Students explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

Students observe and manipulate the structure of a protein. They form an alpha helix, a beta sheet, and add disulfide bonds. They create a multimeric protein and compare their location with other students.

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Fourth graders, in groups, examine the effect of heat on bonding forces by doing laboratory work.
