Describe the quantization of energy at the atomic level.
Standard #: SC.912.P.10.9
Standard Information
General Information
Subject Area: Science
Grade: 912
Body of Knowledge: Physical Science
Idea: Level 2: Basic Application of Skills & Concepts
Standard: Energy -

A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc2.

B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion.

C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy.

D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields.

E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.

Virtual Manipulatives
  • Photoelectric Effect #
    This virtual manipulative will help the students to understand how the light shines on a metal surface. Students will recognize a process called as photoelectric effect wherein light can be used to push electrons from the surface of a solid.
    Some of the sample learning goals can be:
    • Visualize and describe the photoelectric effect experiment.
    • Predict the results of the experiment, when the intensity of light is changed and its effects on the current and energy of the electrons.
    • Predict the results of the experiment, when the wavelength of the light is changed and its effects on the current and the energy of the electrons.
    • Predict the results of the experiment, when the voltage of the light is changed and its effects on the current and energy of electrons.
  • Neon Lights and Other Discharge Lamps # This virtual manipulative will allow you to produce light by bombarding atoms with electrons. You can also visualize how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.

    Other areas to investigate:
    • Provide a basic design for a discharge lamp and explain the function of the different components.
    • Explain the basic structure of an atom and relate it to the color of light produced by discharge lamps.
    • Explain why discharge lamps emit only certain colors.
    • Design a discharge lamp to emit any desired spectrum of colors.
