FAMILIES OF ELEMENTS EXPERIMENT

Kit #110R

Students learn how to classify elements by observing the behavior of compounds in the Halogen
Family (Group VIIA) . The chemical properties of this group are very similar despite the marked
differences in their physical properties .
As students perform a series of experiments, they discover that the elements form remarkably
similar compounds with silver . Also, that the formulas of the compounds are similar, and that the
elements are indeed in the same family .
Accommodates two classes, each with 15 groups of two students.

MODELING AND COMPARING FOSSIL
FUEL AND BIOFUEL COMBUSTION

Kit #38
®
In Part One of this activity, students use Lab-Aids Molecular Models
to build methane, ethanol, and octane molecules then “combust”
them with oxygen molecules . “Combusting” the model molecules
helps students determine the balanced chemical equations for the
combustion reactions and compare the amount of carbon dioxide
released when these three fuels are burned . In Part Two students
use standard bond energies to calculate and compare the amount of
energy released during the combustion reactions they modeled in Part
One . They are then asked to use their data about the energy released
and the CO produced to choose which fuel they think is better .

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