High schoolers estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

Students participate in an angular solution of hydrogen activity. Using this activity, students also illustrate eigenvalue problems applied in mathematics. They explore Schrodinger's equation and particle wave duality.

Sixth graders explore how water behaves on a penny.  In this states of matter lesson, 6th graders observe water as they add drops to a penny. This lesson helps students apply the adhesive properties of water to the water cycle.

Pupils plot the locations of fallout from two disasters that polluted much of the world's air. They plot the ash fallout from the 1980 Mt. St. Helen's eruption to see what the wind patterns in the United States look like overall. Next...

[Free Registration/Login may be required to access all resource tools.] Covers polarity and covalent bonds.

Learn about London forces, which increase the attraction between polar molecules and the attraction between nonpolar molecules. Pictures and chemical structures allow for further understanding. Also find links for animations and...

[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,...

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...

[Free Registration/Login may be required to access all resource tools.] Polarity and covalent bonds.

[Free Registration/Login may be required to access all resource tools.] Covers solubility in water and polar molecules.

This site talks about ionic, polar covalent, and non-polar covalent bonding.

Simulations to show students the nature of chemical bonds. Simulations include an explanation of stereochemistry, atomic orbitals, chemical polarity, formation of an atom, and a summary quiz.

[Free Registration/Login may be required to access all resource tools.] Students will determine the polarity of a chemical bond using the electronegativity chart, and then distinguish between nonpolar covalent, polar covalent, and ionic...

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.

Excellent graphics help this page explain the relationship between electronegativity and bond polarity.

In this lesson, Mentos candy and different types of soda are used to show examples of nucleation, surface tension, surface area, polar attractions, and supersaturated materials. A video will be used to show the examples and the students...

[Free Registration/Login may be required to access all resource tools.] Students will be introduced to some of the basic concepts of chemistry.

The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section deals with chemical bonding and specifically the study of both polar and nonpolar...

Students 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.

Nine exemplary chemistry lessons about the water molecule and dissolving complete with handouts and animations.

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

Lesson plan with mulitmedia links in which students identify and control variables to help design a solubility test for different liquids in water.

Media-rich lesson in which learners 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...

Students use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.
