This lesson introduces students to many of the basic properties of matter
including atoms, ions, elements, molecules, and density. The class explores an interactive flash-animated Web site to answer questions and clarify some misconceptions they might have had about matter. In groups, students concentrate on different aspects of the inquiry. Each group also participates in an online experiment in a section called "Do-It-Yourself."
