Explore the change in potential energy when molecules are separated from each other or broken apart.

The following module illustrates a method for determining if a molecule is polar or nonpolar.

Select an oil or water environment for molecules and observe how they are affected by interactions with their environment and each other.

Mix polar and nonpolar molecules together and observe changes in potential energy.

[Free Registration/Login Required] Learn the chemistry behind the ability of soap molecules to remove stains from clothing. The amphipathic nature of soap molecules is highlighted.

[Free Registration/Login may be required to access all resource tools.] Covers the structure and properties of water.

Activity 2 investigates How Hot Can Water Get? In Activity 2 students analyze the relationship between energy changes and phrase changes as they discuss what happens when water boils. Bonus reading includes Why is Temperature Constant...

Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many...

Lesson plan in which students design an experiment to determine if different types of liquids affect the amount of dissolution of an M&M candy shell.

A series of science simulations exploring how molecules assemble themselves and how scientists are learning to engineer their structure. Students will discover what patterns molecules form with interactive lessons. At the end there is a...

This simple interactive tool lets students explore the forces of attraction between polar and non-polar molecules.

Explains what intramolecular and intermolecular forces are and the different types for each. Includes lots of examples.

Problem sets, tutorials, and activities related to biochemistry.

Activity 4 investigates How does electron distribution impact our observations? Students have described how properties of molecules change depending on what atoms make up the molecule. In this activity students will use those ideas to...

Generate all polar, all nonpolar, or random proteins and observe how the protein folds in response to these molecular properties. Explore how the potential energy of the system changes over time to draw conclusions about how proteins...

An investigation of how polar and nonpolar interactions affect shapes of biological molecules and their function. Modules explore the following: 1. Why don't oil and water mix? 2. Can a substance dissolve in both a nonpolar and a polar...

A slideshow with several slides dedicated to electronegativity, the trend which is illustrated in the slide at this link. Others slides explain how the electronegativity can be used to determine bond character.

In this learning module from The Concord Consortium, students will investigate how polar and nonpolar regions in big molecules interact to result in certain shapes and properties for those molecules.
