An interactive simulation that teaches about molecules, photons, and absorption by exploring how light interacts with molecules in our atmosphere. Through this simulation students can get a better understanding of the importance of the...

When two or more atoms combine they give rise to a molecule. A molecule can be made up of many atoms of the same element. There are 112 elements known to man, so can you imagine the different permutations and combinations of molecules...

Understand the basic structure of atoms and molecules in the Earth's crust.

George Zaidan and Charles Morton shape our image of molecules. [3:47]

See how our DNA is tightly packed up so that six feet of this long molecule fits into the microscopic nucleus of every cell. [1:30]

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.

Online biology textbook discussing the chemical nature of water, and the importance of its molecular structure to life. Also discusses at length the organic molecules nucleic acids, proteins, lipids, and carbohydrates.

Explore the water molecule, and understand how it is a polar molecule.

In this online biology textbook, learn about atoms and molecules as they relate to life. Find out about topics such as electrons and energy, chemical bonding, and chemical reactions.

See how the discovery of DNA in 1953 sparked a new era of research into the code of life. [1:40]

In this hands-on lesson, students use candy to construct models of nutrients (carbohydrates, proteins, and fats). Create visualizations that will aid in learning about dehydration synthesis and bond saturation in fat molecules. Includes...

With this lesson, students create models of carbohydrates and proteins using pieces of candy in order "to visualize the atomic arrangements of nutrient molecules."

This page explains what electronegativity is, and how and why it varies around the Periodic Table. It looks at the way that electronegativity differences affect bond type and explains what is meant by polar bonds and polar molecules.

This chemistry class printout details the main points of molecular geometry and explains bond hybridization and bond angles.

A model that explores why electrons are so important in chemistry. Investigate electron clouds, what happens when two atoms come together, and chemical polarity.

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.

See how temperature changes affect dissolving and the molecular bonds in a water molecule.

This website offers a clear definition of the science of Genetics, highlighting DNA and genes. There is a neat, easy-to-understand animated tour of the basics and an opportunity to go inside an animated cell. Student can build a DNA...

These models show the structures of some basic molecules such as water and carbon dioxide, then move on to show more complex molecular strautures.

A collection of lesson plans for helping students understand atomic composition. Site uses work samples, phenomena, assessment templates, and videos to plan lessons to describe the atomic composition of simple molecules.

Find out about the process of transcription, where the DNA sequence of a gene is transcribed to make an RNA molecule.

This lesson plan explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. Young scholars think about how atoms and molecules can influence new...

Quiz yourself with questions related to the principles of bioenergetics and fuel molecule metabolism.

Learn how basic elements form molecules to support life.
