Students articulate an explanation of photosynthesis. They identify problems they have with comprehension of how a plant gains mass. Students describe a historical experiment.

Students observe the periodic table and draw the Lewis Dot Diagram.  In this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they...

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

In this chemistry of food worksheet, students complete 20 various types of questions related to food and nutrition. First, they complete a crossword puzzle with vocabulary terms. Then, students use the figure shown to write the...

In this acid-base worksheet, students solve multiple problems related to reactions of acids and bases. They determine pH of solutions, they find conjugate acids and bases, they calculate concentrations of acids and bases and they write...

High schoolers investigate the carbon dioxide content of different sodas. In this chemistry lesson, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Learners conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson plan, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

For this food additives worksheet, students will read information about the use of curing salt and ion nitrates to preserve food and the health problems that can occur from using these substances. Students will then answer 4 short answer...

Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...

This interactive activity developed for Teachers' Domain demonstrates how attractive forces between atoms create chemical bonds, resulting in the formation of molecules and compounds.

[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...

Review over covalent, hydrogen, and ionic bonding in this article. Learn how molecules are held together by chemical bonds.

Learn here about chemical bonds, a weak or strong electrical attraction that holds atoms in the same vicinity.

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

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...

Use this resource to understand polar covalence in ion-derived solids.

This is 21-question multiple choice quiz over chemical bonds was written for a 7th-grade science class.

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 bonds and seeks to answer the question, why do chemical bonds form?

[Free Registration/Login may be required to access all resource tools.] Definition of a chemical bond, why they form and the different types.

[Free Registration/Login may be required to access all resource tools.] Definition of a chemical bond, why they form and the different types.

[Free Registration/Login may be required to access all resource tools.] Examine the types of chemical bonding.

In this tutorial, students learn about ionic and covalent bonds and predict which elements will form which type of bond. Includes interactive exercises as well as videos.

Good introduction and graphics make this a solid page for understanding the orbital role in bonding and molecular geometry. The author is a professor at Florida State University.
