Florida State University provides a discussion of polarity of binary and polyatomic molecules, with tables and graphics.

In this StudyCard activity, students are asked to describe the geometry and polarity of several molecules and ions. Geometries covered include linear, bent, trigonal planar, trigonal pyramidal, and tetrahedral. Students will need to have...

When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works...

A series of pages that explain polarization, polarized light and its effects, polarized filters, and sunglasses. Interactive Java applets.

Young scholars develop their own water molecule model to help them understand the idea that water has a slight positive charge at one end of the molecule and a slight negative charge at the other.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will describe the structure and polarity of a water molecule. They will also describe the hydrogen bonding that occurs in...

Observe polarization of a molecule.

An interactive simulation that teaches about polarity, electronegativity, and bonds by changing the electronegativity of atoms and bond angles in a molecule to see how it affects polarity. This simulation can either be downloaded or...

Learners learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding...

An incredible series of illustrated pages that explain polarization, polarized light and its effects, and polarized filters and sunglasses. Features interactive Java applets.

Through this activity, students work with macromolecules, proteins and nucleic acids. The focus is on the atomic structure of proteins, how linear polymers are made, and the surface charges of the resulting polymers. . Multiple-choice...

This section in the online textbook describes how to tell if a molecule is polar or non polar. Detailed steps and examples are good references. Also find links to presentations and chapter maps for other chemistry topics.

This lesson will demonstrate how to use molecular shape to determine if a molecule is polar or nonpolar. It is 2 of 2 in the series titled "Polarity of Molecular Compounds."

[Free Registration/Login may be required to access all resource tools.] The following online tutorial describes how the electronegativity difference between two atoms in a covalent bond results in the formation of a nonpolar covalent,...

[Free Registration/Login may be required to access all resource tools.] Covers structure of water molecule, hydrogen bonding on water, polarity of water molecule, and bond angles of water molecule.

In this module students explore the properties of chemicals with covalent and ionic bonds. Students learn that there are different types of covalent bonds, polar and nonpolar, and that the type of covalent bond along with the shape of a...

Control the temperature and observe the impact on the motion and interactions between particles. Compare the interactions between nonpolar molecules and between polar molecules to see how polarity affects the boiling point of substances...

A module with animations, explanations, and questions about the importance of electrons in the structure of an atom. Understand the definition and locations of electrons in the atom. Explore the role of electrons in bonding, polarity,...

[Free Registration/Login may be required to access all resource tools.] Describes the three states of water.

[Free Registration/Login may be required to access all resource tools.] Describes the three states of matter of water.

This site from the University of Frostburg provides an explanation of the process by which nonpolar molecules dissolve in water.

Problem sets, tutorials, and activities related to biochemistry.

Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell...

This lesson will introduce polar and non-polar molecules, explaining their location, charge, and mass. It is 1 of 3 in the series titled "Polar and Non polar Molecules."
