INTRODUCTION TO OXIDATION
AND REDUCTION
Kit #88
Students place pieces of zinc, lead, and copper in solutions of
metallic ions to test their relative reducing ability . Then, they
compare and determine the relative oxidizing strength of
certain halogen elements: chlorine, bromine, and iodine .
This highly visible and safe activity is an excellent
introduction to a very important chemical concept .

Accommodates two classes, each with 12 groups of two students.

MODELING CHEMICAL EQUILIBRIUM

Kit #89
Students use an innovative Lab-Aids model to simulate the
®
simultaneous occurrence of forward and reverse reactions .
This mechanical system provides a simple look at dynamic
equilibrium and allows students to collect data that helps
develop the concept of chemical equilibrium and the
equilibrium constant (K eq) . They then use their understanding
to calculate the predicted results for other “reactions .”
of K eq
Accommodates dozens of classes, each with 6 groups of four students.

ELEMENTS AND THE PERIODIC TABLE
Kit #109S — Developed by SEPUP
This kit contains two activities . In Activity 1, students compare
pre-selected data on physical and chemical properties of 14
elements and sort the elements into groups based on common
properties. Then they compare their classifications with groups,
or families of elements, as defined by scientists. In Activity 2,
students are introduced to the Periodic Table of the Elements
and read about its history and organization. The reading
introduces the difference between elements and compounds as
well as atoms, molecules, and chemical formulas .
Accommodates unlimited classes, each with 12 groups of two students.
