6:
Interactions of Energy & Matter
Energy, such as potential, kinetic, and field, interacts with matter and is transferred during these interactions.

Objectives:

3. Electromagnetic waves result when a charged object is accelerated or decelerated. Sound waves and electromagnetic waves are fundamentally different.

Time Range:
3rd quarter; see previous objective

Suggested Teaching Strategies:
CPO Chapter 14 Section 1

• Students will define related vocabulary terms; use pre-reading guides to introduce them to the text; and fill in guided outline during class discussion.
• Have students draw and construct the electromagnetic spectrum and list applications of each type of electromagnetic wave.
• Demonstrate the relationship between wavelength, frequency, photon energy and wave velocity. Check student understanding through the use of worksheets.
• Have students identify individual unknown elements by comparison of emissions spectrum with emissions chart.

Aligned Resources:

• Supplemental materials: Prisms, light box, glow sticks, polarizing filters/tape, emission tubes, power source for emission tubes, diffraction grating glasses and lenses.
