Description

Demonstrate the concept of a limiting reactant using
creative little gizmos. Using the average masses of the
gizmo components, students calculate the number of
gizmos that can be built from the materials provided.
They then determine the limiting reactant in their set
and the amount of each excess reactant left over. For
final conclusions and presentation, predicted results
are compared with the actual results. Developed
by Nancy Fischer, the kit includes instructions and
materials for 12 student groups. A balance that reads
to 0.01g is required, but not included. Grades 8–11.
