- The vision, mission and goals of the 1998 ARC/ORNL Teacher Leadership
Institute and the follow-up Dept. of Education/ORNL Internet Tutorial Project
are grounded in National Science Standards - specifically the Science Content
Standards for grades 5-8, Physical Science - Energy Transfer (http://www.nap.edu/readingroom/books/nses/).
-
- 1. Energy is a property of many substances and is associated with heat,
light, electricity, mechanical motion, sound, nuclei, and the nature of
a chemical. Energy is transferred in many ways.
-
- 2. Heat moves in predictable ways, flowing from warmer objects to cooler
ones, until both reach the same temperature.
-
- 3. Light interacts with matter by transmission (including refraction),
absorption, or scattering (including reflection). To see an object, light
from that object - emitted by or scattered from it - must enter the eye.
-
- 4. Electrical circuits provide a means of transferring electrical energy
when heat, light, sound, and chemical changes are produced.
-
- 5. In most chemical and nuclear reactions, energy is transferred into
or out of a system. Heat, light, mechanical motion, or electricity might
all be involved in such transfers.
-
- 6. The sun is a major source of energy for changes on the earth's surface.
The sun loses energy by emitting light. A tiny fraction of that light reaches
the earth, transferring energy from the sun to the earth. The sun's energy
arrives as light with a range of wavelengths, consisting of visible light,
infrared, and ultraviolet radiation.
