activity deals with the 3-dimensional structure of the atom. Similarities in molecules are readily observed as students connect atoms to similar atoms, such as forming hydrocarbons. Bonding is illustrated in constructing molecules with different atoms. Understanding the differences in empirical and structural formulas is emphasized. Students then progress to 3-dimensional, color-coded plastic atoms, building more realistic molecular models. The 2-dimensional and 3-dimensional atoms are colorful, easy-to-assemble and help students visualize the structure of the molecular formula that it represents. An excellent activity for all grade levels, it can be used for review as well as an introduction to atom-molecule concepts.
