OverviewMary and her classmates visit an exhibit at the Lawrence Hall of Science. The museum's visit will reinforce the concepts of atoms and how the atoms are joined together to form large molecules. An instructor introduces the rocks that are most commonly encountered in the Earth's crust. In rocks, in contrast to metals, the atoms tightly hold their valence electrons, and they do not flow through the material. This strong bonding means that stones do not conduct electricity and they are called Insulators. Rocks are made from atoms that do not belong to the group of Metals but from the group of Metalloids and Non-Metals.
