2 Educational research has shown that “pounding” concepts into students’ heads through lecture only does not result in positive student learning and long- term retention of the concepts This Should Do It!

3 Variety of Methods Many concepts in science are not well-understood so a variety of teaching methods are encouraged by educational researchers.

4 Demonstrations It has been shown that using Demonstrations in the science classroom helps students retain concepts, energizes the science classroom and is more fun!

5 Key Terms: Wavelength Frequency Amplitude Speed Wave Characteristics

6 Types of Waves Transverse Longitudinal (compression) Torsional Surface Wave Types:

7 Reflection and Interference Reflection of Waves – “hard” boundary – “soft” boundary Wave Interference – Constructive – Destructive
