Learn how basic elements form molecules to support life.

[Free Registration/Login may be required to access all resource tools.] Students investigate compounds, and learn the ways in which molecules are named.

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

In this activity, students construct models of molecules using marshmallows and gum drops.

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.

Explore and review the biological molecules necessary for life.

Students draw and interpret Lewis dot diagrams for individual atoms and both covalent and ionic compounds.
