Teacher Resources for Instructional Planning


HS, Physical Science Std 9: Compare methods of energy transfer by mechanical and electromagnetic waves. • Distinguishing between transverse and longitudinal mechanical waves • Relating physical properties of sound and light to wave characteristics Examples: loudness to amplitude, pitch to frequency, color to wavelength and frequency

Lesson Plans: Waves: Students will be able to state the properties that a medium must possess in order that waves may be transmitted through it. Students will be able to tell the essential difference between a longitudinal and a transverse wave. Wave Motion Identify and explain the difference between a transverse and longitudinal wave. Understanding Waves Students will gain an understanding of the properties that all waves have in common. The Phenomenon of Sound Students observe a variety of sound waves in lab stations and record their observations in a wave booklet. The Electromagnetic Spectrum Understand that the sun’s energy is transferred to Earth by electromagnetic waves. Earthquake Waves And Their Destructions Students will learn characteristics of primary waves and secondary waves. Transverse Wave Demonstrator Students construct an inexpensive device to demonstrate transverse waves. From Vibration To Sound To distinguish between a transverse wave and a compressional wave. Understanding Waves Students will gain an understanding of the properties that all waves have in common. Wave Properties In this lesson, students will learn the components of a wave, then discuss the effects of wave height, wavelength, and wave period in determining the overall size of a wave. Sound After this lesson, the student should be able to relate the pitch of sound to the length of a vibrating object. Ultrasound: How Does it Work? The second module shows how waves get reflected as they travel through objects. Nature of Light The main objectives of this mini-teach is for primary students to understand the Nature of Light. This will be accomplished by examples and demonstrations.
