Activities

Interactive
Demonstrations:
Use simple
molecular models
(physical or
digital) to
demonstrate how
differences in
electronegativity
and molecular
geometry lead to
polar or nonpolar
molecules.
Group Work:
Students work in
groups to model

Activity 1:
Molecular Model
Construction (2
hours) Students
will use ball-andstick kits or 3D
molecular
modeling software
to create various
molecules (e.g.,
H2O, CO2, NH3).
They will
determine whether
the molecules are
polar or nonpolar
by examining
electronegativity
differences and

Formative
Assessment:
Observation during

(molecular model
construction and
solubility lab).

Through interactive
modeling and realworld applications,
students gained a

Activity 2:
Solubility Lab (2
hours) Students
will conduct a
simple solubility
experiment to
observe the
relationship
between the
polarity of
substances and
their solubility in
polar and
nonpolar solvents
(e.g., salt in water,
oil in water). They
will predict and
explain the
outcomes based
on molecular
polarity.
