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.

Lesson Plan
  • Life of the Party # This activity teaches students how to determine the age of an atom using an onion, cabbage, and Brussels sprouts. Aliens from another planet left these items on our planet and need our assistance determining their age. Based on the number of layers or half lives of the "elements," the students will be able to determine their age. The students will also be able to differentiate between the three types of radioactive decay and understand why radioactive elements are harmful.
Text Resources
  • Where Do Chemical Elements Come From? # This informational text resource is intended to support reading in the content area. What is that extremely bright light in the sky? It's a supernova: the result of a massive star collapsing in on itself. This explosion is more than just a pretty sight; it is the main source of the elements that make up our planets and all the other objects in the night sky.
  • Are There Mysterious Forces Lurking in Our Atoms and Galaxies? # This informational text resource is intended to support reading in the content area. This article discusses a physicist's search for a new universal force, along with details regarding the four fundamental/universal forces (gravity, electromagnetism, strong nuclear force and weak nuclear force).
  • Magnetism # This site presents the basic ideas of magnetism and applies these ideas to the earth's magnetic field. There are several useful diagrams and pictures interspersed throughout this lesson, as well as links to more detailed subjects. This is an introduction to a larger collection on exploring the Earth's magnetosphere. A Spanish translation is available.
