Importance of PowerPoint Presentations in Chemistry

PowerPoint presentations are useful tools to illustrate abstract concepts in science. Students of chemistry may have difficulty visualizing, for example, atomic or molecular structure, electron orbital structure, or stoichiometry (the math behind chemistry). PowerPoint presentations can be used to consolidate and present information in a concise manner, and can also be made easily accessible to students on the web. Four general topics in chemistry can easily be illustrated using PowerPoint. Using the program has distinct advantages, primarily allowing students to visualize difficult concepts.
  1. Atomic Structure

    • The schematic of an atom in a PowerPoint presentation allows students to visualize atomic structure.

      The structure of an atom, characterized by a nucleus with protons and neutrons surrounded by electrons, can be illustrated in PowerPoint. A schematic of an atom can be drawn directly in PowerPoint, or a different file format can be imported directly into a presentation. Such illustrations help students visualize things that cannot be observed directly in the real world.

    Visualizing Atomic Orbitals

    • PowerPoint can demonstrate the motion of electrons in the orbitals.

      Atomic orbitals are mathematical functions representing the wave-like behavior of electrons around a nucleus in an atom. The four orbitals are named s, p, d and f, and are used to characterize orbital shape. The three-dimensional shapes of these orbitals can be illustrated using PowerPoint, and the animation capabilities can be used to convey the motion of electrons in the orbitals.

    Stoichiometry

    • PowerPoint is helpful when teaching groups of students chemical formulas.

      Stoichiometric equations represent the relationship between reactants and products in chemical equations. Balancing chemical equations is a skill taught in basic chemistry, and often requires considerable practice by students. PowerPoint can be used to present chemical equations to a large number of students, and animation can be used so an entire class can participate in the steps required to balance an equation.

    Organic Chemistry

    • Organic molecules are, by definition, composed of carbon. Beginning students of organic chemistry often have difficulty visualizing the complex three-dimensional structures of organic molecules. This is especially true when two molecules have the same chemical formula, but different bonding or branching patterns. PowerPoint is especially useful when illustrating such complex concepts as stereoisomerism.
