Physical Science: Unit 3:
Waves
Time Frame:-3 weeks-January 7 – January 24, 2014
Unit Description and Student Understandings :
This unit thoroughly examines the properties of waves, including visible light and the electromagnetic spectrum and sound. Two activities in this unit provide earth science-based applications of physical science principles. These activities could also be completed along with activities of Unit 9, which is dedicated to earth science applications. Incorporating inquiry processes, students will examine and identify properties of waves as they relate to light and sound. The electromagnetic spectrum will be analyzed, and connections will be made among the phenomena of light, electricity, and magnetism. Students will be able to identify and explain the Doppler Effect .
Guiding Questions:
1.
Can student classify matter based on observable and measurable properties?
2.
Can student differentiate the types of mixtures?
3.
Can student describe how stated factors affect rate of dissolving?
4.
Can student utilize the kinetic molecular theory to describe the properties and structure of the different states of matter?
5.
Can students identify how thermal energy is transferred?
6.
Can student describe the behavior of matter during phase changes?
7.
Can student classify changes as chemical or physical?
8.
Key Concepts:

Waves travel through matters as energy is transferred from particle to particle.

Wave properties depend on the vibrations of the wave source and the material in which the wave travels

Waves interact with matter and with each other

Sounds waves are longitudinal waves that travel only through matter

The loudness of a sound depends on its intensity, and the pitch of a sound depends on its frequency

A musical instrument produces combinations of frequencies that determine how the instrument sounds

Sound waves are used to locate objects, to form images, and to treat medical problems

Vibrating electric charges produce electromagnetic waves

The electromagnetic spectrum is divided into several sections, each with certain range of frequencies and specific properties

Materials can absorb, transmit, or reflect light waves

Light waves of different wavelengths or combinations of wavelengths cause the human eye to detect different colors

Heating a filament and passing a current through a gas are common ways of producing light

Light can be used to form three-dimensional images and to transmit information in optical fibers

Mirrors from images by reflecting light rays
