CHEMISTRY

FIRST INTRODUCTION TO
MOLECULAR MODELS
Kit #129
Understanding molecular models is 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 .
The next activity deals with the three-dimensional structure of the
atom . Similarities in molecules are readily observed as students
connect atoms to similar atoms, such as by forming hydrocarbons .
Bonding is illustrated in constructing molecules with different atoms .
Accommodates unlimited classes, each with 12 groups of two students.

MOLECULAR MODELS AND
LEWIS DIAGRAMS
Kit #130

Colorful, easy-to-assemble models help students visualize
the construction of different molecules . Top quality reusable
components mean that comparison models can be made
simultaneously, then disassembled to make other models .
Introductory classroom kit includes twelve packets of color-
coded molecular model components .
Accommodates unlimited classes, each with 12 groups of two students.

ATOMIC STRUCTURE AND
CHEMICAL INTERACTIONS
Kit #141
Students are introduced to models of atomic structure and
use the planetary model to visualize the number of valence
electrons . They discover that the row of the Periodic Table
(chemical family) in which the element belongs is related
to the element’s number of outer shell electrons . They also
discover that the total number of electrons in the outer shell
of chemical compounds is a multiple of eight .
Accommodates unlimited classes, each with 12 groups of two students.
