Learning Goals Name the parts of a molecular structure, then build a hydrocarbon model and identify the atoms in it. If students have learned about atoms, review the following facts. If they haven't yet studied atoms, explain about matter and atoms. Matter, or anything that exists, is made up of particles called molecules. A molecule is made up of smaller particles called atoms.
Atoms are the smallest parts of things.
Discuss the information and clarify any misconceptions. Explain to students that they'll work in small groups to build models of simple molecules and name the atoms in each molecule. Web Work 1. Divide the class into groups of 4-5. 2. Explain that each group will be assigned a molecule to build from those shown on the Web site you are about to open.
