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."

This general tutorial begins with an explanation of the polarity of the water molecule and the effects this polarity has on the properties of water. Goes on to introduce organic molecules and has a thourough tutorial on the third page.

Observe how molecules with hydrophilic and hydrophobic regions move in a mixture of oil and water, and pay attention to changes in potential energy over time. Move and rotate the molecules to see how they interact with their surrounding...

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

Frostburg State University provides a brief explanation to the question of why small hydrogen molecules, such as OH, NH, and FH, are very polar.

Adjust amounts of ionic charges in this simulation to see how water molecules react to polar substances in solution.

Media-rich lesson in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...

By working through this web-based activity, students differentiate between ionic, non-polar covalent, and polar covalent bonds. Specifically, distinctions are made between bonding types based on orbital shapes and electronegativity...

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

Students observe and investigate why water has a strong surface tension.

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...

This lesson will introduce polar and non-polar molecules, explaining their location, charge, and mass. It is 2 of 3 in the series titled "Polar and Non polar Molecules."

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

This lesson will provide an understanding of the chemical and physical nature of water. It is 3 of 4 in the series titled "The Properties of Water."

This lesson will provide an understanding of the chemical and physical nature of water. It is 1 of 4 in the series titled "The Properties of Water."

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

Page uses movies and 3D images to explain how properties of water relate to polarity and hydrogen bonding.
